ZHANG Kun-long, LI Wei-shuai, SUN Hong-zan, NAO Jian-fei, ZHENG Dong-ming
DOI: DOI:10.12117/jccmi.2020.04.001
Objective: To investigate the changes of cerebral blood perfusion and gray matter volume in patients with mild Alzheimer’s disease(AD). Methods: Magnetic resonance imaging(MRI) scanning including 3D-T1WI and 3D pseudo-continuous arterial spin labeling(3D-pcASL) sequences was performed in patients with mild Alzheimer’s disease and cognitively normal elderly. Statistical analysis of the differences of whole brain perfusion based on voxel in cerebral blood flow(CBF) map of the whole brain of the two groups of subjects was performed using Statistical Parametric Mapping(SPM) 8 software. Voxel-based morphometry(VBM) was used to compare the difference of whole brain gray matter volume between the two groups. Correlation analysis was performed between the CBF of the brain region with different perfusion and the Mini-mental State Examination(MMSE) score. Results: A total of 26 patients with mild AD(age (73.0±6.8) years, 16 males) and 53 age-sex matched healthy controls(age (73.7±8.2) years, 23 males) were included. Compared with the normal control group, the decreased CBF perfusion areas in the mild AD group were mainly located in the bilateral parietal lobe(precuneus, angular gyrus), occipital lobe and left temporal lobe and frontal lobe, the increased CBF perfusion areas were mainly located in the right hippocampus and parahippocampal gyrus, right cingulate gyrus and basal ganglia and bilateral frontal lobes(orbitalis and medial side)(P<0.01, FDR correction, Bulk threshold>100 pixels). The gray matter atrophy in patients with mild AD was mainly located in the bilateral medial temporal lobe structure(hippocampus, parahippocampal gyrus, amygdala), and also involved the bilateral insular lobes and basal ganglia nuclei(P<0.01, FDR correction, Bulk threshold>100 pixels). The CBF values of the left temporal parietal gyrus and bilateral superior frontal gyrus were positively correlated with the MMSE scores in the mild AD group. The CBF values of the bilateral medial and lateral cingulate gyrus and the right anterior cingulate gyrus were negatively correlated with the MMSE scores(P<0.05). Conclusion: In mild AD patients, there are mainly low perfusion in the parietal lobe and high perfusion in the hippocampus, basal ganglia and frontal lobe, while gray matter atrophy is mainly concentrated in the medial structures of bilateral temporal lobes.

DOI: DOI:10.12117/jccmi.2020.04.002
Objective: To evaluate MRI findings of enlarged perivascular space(EPVS), white matter hyperintense (WMH) and lacunes of cerebral small vessel disease(CSVD) in patients with systemic lupus erythematosus(SLE). Materials and Methods: Twenty-nine SLE patients and twenty-nine age- and sex-matched healthy subjects participated in this retrospective study. EPVS, WMH, and lacunes were rated by two radiologists. SPSS 24.0 was used for data statistical analysis, Kolmogorov-Smirnov Z test was used to analyze group difference, and Spearman correlation analysis was used to analyze the correlation between CSVD and clinical and laboratory examination. Results: In the centrum semiovale(CS), the EPVS score in the SLE group was higher than that in the control group(2.52±0.91, 1.34±0.55, P<0.01). The periventricular hyperintense(PVH) and deep white matter hyperintense(DWMH) in the SLE group were more significant than those in the control group(P<0.01), and the incidence of lacunes in SLE group was higher than that in the control group(P<0.05). In SLE group, EPVS in the CS and PVH were correlated with complement C3(r=0.505, 0.400, P<0.05), EPVS score and WMH were positively correlated with disease duration(r=0.460, 0.428, 0.416, 0.404, P<0.05). Conclusion: Cerebral small vessel disease is a common manifestation of central nervous system lesions in SLE patients and is associated with complement C3 and disease duration.

ZHAN Ya-ru, HE Lai-chang, TAN Yong-ming, GUO Jian-qiang
DOI: DOI:10.12117/jccmi.2020.04.003
Objective: To observe the characteristics of retrograde Wallerian degeneration of corticospinal tract(CST) in patients with cervical spondylotic myelopathy by diffusion tensor imaging(DTI), and to analyze the relationship between the degree of damage of corticospinal tract and limb motor dysfunction. Materials and Methods: A total of 28 CSM patients and 28 sex-, age- and education-matched healthy controls underwent conventional MRI and DTI examinations. The fractional anisotropy(FA) values and apparent diffusion coefficient(ADC) values of ROI in the bilateral pons, cerebral peduncle, posterior limb of internal capsule, periventricular, centrum semiovale, and subcortical white matter were measured. All subjects were scored for clinical motor function. To analyze the changes of FA and ADC values in each ROI area, and to explore the correlation between these changes and clinical scores. Results: There was no significant difference in FA values and ADC values between the left and right ROI of the CSM group(P>0.05). Compared with the healthy control group, the FA values of the various levels of CSM were reduced(P<0.05), and the ADC values of the centrum semioval, the posterior limb of the internal capsule and the pons were increased(P<0.05). The JOA score of the CSM group was lower than that of the control group(P<0.05), and correlated with the FA values of the pons, cerebral peduncle, posterior limb of internal capsule, and the ADC value of the posterior limb of internal capsule. Conclusion: DTI can detect secondary retrograde Wallerian degeneration of CST in patients with CSM, and this retrograde secondary degeneration of CST is associated with the impairment of motor function.

Objective: To evaluate the value and correlation of the ratio of apparent diffusion coefficient(ADC) of tongue lesions and surrounding normal glands in the diagnosis, pathological grading and staging of tongue cancer. Methods: Sixty patients with tongue lesions confirmed by surgical pathology in China-Japan Union Hospital of Jilin University from March 2017 to March 2019 were collected. Routine MRI and DWI scanning were performed before operation, and the ADC values of lesions and surrounding glands were measured and the ADC ratio was calculated. Results: ①There were 40 cases of tongue cancer and 20 cases of tongue benign lesions. The ADC ratio of tongue cancer was -0.13±0.17 and that of tongue benign lesions was 0.09±0.10, and the difference between the two ratios was statistically significant(t=5.129, P<0.05). ②The ADC ratio of the highly differentiated group was 0.02±0.07, the ADC ratio of the moderately differentiated group was -0.14±0.17, and the ADC ratio of the low-differentiated group was -0.26±0.09. There were statistically significant differences among the three groups(F=3.593, P=0.047). ③The ADC ratio of the advanced tongue cancer group(T3+T4) was -0.20±0.13, which was lower than that of the early tongue cancer group(Tis+T1+T2), the ADC ratio of the early tongue cancer group was 0.00±0.17(t=3.314, P=0.03<0.05). The difference between T4 and T1 and T2 was statistically significant(P<0.05), while no significant difference was found in other pairwise comparisons(P>0.05). Conclusion: The apparent diffusion coefficient ratio can provide reference for the differential diagnosis of benign and malignant tongue lesions and the pathological classification and staging of tongue cancer, and has important clinical significance.

DOI: DOI:10.12117/jccmi.2020.04.006
Objective: To evaluate the image quality of low-dose coronary CTA combined with iterative model reconstruction(IMR) in coronary arteries and its diagnostic value for coronary stenosis in patients with suspected coronary heart disease. Methods: Eighty patients with suspected coronary heart disease who underwent coronary CTA and the catheter coronary angiography(CAG) in our hospital were analyzed retrospectively. The image quality of each coronary artery was divided into 4 grades. Coronary angiography showing coronary artery luminal diameter reduction>50% as positive standard, the sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV) and accuracy of coronary CTA in the diagnosis of coronary artery stenosis were analyzed at the level of coronary artery segment and main artery. Patients were divided into two groups according to the Agaston score(group A <400, group B≥400). The difference in diagnostic efficacy between the two groups was compared. Results: At the segment level, 98.1% of the coronary images were qualified, and the sensitivity, specificity, PPV, NPV and accuracy of CTA were 93.2%, 98.0%, 91.3%, 98.4% and 97.1% respectively. At the level of main artery, 96.6% of coronary images were qualified, and the sensitivity, specificity, PPV, NPV and accuracy of CTA were 84.6%, 93.0%, 88.9%, 90.1% and 89.6%, respectively. There were significant differences in specificity, PPV and accuracy between groups A and B(99.2% & 91.8%, 95.7% & 84.2%, 97.9% & 93.7%, P<0.05). Conclusions: Low-dose coronary CTA combined with IMR can obtain satisfactory image quality and has high diagnostic accuracy for coronary artery stenosis. However, the diagnosis of severely calcified segments is still limited.

DOI: DOI:10.12117/jccmi.2020.04.007
Objective: To explore the left ventricular systolic function in patients with atrial fibrillation(AF) and normal left ventricular ejection fraction(LVEF) using automated function imaging(AFI). Methods: Thirty patients with AF and normal LVEF were enrolled as AF group and thirty matched subjects as control group, left atrial diameter(LAd), left ventricular end-diastolic diameter(LVEDd), left ventricular end-systolic diameter(LVESd), LVEF were measured. The left ventricular strain of(GLPS-LAX, GLPS-A4C, GLPS-A2C) and average strain(GLPS-AVG) were acquired by AFI function. Results: General ultrasound: age, heart rate, LAD, LVEDd, LVESd were higher in the AF group than those in the control group(P<0.05), while there was no significant difference of LVEF between the two groups. GLEF-LAX, GLPS-A4C, GLPS-A2C and GLPS-AVG in the AF group were significantly lower than those in the control group(P<0.05). Conclusion: Although the LVEF is normal in patients with AF, the left ventricular myocardial segment systolic function and overall systolic function have been reduced. AFI function can evaluate left ventricular systolic function in patients with AF quickly and quantitatively and provide valuable clinical information.

ZHAO Ying1, LIU Ai-lian1, CHEN Li-hua1, GUO Yan2, LI Ye1, SONG Qing-wei1, NIU Miao1, YANG Wei-ping1
DOI: DOI:10.12117/jccmi.2020.04.008
Objective: To investigate the value of whole-tumor histogram analysis of apparent diffusion coefficient(ADC) and fractional anisotropy(FA) signal intensity derived from diffusion tensor imaging(DTI) in differentiating intrahepatic mass-forming cholangiocarcinoma(IMCC) and solitary hypovascular hepatic metastases(SHHM). Methods: The data of liver MR scanning in our hospital were retrospectively collected, 24 cases of IMCC were pathologically confirmed, and 29 cases of SHHM were confirmed by pathology or follow-up imaging. ADC and FA maps were derived using Functool software on GE AW4.6 workstation, where ADC and FA values were measured. ADC and FA maps were transferred to Omni-Kinetics software(GE Healthcare), and ROIs covering the entire tumor were drawn on each slice of ADC and FA signal intensity maps. Histogram related parameters based on ADC and FA signal intensity, including min intensity, max intensity, mean value, the 10th, 25th, 50th, 75th and 90th percentiles, standard deviation, mean deviation, relative deviation, skewness, and kurtosis, were generated automatically after 3D ROIs covering the whole tumor were delineated by the readers. Comparison of the above parameters between the two groups was tested. Receiver operating characteristic(ROC) curves were plotted to analyze diagnostic efficiency. Results: The ADC and FA values between IMCC and SHHM groups were not statistically different(P>0.05). There was a significant difference in relative deviation of ADC signal intensity between the IMCC(13.76(5.44, 26.87)×102 and SHHM (2.41(1.12, 5.10)×102 groups(P<0.05). Moreover, a significant difference was observed in mean deviation and relative deviation of FA signal intensity between the IMCC(78.84(70.22, 115.37) and 22.09(9.29, 59.62)×102) group and SHHM (67.99(60.92, 89.39) and 3.16(1.19, 11.32)×102) group(P<0.05). The mean value and 10th percentile of FA signal intensity of IMCC group were statistically lower than those of SHHM group(P<0.05). The remaining parameters were not statistically different between two groups. The area under ROC curve of relative deviation of ADC and FA signal intensity were 0.828 and 0.848, respectively. The sensitivity/specifcity of ADC and FA were 79.2%(82.8%) and 87.5%(69.0%), respectively. Conclusion: Routine ADC and FA values of DTI are not efficient for identifying IMCC and SHHM. However, whole-tumor histogram analysis method based on ADC and FA signal intensity can provide multiple quantitative parameters for differentiating IMCC and SHHM.

DOI: DOI:10.12117/jccmi.2020.04.009
Objective: To investigate the imaging findings and pathological features of hepatic and splenic angiosarcoma and to improve the diagnostic level of imaging. Methods: The clinical and imaging findings of 6 hepatic and splenic angiosarcomas confirmed by operation and pathology were retrospectively analyzed and compared with pathological results. Results: Six cases of hepatic and splenic angiosarcoma occurred in liver(3 cases), spleen(2 cases), both liver and spleen(1 case). One case was single mass type, 1 case was multiple nodular type, 1 case was massive type, 1 case was mixed type, 1 case was diffuse nodular type, and 1 case had no obvious nodule and lump. Among them, T1WI high-signal hemorrhage was found in 2 cases, and 1 case had multiple lesions around the main lesion. In 5 cases of CT/MRI enhanced scan, all of them showed uneven centripetal and delayed enhancement. One case of diffuse nodular type showed nodular and reticular continuous enhancement and filling to the interior, and one case of multiple nodular type showed different nodular signals, the strengthening methods were also different, some of them showed the characteristics of progressive centripetal enhancement, some were ring-shaped enhancement, and the other 3 cases showed uneven centripetal and delayed enhancement of the lesion edge. Pathological findings showed that the tumor cells were mostly strips, epithelioid and nest like, and the vascular lumens of different sizes were anastomosed with each other, and tumor cells grew along the vascular lumen, and some of them showed papillary structures, some of tumors had hemorrhage and necrosis. Conclusion: The hepatic and splenic angiosarcoma usually presents as mixed density/signal mass on plain scan, and cystic change and hemorrhage are common in the lesion. CT/MRI enhanced scanning is of great significance for the diagnosis of angiosarcoma, most of which are annular or irregular enhancement at the edge of the lesion or in the central arterial phase, and centripetal or centrifugal progressive enhancement in the venous and delayed phases.

Objective: To explore the MSCT findings and pathological features of serous cystadenoma of the pancreas(SCP). Methods: The MSCT findings of 43 patients with serous cystadenoma of pancreas confirmed by operation and pathology were analyzed retrospectively. The location, size, cyst type, central scar, calcification and enhancement characteristics of the lesions were observed. Results: In 43 cases of SCP, 34 cases were serous microcystic adenomas(SMA), the average diameter of cysts was (4.2±0.5) cm. Among 34 cases of SMA, 29 cases of polycystic honeycomb type had multiple thick and thin uneven honeycomb septum with thickness of 0.03～0.2 cm, 5 cases of polycystic sponge type had mixed density of cysts and solid, and the cystic septa was unclear. Among 34 cases of SMA, there were 14 cases of central starlike fibrous scars, 14 cases of radial or gritty calcification in mass and spotted calcification in cyst wall, and 4 cases of upstream pancreatic duct dilatation. There were 9 cases of serous oligocystic adenoma(SOA), including 4 cases of single cyst type, which were round or oval, with an average diameter of (3.1±3) cm, 5 cases of polycystic type, which were lobulated and consisted of several small cysts with thin and smooth cyst wall, with a cyst wall thickness of <0.1 cm. The enhancement showed that the cystic septum, central star-shaped scars and solid components of SMA were mostly mild to moderate enhancement, the more cystic septum and solid components, the more obvious the strengthening, the central fibrous scar was delayed enhancement, no enhancement in the cyst of the SOA, only mild enhancement of the cystic wall and cystic septum. Conclusions: CT findings of SCP have certain characteristics. On plain CT scan, SMA is honeycomb or sponge-like, starlike fibrous scar and radiate calcification are seen in the center of the tumor, and the wall of the cyst, the septum and the solid part are lightly or moderately or significantly enhanced, which is characterized by delayed enhancement of central fibrous scar, SOA consists of single or several large cysts without central fibrous scar and calcification, slight enhancement of cystic wall and cystic septum is characteristic.

DOI: DOI:10.12117/jccmi.2020.04.011
Objective: To explore the value of T1 mapping in assessing grades of uterine cervical cancer. Methods: Seventy patients with pathologically proven cervical cancer and 30 patients with normal cervix underwent conventional MRI and DWI before therapy. Seventy cases of cervical cancer, including 56 cases of squamous cell carcinoma and 14 cases of adenocarcinoma, were divided into well/moderately differentiated tumor group(n=49) and poorly differentiated tumor group(n=21) according to the degree of pathological differentiation. Look-Locker sequences were performed pre and post contrast separately at 5 min after Gd-DTPA administration. T1 relaxation times(T1pre and T1post) and ADC of tumor and normal cervix were measured. The differences in the parameters between cervical cancer and normal cervix, tumor types/grades were compared, and ROC curve was drawn with statistically significant parameters. Results: The difference of T1pre, T1post and ADC was statistically significant between cervical cancer and normal cervix(P＜0.001). There was no significant difference in T1pre, T1post and ADC between squamous cell carcinomas and adenocarcinomas. Compared to the well/moderately differentiated tumor group, poorly differentiated tumor group showed increased T1post and decreased ADC(P=0.000 and P=0.002, respectively). No significant difference was observed for T1pre in differentiated grades of tumor. The areas under ROC curve of T1post and ADC for diagnosis of well/moderately and poorly differentiated tumor were 0.766 and 0.736. Conclusion: Enhanced T1 mapping can reflect the degree of tissue differentiation of cervical cancer to a certain extent.

Objective: To evaluate the value of diffusion kurtosis imaging(DKI) quantitative parameter histogram analysis in differentiating uterine carcinosarcoma(UCS) from degenerative hysteromyoma(DH). Methods: The data of 11 patients with UCS and 22 patients with DH confirmed by operation and pathology were retrospectively analyzed. All patients underwent pelvic DKI scanning, quantitative parameters of DKI, including mean kurtosis(MK), mean diffusivity(MD), fractional anisotropy(FA), were obtained after post-processing. Histogram analysis was performed using Omni-Kinetics software, histogram parameters, such as median, average, standard deviation, skewness, kurtosis, 25th percentile, 75th percentile, energy, and entropy were obtained. The independent samples t test(normal distribution) or Mann-Whitney rank sum test(skewed distribution) were used to compare the differences of histogram parameters between UCS and DH. Receiver operator characteristic(ROC) curve was used to evaluate the effectiveness of histogram parameters with statistical differences in differential diagnosis of UCS and DH. Results: There were significant differences in MK(standard deviation, 75th percentile, entropy), MD(median, average, 25th percentile, 75th percentile), FA(median, average, standard deviation, 25th percentile, 75th percentile, energy, entropy) between the two groups(P<0.05). There were no significant differences in MK(median, average, skewness, kurtosis, 25th percentile, energy), MD(standard deviation, skewness, kurtosis, energy, entropy), FA(skewness, kurtosis) between the two groups(P>0.05). The area under ROC of FA(median, 75th percentile) was the largest(0.921). The sensitivity of FA(75th percentile) was the highest(100.0%) and the specificity of MK(standard deviation) was the highest(100.0%). Conclusion: Histogram analysis of DKI quantitative parameters is helpful to distinguish UCS from DH.

DOI: DOI:10.12117/jccmi.2020.04.013
Objective: To analyze the results of 533 cases of infant developmental dysplasia of hip(DDH) screened by ultrasound, and to follow up the therapeutic effect, so as to provide the basis for clinical treatment. Methods: From May 2012 to June 2017, a total of 21 281 cases of suspected DDH in our hospital were analyzed retrospectively. The acetabulum shape and measurement values of α, β angle in the ultrasonic examination results of the above cases were observed. Graf method was used to classify the development of the hip joint, and the distribution of DDH was analyzed, and the treatment effect was followed up. Results: Among 21 281(42 562 hips) cases of suspected DDH, the positive rate of DDH examination was 2.50%(533/21 281). Among the DDH children, there were 413 female infants and 120 male infants. There were 95 cases of bilateral DDH(190 hips). Four hundreds and fifty-seven cases of DDH on the left and 171 cases of DDH on the right. One hundred and seventy-six DDH children received hip abduction exercise, and 164 returned to normal. One hundred and fifteen DDH children received Pavlik sling treatment, 104 returned to normal. Five patients received gypsum fixation after closed reduction, and all returned to normal. Conclusion: There are more female infants than male infants in DDH, more on one side and more on the left side than on the right side. The positive rate of clinically suspected DDH is about 2.5%. Hip abduction exercise is the preferred conservative treatment for type Ⅱ hip joint, especially for type Ⅱa hip joint. Pavlik sling is the first choice of conservative treatment for DDH children. Gypsum fixation after closed reduction is especially suitable for children who are older than one month old, who have failed in the treatment of hip extension exercise and Pavlik sling.

DOI: DOI:10.12117/jccmi.2020.04.014
Objective: To explore CT and MRI findings of spinal chondrosarcoma and to improve the understanding of this tumor. Methods: The imaging findings of 33 cases of chondrosarcoma of spine confirmed by clinical and pathological examination were analyzed and compared with the pathological results. Results: There were 33 cases of chondrosarcoma of the spine including 17 males and 16 females, with an average age of 41.4±11.6 years. Twenty-five cases, 5 cases and 3 cases were located in cervicothoracic spine, lumbar spine and sacrum spine, accounting for 75.8%, 15.2% and 3% respectively. Twenty-two cases, 9 cases and 2 cases were located in spine, paraspinal and intraspinal region, accounting for 66.7%, 27.3% and 6% respectively. Bone destruction was seen in 19 cases, but not in 14 cases, accounting for 57.6% and 42.4% respectively. The bone destruction was located in vertebral body, attachment and both of them, accounting for 15.1%, 27.3%, 42.4% respectively. Fifteen cases of tumor showed exogenous growth, accounting for 45.5%, 29 cases with paravertebral soft tissue mass. Fifteen cases of bone destruction were not in proportion to the soft tissue mass. Calcification was seen in 24 tumors, with various calcifications including punctate(9 cases, 37.5%), annular(2 cases, 8%) and irrgular(13 cases, 54.1%). Pathological resuts showed that 26 cases were common type, 5 cases were mesenchymal type, 1 case was transparent type and 1 case was dedifferentiated type.
