GAO Li-zhen1, QIAN Yu-quan1, ZHANG Bing2, LIU Jun3
DOI: 10.12117/jccmi.2020.05.001
Objective: To investigate the cerebral parenchymal blood perfusion status in hyperintense vessel sign(HVS) area on fluid attenuated inversion recovery(FLAIR) sequence during acute cerebral infarction and to evaluate the relationship between HVS change and short-term prognosis. Methods: Sixty-seven patients with acute cerebral infarction in middle cerebral artery(MCA) blood supply area without thrombolysis treatment were divided into HVS negative group and HVS positive group according to the presence of HVS. Cerebral blood volume(CBF) value of “HVS-DWI” mismatch area or around the infarct was obtained by 3D-pulsed arterial spin labeling scan. The relationship between HVS and NIHSS score, infarction area, rCBF was analyzed. The relationship between HVS and the change of the disease was observed in 13 HVS positive patients. Results: HVS sign was observed 38(56.7%) of 67 enrolled cases. NIHSS score and the infarction area of HVS positive group were higher than those of HVS negative group(P<0.05). The rCBF value of mismatched areas of “HVS-DWI” was decreased(P=0.012<0.05). Among the re-examination patients, there was no significant change in the range of HVS in 5 patients, with new infarction and progressive disease. Conclusion: In acute cerebral infarction, the appearance of HVS suggests severe neurological dysfunction and large infarction area, and the cerebral parenchymal blood flow in the“HVS-DWI” mismatched areas is hypoperfusion, and the persistence of HVS needs to be vigilant for new infarction.

DOI: 10.12117/jccmi.2020.05.002
Objective: Using HR-MRI to explore the characteristics of arterial remodeling(including topical and general) in patients with symptomatic basilar atherosclerosis. Methods: Patients with symptomatic basilar atherosclerosis who were included in HR-MRI were divided into two groups according to whether there was infarction in the blood supply area of basilar artery (BA). 3D-VIAST T1WI imaging was used to measure and compare the plaque and wall characteristics of the patients, including plaque burden, plaque area, perivascular area, topical remodeling type and plaque enhancement degree, etc. Patients with plaque but without infarction were normal controls. The BA area and BA diameter were compared among the three groups to observe the difference of BA general remodeling. Results: There were 12 patients in the BA infarction group(plaque number: 19), 15 patients without BA infarction(plaque number: 18) and 17 patients in the normal group; positive remodeling accounted for a large proportion(63%) in the BA infarction group, and the stenosis rate was greater than that of the BA non-infarction group(P=0.029), and there was no difference in the degree of plaque enhancement among the groups; According to the topical remodeling group, the plaque area and plaque burden of the positive remodeling group were larger than those of the non-positive remodeling group(P<0.05). The area and diameter of BA in symptomatic BA plaque groups were larger than those in control group(P<0.05), but there was no difference between the two indicators in the symptomatic BA plaque groups. Conclusion: In symptomatic infarct group, positive remodeling was the main local remodeling of BA plaque, and there was general expansion remodeling in BA of symptomatic BA atherosclerosis.

DOI: 10.12117/jccmi.2020.05.003
Objective: To evaluate imaging findings with ultrasound and CT imaging techniques in primary thyroid lymphoma(PTL). Methods: 39 cases of histopathologically proven PTL were gathered for this study. We retrospectively reviewed the sonographic and CT findings of PTL. Results: The mean age of the patients was 65 years old. In sonography, there were 10 cases of diffuse PTL, of which 8 showed enlargement of the thyroid gland and enhancement of post acoustic, 9 showed hypoechogenicity, and 2 showed calcification in lesions; The cases of nodular PTL were 29, of which 19 showed hypoechogenecity and post acoustic enhancement of thyroid, 26 showed reduced echo of lesions, and 3 showed calcification in lesions. 26 of 39 PTL patients had cervical lymph node enlargement. In axial plain CT scans, there were 4 cases of diffuse PTL, 2 cases showed low density, and 1 case showed calcification in lesions; The cases of nodular PTL were 17, 14 cases showed low density, and 2 cases showed calcification in lesion. The above 21 cases showed the same classification types in sonographic and CT findings, of which 8 cases showed cervical lymphadenopathy and 4 cases showed upper mediastinal lymphadenopathy. Of the 14 patients who underwent contrast-enhanced axial CT images, 10 were moderately or mildly enhanced and 9 were homogeneous enhanced. Conclusion: The ultrasonography and CT findings of patients with PTL have corresponding imaging characteristics, and these two can be complementary which help to diagnose PTL.

JIANG Xin-hui, CHEN Jie, WANG Mei-yu, ZHOU Da-wei, XIN Jun, ZHENG Li
DOI: 10.12117/jccmi.2020.05.004
Objective: To explore the diagnostic value of contrast-enhanced ultrasound(CEUS) and two-dimensional ultrasound in the invasiveness of single papillary thyroid microcarcinoma(PTMC) without lymph node metastasis. Methods: A total of 92 patients with single PTMC but without lymph node metastasis confirmed by surgery pathology were recruited as subjects. They were divided into the invasive group(n=13) and non-invasive group(n=79). The differences of the characteristics in two-dimensional ultrasound and CEUS were compared between the two groups. The accuracy of ultrasound and CEUS in the diagnosis of single PTMC without lymph node metastasis was analyzed. The diagnostic efficacy of the combination of the two methods was explored. Results: In the ultrasound characteristics, the proportion of unclear boundary and the rupture of the thyroid capsule echo in the invasive group were higher than those in the non-invasive group(P<0.05). In the CEUS characteristics, the proportion of unclear boundary after enhancement, marginal high enhancement, and enhancement range morphological changes in the invasive group were higher than those in the non-invasive group(P<0.05). The sensitivity, specificity, and accuracy of ultrasound in the diagnosis of single PTMC without lymph node metastasis were 46.15%, 79.75%, and 75.00%, which were lower than CEUS(84.62%, 83.54%, and 83.70%). The combination of ultrasound and CEUS for the diagnosis of invasiveness of single PTMC without lymph node metastasis was the best(AUC=0.929). The best diagnostic point was 0.87. The sensitivity was 100%, and the specificity was 87.74%. The fitting equation was Logit(P)=-2.146+0.585×Two-dimensional ultrasound boundary unclear+2.796×thyroid capsule echo interruption+0.659×enhanced boundary unclear+3.521×enhanced edge height enhancement+5.541×enhanced range morphological change. Conclusion: CEUS combined with two-dimensional ultrasound can better indicate the invasive growth and capsule invasion of single PTMC without lymph node metastasis, and has high application value in judging its invasive ability.

DOI: 10.12117/jccmi.2020.05.005
Objective: To explore the value of conventional ultrasound combined with shear wave elastography(SWE) and ultrasound-guided fine needle aspiration(FNA) cytology in preoperative evaluation of axillary lymph node metastasis in triple-negative breast cancer(TNBC). Methods: Female patients pathologically confirmed to be TNBC in the Guizhou Medical University Affiliated Hospital were recruited as subjects. There were 48 cases in the metastatic group and 57 cases in the reaction group. The detected lymph nodes were subjected to conventional ultrasound and SWE examination, and the ultrasound and SWE multi-parameter indicators of the metastatic group and the reaction group were compared. Ultrasound-guided FNA cytology was performed on suspected axillary lymph nodes to evaluate the diagnostic efficacy of conventional ultrasound, SWE, FNA, and the combination of the three in TNBC axillary lymph nodes. Results: The proportion of patients with metastatic lymph nodes in long to short dimension ratio(L/S)≤2, irregular morphology, missing lymphatic portal, and no lymphatic portal blood flow distribution was higher than that of the reaction group. The mean young’s module(YM) was higher than that of the reaction group, and the difference was statistically significant(both P<0.05). The sensitivity of SWE(87.50%) for the diagnosis of TNBC metastatic axillary lymph nodes was higher than that of conventional ultrasound(79.17%) and FNA(75.00%). The specificity of FNA(94.74%) for the diagnosis of TNBC metastatic axillary lymph nodes was higher than that of SWE(82.46%) and conventional ultrasound(70.18%). The combined fitting equation of conventional ultrasound, SWE and FNA was Logit(P)=-5.301 +5.860×positive FNA+2.259×L/S≤2+1.326×irregular morphology+4.081×missing lymphatic portal+2.729×no lymphatic portal blood flow+0.121×YM average. The sensitivity of the combination was 97.92%, which was higher than that of conventional ultrasound, SWE and FNA respectively. The specificity was 87.72%, which was slightly lower than FNA, but significantly higher than conventional ultrasound and SWE. Conclusion: Conventional ultrasound combined with elastography and ultrasound-guided FNA could improve the accuracy in diagnosis of metastatic axillary lymph node of TNBC.

Objective: Transesophageal echocardiography(TEE) is used to investigate the relationships between left atrial appendage(LAA) function and the recurrence of atrial fibrillation(AF) in patients after radiofrequency ablation. Methods: Sixty-eight AF patients were selected. All patients were examined by TEE, 24~48 h before radiofrequency ablation, 24~48 h after radiofrequency ablation, and 3 months after radiofrequency ablation. According to the recurrence of AF, patients were divided into sinus rhythm group(group A) and AF recurrence group(group B). Having measured the LAA flow filling velocity and emptying velocity(LAA-Fv, LAA-Ev), LAA maximum diameter(LAA-D), LAA maximum length(LAA-L), LAA ejection fraction(LAA-EF) and LAA systolic strain rate(LAA-Ssr). Compared the differences in each group and analyzed the relationships between the function of LAA and the recurrence of AF after radiofrequency ablation by logistic regression. Results: Compared with preoperation: There were no significant changes in LAA-Fv, LAA-Ev, LAA-EF, LAA-Ssr, LAA-L and LAA-D 24~48 h after operation(all P>0.05); 3 months later, LAA-Ev, LAA-Fv, LAA-EF, LAA-Ssr were significantly higher and LAA-D was significantly lower in group A(51 patients)(all P<0.05); LAA-Ev, LAA-Fv, LAA-EF, LAA-Ssr and LAA-D were significantly lower and LAA-D was significantly larger in group B(17 patients)(all P<0.05), and spontaneous echo contrast(SEC) were found in 4 patients’s LAA in group B. Logistic regression analysis showed that LAA-Ev, LAA-Fv, LAA-EF and LAA-Ssr were predictors of AF recurrence. The area under the ROC curve of LAA-Ev, LAA-Fv, LAA-EF and LAA-Ssr were 0.864, 0.817, 0.803 and 0.887. Conclusion: LAA-Ev, LAA-Fv, LAA-EF and LAA-Ssr can be used as predictors of AF recurrence to evaluate the prognosis of patients after radiofrequency ablation, and the predictive effect of LAA-Ssr is better.

DOI: 10.12117/jccmi.2020.05.007
Objective: The aim of the study was to investigate the effect of conservative therapy on pulmonary hypertension(PH) and right ventricular(RV) function in DCM. Methods: This is a retrospective analysis of 60 consecutive DCM patients with evaluation of echocardiographic pulmonary artery systolic pressure(PASP) and right ventricular strain. Results: Compared with patients without PH, patients with PH(PASP≥35 mmHg) had worse left systolic and diastolic function. The ejection fraction increased post-therapy(P=0.046). Reduction of PASP post-therapy was evident in patients with PH(P＜0.001). The tricuspid annular plane systolic excursion(TAPSE) showed no significant difference post-therapy(P=0.102), however, the increase of the RV free wall strain was demonstrated post-therapy with strain imaging(P＜0.001). Compared with TAPSE, the correlation between RV free wall strain and right ventricular ejection fraction(magnetic resonance imaging) was better(r=0.808, P=0.008). Conclusion: The results of this study support the potential of strain imaging to estimate RV function, and adding significant value to conventional echocardiographic measurements.

DOI: 10.12117/jccmi.2020.05.010
Objective: To investigate the value of T2WI grayscale ratio in the differential diagnosis of small clear cell renal cell carcinoma(CCRCC) and angiomyolipoma with minimal fat(AMLmf). Methods: T2WI data of 46 cases surgical which pathological comfirmed CCRCC and 32 cases of proven 35 AMLmf the diameter ≤4.0 cm were restrospectively analyzed. The grayscale value of renal tumor to kidney cortex and tumor to spleen were measured and calculated by RADinfo Reading System. The threshold value of the optimal ratio to identify CCRCC and AMLmf was obtained through the ROC curve. Results:  In 46 CCRCC and 35 AMLmf, the tumor/kidney ratio and tumor/spleen ratio were 1.021±0.206 and 0.710±0.159(t=7.420, P<0.001), 1.634±0.331 and 1.140±0.272(t=3.889, P<0.001), respectively. The area under the curves and optimal threshold of tumor/kidney ratio and tumor/spleen ratio in the identification of CCRCC and CCRCC respectively were 0.891 and 0.904, 0.817 and 1.123, respectively. And the corresponding sensitivity and specificity were 76.1% and 91.4%, 87.0% and 71.4%. While these ratios were increasing, the sensitivity to diagnose CCRCC decreases and the specificity increases. In combination with tumor/kidney ratio and tumor/spleen ratio, the sensitivity and specificity were 69.6% and 94.3%. Conclusion: T2WI grayscale ratio can identify CCRCC and AMLmf objectively, accurately and quantitatively. The tumor/kidney ratio has a high specificity, and the tumor/spleen ratio has a high sensitivity. The combination of the two ratios has higher specificity, which reduce the incidence of misdiagnosis.

DOI: 10.12117/jccmi.2020.05.011
Objective: The prognostic impact of total metabolic tumor volume(TMTV) measured on pretreatment 18F-FDG PET/CT was investigated in patients with diffuse large B-cell lymphoma(DLBCL). Methods: A total of 65 consecutive patients with DLBCL who received Rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone chemotherapy(R-CHOP) as first-line treatment and baseline FDG PET/CT were retrospectively evaluated. Receiver operating characteristic curve analysis was used to determine the optimal cut-off values for the metabolic parameters. The relationships between study variables and patient survival were tested using Cox regression analysis. Patient survival rates were derived from Kaplan-Meier curves and compared by using the log-rank test. Results: In patients with a low TMTV(<146 cm3), the 2-year progression free survival(PFS) rate was 43.1% and the overall survival(OS) rate was 45.3%, in contrast to 5.2% and 15.3%, respectively, in those with a high TMTV(≥146 cm3). Conclusions: TMTV of 18F-FDG PET/CT could be used as an important prognostic indicator for DLBCL.

WANG Yu, SUN Xue
DOI: 10.12117/jccmi.2020.05.012
Objective: To explore the feasibility and application value of real-time Bi-plane technique for the visualization of fetal interventricular septum(IVS). Methods: Using real-time Bi-plane technique to observe fetal IVS in 150 normal fetuses and 29 abnormal fetuses(including 21 cases of isolated VSD and 8 cases of AVSD). The fetal intact IVS can be demonstrated by displaying the apical four-chamber view or the bottom of four-chamber view, then putting the reference line across the IVS when using real-time Bi-plane technique. The integrity of IVS was then assessed. In addition, fetal cardiac volumes were acquired and analyzed by STIC technique to obtain the reconstructed image of IVS in all the normal and abnormal fetuses. Results: Compared with STIC modality, the Bi-plane technique showed a significantly higher visualization rate of IVS for the normal(98.7% vs. 83.3%, P<0.01) and abnormal fetuses (96.6% vs. 79.3%, P<0.01). At the same time, the time needed to obtain the plane for IVS of the Bi-plane technique was significantly shorter than STIC modality((15.5±5.8) s vs. (58.1±13.3) s, P<0.01). Conclusion: Real-time Bi-plane technique is a simple and time-saving method for the real-time assessment of the fetal intact IVS, which can be used as an important auxiliary examination of conventional two-dimensional fetal echocardiography and thus has important clinical value.

DING Chun-xia1, QU Ruo-wei2, YIN Ying1
DOI: 10.12117/jccmi.2020.05.013
Objective: Automatic recognition and classification on fetal ultrasound image is significant to make doctors’ work efficiency. Method: Being different from traditional automatic classification method whose images should be segmented in detail, feature extracted manually and then classified, we proposed a deep convolutional neural network(CNN) based fetal thalamus plane ultrasound image recognition method. First, the images were pre-processed, such as image enhancement; then, we proposed an improved CNN algorithm. Result: This algorithm avoids the complex pre-processing of two-dimensional ultrasound image, and can input the original two-dimensional ultrasound image directly. It has strong capacity of adaption and generalization. The experimental results show that the recognition accuracy of this method can reach 94.81%. Conclusion: The proposed model provides a new reference for automatic medical image recognition technology.

GE Wen, SONG Xiu-feng, PAN Si-lin
DOI: 10.12117/jccmi.2020.05.014
Objective: We analyzed the imaging manifestations of hemimegalencephaly(HME) in children and fetuses, in order to improve the understanding of HME, especially in fetuses, and to reduce birth defects. Methods: Eleven cases of HME confirmed by clinical and MRI from September 2011 to December 2018 were retrospectively reviewed, including 3 fetuses and 8 postnatal cases. Of the 11 patients, 8 patients underwent MRI scan only, 2 cases underwent CT and MRI examination, and 1 underwent CT examination only. Surgical treatment was performed in 2 cases. Results: The HME of 8 postnatal cases were 4 involved in the left hemisphere and 4 in the right hemisphere; all the cases had thicken cortex on the affected side, wider or irregular gyrus, pachygyria or polymicrogyria like gyrus pattern and widened and morphologically abnormal ventricles of the affected side. The midline structure shifted and crooked, and abnormal enlargement of deep gray matter nuclei in 7 cases, white matter showed T2WI hypointensity in 6 cases, gliosis in 3 cases, calcification in 1 case, heterotopic subependymal gray matter in 1 case, involvement of ipsilateral cerebellar hemisphere in 1 case, and the thick of soft tissue in the ipsilateral head and face increased. Besides, there was one case with Chiari type I. Fetal HME, prenatal ultrasound showed unilateral ventricular enlargement, and prenatal MRI all gave definite diagnosis. In all 3 cases, the biparietal diameter was larger than the normal one in the gestational week. Increased cranial cavity, cortical thickness, irregular ventricular enlargement, discrepancy between sulcus gyrus development and gestational week, and low signal intensity of T2 and T2-like sequence were found. Two cases were associated with obvious pachygyria and polymicrogyria like gyrus pattern. Conclusion: The MRI manifestations of HME are characterized by diffuse enlargement of the hemisphere, enlargement of the lateral ventricle, thickening of the cerebral cortex, loss of normal grey and white matter signals, and hamartoma-like changes. The MRI manifestations in fetal HME is similar to that of children. In addition, it is often accompanied by biparietal diameter greater than the nomal one gestational weeks, and sulcus development inconsistent with that in gestational weeks. These can be well assisted by ultrasonography to make a definite diagnosis and reduce birth defects.

DOI: 10.12117/jccmi.2020.05.015
Objective: To investigate the expression of 18F-FDG PET/CT in patients with adult-onset Still’s disease (AOSD) and its role in disease activity. Methods: 46 patients who was diagnosed as AOSD were selected and underwent 18F-FDG PET/CT. The clinical manifestations, laboratory examination and characteristics of PET/CT were collected. Then the correlation between SUV intensity of liver, spleen, bone marrow, lymph node and laboratory indexes, system scores were analyzed. Results: 18F-FDG accumulation occurred mainly in bone marrow(100%, SUV intensity: 2.00±0.66), Spleen(96%, SUV intensity:1.70±0.54) and lymph nodes(98%, SUV intensity: 2.67±1.38). In addition, 18F-FDG uptake can also occur in the pericardial pleural, parotid gland, thyroid, skin, joint esophagus and cardia. SUV intensity of bone marrow was significantly correlated with systemic score, ESR, C-reactive protein, WBC and NEU%(r=0.445, 0.376, 0.323, 0.439, 0.524, P<0.05). SUV intensity of spleen was significantly correlated with system score and LDH(r=0.424, 0.347, P<0.05). SUV intensity of lymph node was significantly correlated with disease system score(r=0.356, P<0.05). Conclusion: 18F-FDG accumulation occurred mainly in bone marrow, spleen and lymph nodes. 18F-FDG PET/CT is helpful for the differential diagnosis and monitoring of disease activity.
