DOI:
Objective: To study the clinical application of FA and ADC values in brain AIDS-associated infection. Methods: 22 subjects who suffered from AIDS(12 brain tuberculosis and 10 toxoplasmosis) were recruited to perfprm routine MRI, T1WI-CE and DTI sequences. Morphological characteristics of lesions were observed. ADC and FA values of the lesional solid areas, edematous areas and the contralateral normal areas were measured. The diagnostic efficiency of the two values were analyzed by ROC curve. Results: Significant differences of ADC and FA values were observed among the three regions between subjects with brain tuberculosis and those with toxoplasmosis(P<0.05). Compared with the contralateral normal areas, ADC and FA values of the solid areas and edematous areas in two groups showed significant differences(P<0.05). For lesional solid and edematous areas, FA values and ADC values in the the groups showed significant differences. FA values of the solid area in two groups showed significant difference(P<0.05). ROC curves showed the AUC of FA value was larger than that of ADC value(0.932 vs 0.715, respectively, P<0.05). Conclusion: DTI helps to diagnose brain tuberculosis or toxoplasmosis in AIDS patients and provides evidences for medical treatment.

DOI:
Objective: To evaluate the role of diffusion tensor imaging(DTI) in evaluating the corticspinal tract(CST) damage and predicting neurological motor function outcome for patients with basal ganglia hemorrhage. Methods: Thirty-six patients with intracerebral hemorrhage in basal ganglia underwent 3.0T MR scanning with routine sequences and DTI sequence in the period of 8 to 15 days and 4 to 6 months after onset. A region-of-interest-based analysis was performed for mean FA values within the cerebral peduncle. According to the extent of the CST damage on DTT maps, group A(CST undestroyed), group B(CST was interrupted around the hematoma) and group C(CST did not reach the hematoma) were classified. The ratios of FA values in the affected and unaffected hemisphere(rFA) within the cerebral peduncle were compared between the two groups and two examinations(the first time and follow-up examinations). The correlations of rFA with modified Rankin Scale (mRS) scores and the motor component of the functional independence measure(FIMm) at 4~6 months after onset were analysed. Results: In the period of 8 to 15 days, the motor function of type C was worse than that of type A or B(P<0.05), and motor function of type A was better than that of type C(P<0.05). In the period of 4 to 6 months, of 16 type A, only 2 changed to type B; of 12 type B, 11 changed to type A and 1 changed to type C; of 8 type C, 2 changed to type A, 1 changed to type B and 5 remained the same. There was statistically significant difference(P<0.05) in FA values between the affected and unaffected cerebral peduncle at two DTTs. There was statistically significant difference in FA values of the affected between the two examinations(P<0.05) and unaffected cerebral peduncle between the two examinations(P<0.05). The rFA values from the cerebral peduncle were correlated with mRS scores(P<0.05), but not correlated with FIMm scores at two DTTs. At the first DTT, a weak correlation was revealed between rFA and FIMm scores in group A(P＜0.05) and a strong correlation between rFA and FIMm scores in group B(P＜0.05). At the second DTT, strong correlation was revealed between rFA and mRS scores in group A(P＜0.05). Conclusions: For basal ganglia hemorrhage, rFA values from the cerebral peduncle could predict long-term neurological motor function outcome and CST damage.

DOI:
Objective: To investigate the altered activity of working memory related brain regions in patients with type 2 diabetes mellitus(T2DM), and the possible neural mechanisms. Methods: Twenty-one T2DM patients and 21 normal subjects received functional MRI(fMRI) scanning with a 1-back working memory(WM) task in this study. The fMRI data were preprocessed using SPM8. One-sample t-test and two-sample t-test were used to analyze the WM related brain activity within and between groups, respectively. Statistical thresholds were set at P<0.01(AlphaSim correction). BOLD percent signal change(PSC) of regions with intergroup difference was calculated and the correlation analyses were performed between the PSC and the response time(RT) of 1-back task and glycosylated hemoglobin level. Results: The fasting plasma glucose and glycosylated hemoglobin level were significantly higher in T2DM patients than controls(P<0.001), and accuracy of 1-back task was significantly lower than that of controls(P<0.05). Compared to the controls, T2DM patients showed significantly higher activation in the bilateral dorsolateral and ventrolateral prefrontal cortex and the right posterior parietal cortex(P<0.01), and significantly lower deactivation in the left inferior parietal lobule and the right superior frontal gyrus(P<0.01). Significant negative correlations were found between the PSC of the bilateral dorsolateral prefrontal cortex and the RT in T2DM group(P<0.05). Conclusion: Hyperactivation of the WM related brain regions may have a limited compensation for the decreased WM behavior in T2DM patients.

DOI:
Objective: To investigate CT findings of parotid gland in Sj?觟gren’s syndrome(SS). Methods: Thirteen cases of clinical confirmed SS patients were enrolled and underwent parotid gland CT scan. Fourteen cases of patients who underwent neck CT scan and have no parotid disease were selected as the control group. The imaging features assessed mainly included heterogeneity, diffuse fatty tissue deposition, density of parotid gland parenchyma and calcification. Independent sample t test was used in comparison of CT values between the two groups. Results: Parotid glands of control group showed even low density. However, it was uneven for bilateral parotid glands with diffuse fatty tissue infiltration. The density of parotid gland parenchyma increased. 10 parotid glands of 5 patients showed diffuse multiple punctate calcification. CT value of parotid gland parenchyma[(-3.42±24.11)HU and (-24.11±20.32)HU, respectively(P=0.001)] showed statistical differences between SS and control group. Conclusion: Diffuse infiltration of adipose tissue and increased parotid gland density are characteristic CT manifestations of parotid gland in SS patients. Characteristic diffuse punctate calcification can also be seen. CT can be used as a screening of SS.

LI Hong;LI De-hua;HU Bo
DOI:
Objective: To investigate the expression of Ki67 and p53 in breast cancer, and their correlation with color Doppler ultrasound features. Methods: 135 cases of breast cancer confirmed by pathology were retrospectively enrolled for the color Doppler ultrasound features, including tumor size, edge, shape, distribution and morphology of calcification, flowing image grading, lymph node metastasis and surrounding tissues invasion. The expression of Ki67 and p53 was detected with immunohistochemical methods and their correlations with color Doppler ultrasound features were analyzed. Results: The positive rate of Ki67 and p53 in breast cancer tissue were 64.4%(87/135) and 51.1%(69/135) respectively. The expression of Ki67 and p53 showed no correlation with tumor size and tumor edge(P>0.05), but correlated significantly with flowing image grading, lymph node metastasis and surrounding tissues invasion(P<0.05). The expression of Ki67 had significant correlations with tumor morphology and calcification(P<0.05), but no correlation with the distribution of calcification(P>0.05). The expression of p53 had no correlation with tumor morphology and shape of calcification(P>0.05), but significant correlation with the distribution of calcification(P<0.05). The expressions of Ki67 and p53 were positively correlated(r=0.617, P<0.05). Conclusion: There were correlations between ultrasound features and expression of Ki67 and p53 in breast cancer. Color Doppler ultrasound features may play a potential role in clinical application of non-surgical treatment and presurgical assessment of breast cancer.

DOI:
Objective: To investigate the clinical value of gated SPECT myocardial perfusion imaging on cardiac resynchronization therapy(CRT) and evaluate their prognosis in patients with chronic heart failure(CHF). Methods: Twenty one patients with CHF in 2012 January to 2014 June were assigned to CRT, and underwent gated SPECT myocardial perfusion imaging (GSMPI) before operation. Functional parameters including phase histogram bandwidth, phase standard deviation, left ventricular ejection function, end diastolic volume, summed rest scores and scar size were acquired by imaging. All patients underwent a second-time cardiac ultrasonography at the sixth month after operation. Effective therapy was considered when left ventricular end diastolic diameter decreased, LVEF increased, and no hospitalization records existed within half a year. Then, the patients were divided into effective and ineffective groups. The differences between the functional parameters of the two groups were compared, the predictive value for the efficacy of CRT was analyzed, and the latest systolic area in the left ventricule was recorded. Results: Fifteen cases(71.4%) were effective after CRT, and 6 cases(28.6%) were irresponsive. All parameters between the two groups showed significant differences(P<0.05), and PSD and PHB were the most significant(P<0.01). The latest systolic area of the left ventricle was located in the apex, the anterior wall and the septal wall in 10 patients’(47.63%), in the inferior wall in 6 patients(28.6%), and in the lateral wall in 5 patients(23.8%). Conclusion: GSMPI can provide “one-stop” multiple functional parameters, which can be used to guide CRT electrode implantation and predict curative effect. PSD and PSW might have a higher predictive value.

DOI:
Objective: To analyze MRI features of placental invasion and evaluate the clinical value of MR topography classification. Method: Records from December 2009 to May 2014 were reviewed to identify the accuracy of MRI in the diagnosis of placental invasion in the patients with a diagnosis of placenta previa and suspected placental invasion by ultrasound. Sensitivity, specificity, PPV and NPV were calculated on each MRI feature of placental invasion including myometrial attenuation, loss of placental-myometrial interface, T2WI dark bands and outward protruding of the uterus. All final diagnosis was based on surgical and pathological findings. MR topography classification was carried out on confirmed cases according to the topography of placental invasion. Over 50%, no more than 50% of uterine axial circumference and parametrial invasion were categorized as invasion of category A, B and C. Success rates of conservative treatment were compared by χ2 test between each category. Result: Of the 69 suspected cases, 46 had confirmed placenta invasion. MRI accurately predicted placenta invasion in 43 cases(sensitivity 93.48%) and 21 cases were correctly ruled out(specificity 91.30%). Loss of placental-myometrial interface was of the highest sensitivity and NPV(95.56%, 90.0%), followed by myometrial attenuation. T2WI dark bands was of high PPV(90.01%), and outward protruding of the uterus was of the highest specificity and PPV(100%). Success rates of conservative treatment were 100%(category A), 23.08%(category B) and 12.5%(category C) with statistical difference(P<0.05). Conclusion: Diagnostic accuracy of MRI is high in evaluating placental invasion. Loss of placental-myometrial interface is the prime feature in assessment. MR topography classification helps to determine conservative treatment.

GAO Jin;ZHOU Han;OUYANG Yu;LIU Hong;DAI Mao-liang;WU Xiao-yun
DOI:
Objective: To discuss the influence of different regions of interest(ROI) on the time-intensity curve(TIC) and its value during dynamic contrast-enhanced MRI(DCE-MRI). Method: Prostate DCE-MRI was performed on all the 99 patients. There were 118 lesions in the peripheral zone, including 55 benign lesions and 63 prostate cancers. On dynamic contrast-enhanced MRI, the TIC of a large ROI(20~150 mm2) on the central layers of the foci and 13 small ROIs(6.6 mm2) scattering inside the foci were obtained. The difference between the TICs of the large and small ROIs in the benign and malignant prostate foci was compared. Two protocols were adopted to classify the TIC of the foci, and then PI-RADS score to DCE-MRI was carried out respectively. Protocol 1: The type of curve was big ROI curve. Protocol 2: The type of curve was type 3 curve if there was such a curve in any small ROI. Otherwise, it was regarded as a large ROI curve. Result: The median number of small ROIs with the type of big ROI curve in the foci was 12 for the benign lesions and 10 for the prostate cancer. The median test result was P=0.003. For diagnosis of prostate cancer, the sensibility and specificity of Protocol 1 were 76.36% and 90.48%, while the sensibility and specificity of Protocol 2 were 87.27% and 85.71%(P=0.031 and P=0.250 respectively). Conclusion: Enhancement at different ROIs of the foci of prostate cancer did not go all the same way. It is helpful for the diagnosis of prostate cancer in the peripheral zone to adopt small ROIs to seek type 3 curve.

FENG Jin;LOU Lu-xin;ZHANG Lian-na;YANG Fang;CHENG Xiao-guang
DOI:
Objective: To find a semi-quantitative bone imaging method by comparison with MRI in order to measure bone invasion of limb osteosarcoma accurately. Methods: 23 patients diagnosed with osteosarcoma by histology were included. Preoperative whole body bone scan and partial magnetic resonance imagings(MRI) were analyzed retrospectively. Threshold method of radioactive count changing-rate on bone scan was designed. The radioactive count changing-rate R=(T-NT)/NT×100% was converted into T=R×0.01×NT+NT. By assuming multiple R values, different T values of tumor boundary were obtained. Visual measurements on bone scintigraphy and MRI T1WI were compared with pathological boundaries as the gold standard. Paired t-test was used to analyze the accuracy. The intraclass correlation coefficient was used to evaluate the repeatability in two observers and two times of measurements. Results: There were significant differences between bone scanning visual method and pathologic measurements(t=-3.041, P=0.006<0.01). There was no significant difference between bone scan threshold method and pathologic range, with radioactive count changing-rate R=80%(t=-1.519, P=0.143>0.05), R=100% (t=-0.642, P=0.527>0.05), R=120%(t=0.192, P=0.850>0.05）, R=140%(t=1.178, P=0.252>0.05). When R=100% and 120%, average difference was the minimum． The differences between MRI T1WI measurements and pathologic measurements showed no difference(t=-3.041, P=0.006<0.01). In cases with varied signal intensities on MRI, the measurements of MRI and pathology were matched in the plane which was the closest to bone scan semi-quantitative method(R=100% and R=120%). In bone scanning visual method, there was significant difference of osteosarcoma extents between two different measurers(P<0.05), and there was no significant difference between two times of the same observer(P>0.05). In bone scan threshold method, measurements of two observers and two different times of the same observer showed high consistency(ICC>0.900). Conclusion: MRI is dominant in the evaluation of intramedullary invasion in osteosarcoma. In assessing range of far-articular bone invasion, threshold method of radioactive count changing-rate on bone scan is more objective and accurate than visual method. Bone scintigraphy helps to determine the measurement plane on MRI T1WI in cases with varied signal intensities.

WANG Jian-wei;XU Xiao-quan;WANG De-hang;ZOU Yue-fen;SHI Yin;XU Lei;SHI Hai-bin
DOI:
Objective: To evaluate the application value of T2 mapping technique in the assessment of lumbar disc degeneration. Materials and Methods: 33 cases diagnosed as lumbar disc degeneration underwent lumbar routine magnetic resonance imaging and T2 mapping scanning. All their intervertebral discs(IVDs) were graded by Pfirrmann scale. T2 values of the anterior annulus fibrosus(AAF), the nucleus pulposus(NP) and the posterior annulus fibrosus(PAF) were measured manually on the sagittal T2 map. ANOVA analysis was used to compare the differences of T2 values at the AAF, NP and PAF of degenerated IVD with different Pfirrmann grades. The correlation between T2 values and Pfirrmann grades of the IVDs was evaluated by Spearman analysis. Results: No significant differences were found about T2 values of AAF or PAF at different Pfirrmann grades(AAF, P=0.233; PAF, P=0.906), while significant difference was found about T2 values of NP at different Pfirrmann grades(P=0.000). After multiple comparisons, T2 values of Pfirrmann Ⅱ~Ⅲ and Pfirrmann Ⅲ~Ⅳ showed statistical differences(Pfirrmann Ⅱ~Ⅲ, P=0.000; Pfirrmann Ⅲ~Ⅳ, P=0.008). But T2 values of Pfirrmann Ⅰ~Ⅱ and Pfirrmann Ⅲ~Ⅴ had no statistical differences(Pfirrmann Ⅰ~Ⅱ, P=0.357; Pfirrmann Ⅳ~Ⅴ, P=0.489). Significant negative correlation was found between T2 values of NP and Pfirrmann grades (r=-0.765, P=0.000), while only poor correlation was found between T2 values of AAF and Pfirrmann grades(r=-0.166, P=0.036), and no correlation between T2 values of PAF and Pfirrmann grades(r=0.051, P=0.521). Conclusion: T2 mapping technique could quantitatively demonstrate the differences of T2 values between the different structures of IVDs at different Pfirrmann grades, which provided evidence for clinical quantitative diagnosis of the IVD degeneration.

HE Chun-ni;LI Jun
DOI:
Objective: To explore changes of metabolite levels in the occipital lobe and cerebellum for patients with vertebral-basilar insufficiency(VBI) by magnetic resonance spectroscopy(MRS). Methods: The study group consisted of nine patients diagnosed with VBI by clinical and MRA methods. Seven age-matched healthy subjects were recruited in the control group. MRS by multi-voxel chemical shift imaging was performed. The metabolite ratios of occipital lobe and cerebellum involving NAA/Cr, NAA/Cr2, Cho/Cr, Cho/Cr2 and NAA/Cho were estimated. The Mann-Whitney U test was performed to compare the differences between the two groups. The appearance of Lac peak was noted between two groups and Fisher's exact test was performed to compare the differences. Results: There was no statistical difference for the ratios of NAA/Cr2, Cho/Cr2, NAA/Cho in occipital lobe(P>0.05). The ratio of NAA/Cr in cerebellum with VBI was found decreased compared to normal control subjects(0.83±0.15 vs 0.98±0.14, P=0.043). There was no statistical difference for the ratios of NAA/Cr2, Cho/Cr2, NAA/Cho in cerebellum(P>0.05). Lac peaks were detected in the cerebellum in four VBI cases and in the occipital lobe in one VBI case. and no Lac peak was detected in the control group with statisticaldifference(P=0.034). Conclusion: MRS is a useful tool for evaluation of major changes of metabolite levels in brain and may contribute to evaluate the damage caused by VBI biochemically.
