GUO Jia-bao;DONG Bei-li
DOI:
Objective: To discuss the change of endocardial rotation angle and epicardial rotation angle in different phases by two-dimensional speckle tracking technology(STI) on patients with chronic kidney disease(CKD), we can evaluate cardiac function in patients with different stages of CKD from two aspects of time and space, and know its initial change in different planes and phases at the same time. Methods: Fifty patients with CKD were included. Among them stage 1～3 were assigned as CKD group 1, stage 4, 5 were assigned as CKD group 2. Each group included 25 cases. Twenty-five normal patients were in control group. The mean rotation angle of endocardium and epicardium of the three groups were obtained at each phase using STI. Results: ①During isovolumic contraction period, the rotation angle of endocardium and epicardium in both the basal and apical cardiac planes in CKD 1 and CKD 2 had no significant change. ②During ejection period, the rotation angle of endocardium in both the basal and apical cardiac planes in CKD 1 and CKD 2 were decreased; The rotation angle of epicardium in both basal and apical cardiac planes in CKD 2 were decreased. ③At the end of isovolumic diastole, the rate of endocardial untwisting in both basal and apical planes in CKD 1 and CKD 2 reduced significantly; The rate of epicardial untwisting in basal plane in CKD 1 and CKD 2 reduced at the same time. Conclusions: STI has a potential ability to evaluate when and where the heart function have changed first in patients with CKD by measuring the rotation of endocardium and epicardium of left ventricle．

DOI:
Objective: To discuss the value of contrast-enhanced magnetic resonance cholangiography(CE-MRC) using gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA) in patients with liver cirrhosis. Methods: The dynamic scan and CE-MRC in hepatobiliary phase were performed in 53 patients with liver cirrhosis and 18 normal adults, the image quality of CE-MRC at 5, 10, 15, 20 and 25 minutes in hepatobiliary phase were evaluated, the relationship between signal intensity of common bile ducts and serum total bilirubin level, albumin level and prothrombim time were analyzed. The differences between CE-MRC and MRCP were compared. Results: CE-MRC allowed the visualization of most parts of biliary duct at 15 minutes after administration of Gd-EOB-DTPA in normal adults. The visualization of biliary ducts were delayed in patients with liver cirrohsis, especially in cases with Child-Pugh B and C. There were no differences of signal intensity of common bile ducts at 25 minutes delayed between the normal adults and patients with Child-Pugh A(P=0.570), while there were differences between normal adults and Child-Pugh B(P=0.002), between Child-Pugh A and Child-Pugh B(P=0.000). In patients with liver cirrhosis, the correlation coefficient between signal intensity of common bile ducts and prothrombin time was -0.57, CE-MRC and MRCP showed 79% and 32% of the cystic ducts respectively(χ2=23.891, P=0.000) and had the similar ability for displaying the second order division ducts, bilateral hepatic ducts and common bile ducts(P＞0.05). Conclusion: It was suitable that CE-MRC were performed at 25 minutes after contrast administration in patients with liver cirrhosis. The liver funcion affected the time of visualization and signal intensity of bile ducts, CE-MRC had the advantage for detecting the cystic ducts than MRCP. CE-MRC combined with MRCP allowed evaluation for structure and function of biliary system effectively.

DOI:
Objective: To investigate the application of MR diffusion-weighted image(DWI) in evaluating the early therapeutic effect of local thermal ablation for hepatocellular carcinoma(HCC). Methods: Twenty-one nodules histologically proved HCC in 21 patients were enrolled. All patients received DWI with different b values before and immediately after(within 24 hours) local thermal ablation. The differences of ADC values with the same b values between pre- and post-ablation were measured. Receiver operating characteristic(ROC) curve analysis was performed for the comparison of viable tumor and necrostic tissue. Results: The ADC value post-ablation increased significantly than pre-ablation of each b value(P＜0.01). The ADC value was an effective parameter for identifying necrotic tissue: when b value was 1 000 s/mm2, a threshold value of 1.09× 10-3 mm2/s permitted 89.5% sensitivity and 63.2% specificity and a threshold value of 1.26×10-3 mm2/s permitted 52.6% sensitivity and 89.5% specificity. Conclusion: DWI has the capacity of evaluating early therapeutic effect of thermal ablation for HCC.

DOI:
Objective: To explore the CT imaging features of sclerosing stromal tumors(SST) of ovary, in order to improve diagnosis. Methods: CT manifestations of 12 cases with SST of ovary confirmed by pathology were analyzed retrospectively. Results: Among the 12 cases with SST of ovary, 7 of them located in the left ovary and 5 cases right. The tumors size varied from 3.6～12.1 cm in the largest diameter. Unenhanced CT scans showed mixed density mass with cystic and solid density, 10 cases(83%) were predominantly solid-density tumors, and 2 cases(17%) predominantly cystic-density tumor. Calcifications were seen in 4 cases(33%). Contrast-enhanced CT scans showed heterogeneous enhancement significantly in all cases. The features were as follows: According to the range of enhancement: 12 cases(100%) solid components appeared as progressive enhancement, similar to “hepatic cavernous hemangioma”, but the cystic components has no enhancement in the whole course. According to the mode of enhancement: ①Early-fast sustained enhancement: the curve of enhancement of the solid components in 7 cases(58%) appeared as peak-shape, but the cystic components has no enhancement in the whole course. Two cases showed dilated tortuous arteries enhanced obviously around the mass in the arterial phase. ②Gradual increase enhancement:In 5 cases(42%) the curve of enhancement of the solid components appeared as straight line shape, but the cystic components has no enhancement in the whole course. Two cases showed a multiloculated cystic mass with irregularly thickened septae and tumor wall. Conclusion: SST of ovary has some specific CT manifestations, CT examination combined with clinical manifestations is helpful for the diagnosis of SST of ovary.

GUO Min;ZHU Qi
DOI:
Objective: To confirm the suitable index and critical value in diagnosing the fetal first degree atrioventricular block. Methods: Sixty-two pregnant women in third trimester(≥38 week) of our out-patient clinic were erolled. TDI-derived AV intervals were measured as the intervals from atrial contraction(Aa) to isovolumic contraction(IV) and from Aa to ventricular systole(Sa). Their neonatal ECG were performed and the correlation between the neonatal PR intervals and fetal TDI values was analysed by linear regression. Receiver operator characteristic(ROC) curve was established to compare the diagnostic value of Aa-IV and Aa-Sa and to determine the most suitable critical value to screen the fetal first degree atrioventricular block. Results: Aa-IV correlated significantly better with neonatal PR intervals than did Aa-Sa. The ROC showed secondary diagnostic value of Aa-IV and only little diagnostic value of Aa-Sa. The point(Aa-IV=93.7 ms) of Aa-IV curve with sensitivity 100% and specificity 51%, was confirm to screen the first degree atrioventricular block. Conclutions: TDI-derived Aa-IV can assess the fetal atrioventricular time interval more accurately than did Aa-Sa. The point(Aa-IV=93.7 ms) should be used as the critical value to screen the fetal first degree atrioventricular block.

WU Bin;JIN Biao;YIN Sheng-li
DOI:
Objective: To explore whether there is any effect of the size of region of interest(ROI) on diffusion weighted imaging(DWI) of the vertebral lesions on the measurement of ADC value, thus influencing the differential diagnosis between benign and malignant lesions. Methods: Sixty patients with 92 benign or malignant lesions of the vertebral body confirmed by clinical followed up and long term radiographic review were collected and analyzed. Conventional MRI and DWI were performed on each patient. Two different sizes of ROIs were placed on the center of the lesion in each patient. The signal intensity of the lesion and ADC value were measured and statistically analyzed. Results: The ADC value of different ROI sizes on the same lesion had statistical significance(P<0.05). Moreover, the mean ADC value of smaller ROI size was higher than that of bigger size ROI. The mean ADC value in benign and malignant vertebral lesions in a small ROI or in a large ROI had statistical significance(P<0.05). Conclusion: It is concluded that the size of ROI could affect ADC value in vertebral lesions, and further affect the differential diagnosis between benign and malignant vertebral lesions.
