LI Ke;JIN Zhen;ZHANG Lei;ZENG Ya-wei;ZHANG Xiao-feng;WU Qiao
DOI:
Objective: To explore the recovery mechanisms of Broca aphasia after cerebral stroke. Methods: Six patients of Broca aphasia from acute stroke were scanned twice in a 3T MR system with block-designed BOLD fMRI sequences, undergoing picture-naming task. Functional images were processed by using SPM5 software with general linear model(GLM) to generate activations. The distributions, dimensions and intensities of activations were compared and analyzed. Results: After aphasia, the language-associated areas in the left hemisphere were shown partially activated. In 3 cases, the activations of Broca’s area in the right hemisphere were shown. After aphasia recovery, the activation number, dimension and intensity in the left hemisphere increased. The activations of Broca’s area in the left hemisphere were shown in all the patients. The activations of Broca’s area in the right hemisphere decreased. Conclusion: Bilateral hemispheres synchronously participate in the process of language recovery. The recovery of language function depends on the functional transfer of right hemisphere at acute stage, and the functional reorganization has more important effect from the left hemisphere at chronic stage.

157 Value of real-time ultrasound elastography in assessment of cervical lymph nodes
TENG Deng-ke;WANG Hui;SUN Li-na;LIN Yuan-qiang;SUI Guo-qing
DOI:
Objective: Comparing with conventional ultrasound, to validate the value of ultrasound elastography(UE) in differentiating benign and malignant cervical lymph node(LN). Methods: B-mode ultrasound(B-US), color Doppler flow image(CDFI) and UE were performed for 99 lymph nodes of 74 patients and compared with final histological pathology obtained by ultrasound guided core needle biopsy. Results: With the cutoff point of strain ratio(SR) ≥1.78 for malignancy, UE was the most valuable in differential diagnosis of benign and malignant cervical lymph nodes. The sensitivity, specificity and accuracy were 98.3%，65.9% and 84.8%. The sensitivity, specificity, accuracy of B-US and CDFI were 55.2%, 82.9%, 66.7% and 72.4%, 75.6%, 73.7%. Compared with B-US, the sensitivity, accuracy and area under the ROC curve(AUC) of UE were statistically higher. Compared with CDFI, UE had a statistically higher sensitivity, but not the AUC. Conclusion: SR with the cutoff point of 1.78 is better than B-US in the differential diagnosis of benign and malignant cervical lymph nodes. As conventional ultrasound, UE is expected to be an important technique in the differential diagnosis of benign and malignant cervical lymph nodes.

HU Bin;HU Mei;WANG Yan
DOI:
Objective: To study the radioanatomic parameters of coronary sinus using 64-row CT for guiding catheter implantation and design. Methods: One hundred and two cases of patients with paroxysmal atrial fibrillation underwent 64-row cardiac enhanced CT as a routine examination before ablation. Advantage Workstation 4.3(GE Medical System) was used for multi-slice analysis and reconstruction of three-dimensional cardiac image of interest. The diameter of aorta, the height of the thoracic vertebrae, the orientation of coronary sinus orifice(CSO), the diameter of CSO, the height of CSO from the inferior margin of the heart. The relation of CSO diameter and the height of CSO to the height of the body, body weight, the location of thoracic vertebrae, and the cardiac silhouette were analyzed. Results: CSO pointed upward(27.4°±10.2° to the axial plane), rightward and anterior (31.1°±11.4° to the sagittal plane). The minimum diameter of CSO was 12.4 mm×4.3 mm and the maximum diameter was 37.3 mm×21 mm. The terminal diameter of CSO was (8.9±2.7) mm. The location of CSO was 4.8±0.7 times the height of vertebrae inferior to the sternal angle plane and was about (27.8±8.5) mm(1.2 vertebrae height) above the bottom of the heart. There was a better anatomical relation between the CSO and heart shape angular correlation. CSO in transverse heart was significantly lower. Conclusions: CSO opens upward and points rightward and anterior. The diameter of orifice has large variation. The location of CSO is more related to the horizontal degree of the heart and about 1.2 times the vertebrae height above the bottom of the heart.

WANG Shuai;QIN Shi-cheng;ZHANG Rui-fang
DOI:
Objective: This study was performed to evaluate the characteristics of left ventricular systolic longitudinal strain(LS) in healthy children and its relationship with age using three-dimensional speckle tracking(3DT). Methods: One hundred and twenty-six healthy subjects aged from 3 days to 15 years were divided into 5 groups: group A infants(3 days～3 years old), group B pre school age children(3～5 years old), group C school age children(6～9 years old), group D preadolescent(10～12 years old) and group E adolescent age(13～15 years old). The dynamic images of apical two and four-chamber views were displayed and apical full-volume acquisition was obtained in 126 subjects to visualize the entire left ventricular in a volumetric image. The full-volume images were recorded and then were analyzed by on-line 3DT analysis software. The longitudinal peak systolic strains of left ventricular by using 3DT were compared. Results: ①The LS of apical segment was larger than that of the basal segment and the middle segment, and it had a decreasing trend from the apical segment to the basal segment. But the difference was not statistically significant.②The LS value of the five groups showed a decreasing trend with age, and significant difference was found except for the two segments of anterior septum and apical segment of lateral wall. The global LS value of group A, B and C was larger than that in group D and E. And this difference was statistically significant. Conclusion: The global and 16 segments LS of left ventricular wall has a certain pattern in increasing with age after birth to adolescence with the development of the heart.

LEI Wei;XU Xiu-fang;YU Ri-sheng;CUI Feng;XU Kun-yuan
DOI:
Objective: To evaluate the application of multiple scan modes in 128-slice dual-source CT coronary angiography. Methods: 603 patients of chest pain and chest tightness with heart rate ≤65bpm were examined by CT coronary angiography. 186 patients were examined using the prospective ECG-gated flash spiral(FS) mode; 102 patients were examined using the prospectively ECG-gated sequence(S) mode; 315 patients were examined using the retrospective ECG-gated low-pith spiral(LS) mode, in which 45 cases had arrhythmia. The radiation dose of three modes was used for analysis of variance. The radiation dose was compared between the group of normal cardiac rhythm and the group of arrhythmia. Results: The percentage of diagnosable segments was similar with 99.4% for FS mode, 99.5% for S mode and 99.2% for LS mode, but there was significant difference among three modes in radiation dose with (0.91±0.05) mSv for FS mode and (5.48±0.95) mSv for S mode and (9.19±3.00) mSv for LS mode(P<0.01). There were 270 patients of normal cardiac rhythm and 45 patients of arrhythmia in LS mode scanning, and there was significant difference in radiation dose with (8.45±2.44) mSv for the group of normal cardiac rhythm and (13.62±2.09) mSv for the group of arrhythmia(t=-13.428, P<0.01). Conclusion: The three modes(FS, S and LS) of 128-slice dual-source CT coronary angiography can obtain good image quality, but the radiation dose of FS mode were further significantly lower compared with S mode and LS mode. FS mode is an effective means to achieve low radiation dose for CT coronary angiography. Different scanning modes should be used according to the heart rate and rhythm of the patients to enable scan optimization.

DOI:
Objective: To investigate the quantitative analysis of tissue diffusion by ultrasonic elastography in the grading of fatty liver. Methods: Thirty-six patients’ liver tissue samples were graded according to their level of steatosis. Before liver biopsy, the gray scale ultrasonography was performed in all patients, then, ultrasonic elastography was performed on liver tissue of ROI. The percentage of blue color in the ROI was calculated by the quantitative analysis of tissue diffusion. The elastogram was compared with level of liver steatosis. Results: Steatosis level of the thirty-six patients’ liver tissue: less than 30%(normal group) in 12 patients, 30%~50%(mild fatty liver group) in 9 patients, 50%~75%(moderate fatty liver group) in 8 patients and more than 75%(severe fatty liver group) in 7 patients. There were different characteristics in the groups’ elastogram. The difference of percentage of the blue color in ROI was statistically significant among groups. The correlation coefficient of percentage of the blue color in the ROI area and pathological stage of liver steatosis was r=0.832(P=0.000). Percentage of blue area increased with the degree of fatty liver. Conclusion: The quantitative analysis of tissue diffusion is helpful for the diagnosis in the fatty liver degree, and plays an important role in clinic.

DOI:
Objective: To study the early response of rAd/p53 in nude mice bearing human colon cancer model of SW480 using MR-DWI. Methods: The tumor pieces of human colon cancer SW480 were injected subcutaneously into 52 nude mice. These mice were divided randomly into two groups that is the control group and the therapeutic group. rAd/p53 was injected into the tumor of the mice in the therapeutic group, while saline was injected into the tumor of the mice in the control group. At 24 h, 48 h, 72 h, 120 h and 168 h after treatment, MR-DWI was performed with 1.5T MR system for five mice at each time point of each group. Then the mice were sacrificed and the tumor in which were removed. P53 expression(western blot) and apoptosis of tumor(TUNNEL) were assessed. Results: ADC values of tumors in each time point after rAd/p53 injection were higher than those of the control groups. EADC values after rAd/p53 injection were lower than those of the control groups. p53 expression and apoptosis of the tumor in the therapeutic group were higher than that of the control groups. ADC value showed positive correlations with the extent of apoptosis of tumor cells and showed positive correlation with p53 expression. EADC value showed negative correlations with the apoptotic extent of tumor cells and negative correlation with p53 expression. Conclusions: ADC value and EADC value change significantly at 24 h after treatment. They can be used as biomarker in evaluation of early response of rAd/p53 in the treatment of tumor.

DOI:
Objective: To investigate the therapeutic effect and the expression of proliferating cell nuclear antigen(PCNA) in renal implantation tumor after transcatheter arterial chemoembolization(TACE). Methods: VX2 tumor was inoculated directly into the exposed kidney by tumor blocks embedding in twenty-two New Zealand white rabbits. When the diameter of tumors reached 1~2 cm, the rabbits bearing tumor were randomly divided into two groups, control group(group A n=10) and experimental group(group B n=12). For group A, normal saline was administered via hepatic artery. For group B, lipiodol(0.2 mL/kg) and ADM(2 mg/kg) were administered for each rabbit. Seven days after embolism, the rabbits were sacrificed and the tumors were taken out. All specimens were fixed by 10% neutral formalin, embedded with paraffin completely and consecutive sections were made with a 5 μm-thickness. Then immunohistochemistry was performed to demonstrate the expression of PCNA. Results: PCNA was expressed in 22 animals in two groups(the postive rate=100%). The PI (71.6±11.01)% of residual tumor cells of group B was higher than that of group A (61.2±11.21)%(P<0.05). Conclusions: TACE is a minor trauma and effective treatment for rabbits VX2 renal tumor, the proliferation of residual tumor cells is increased effectually in experimental group.

DOI:
Objective: To investigate pathologic characteristics and the value of imaging findings in diagnosing urachal carcinoma. Methods: The imaging findings in 4 cases examined by CT or MRI with pathologically-proved urachal carcinoma were collected. The image characteristics were retrospectively analyzed and compared with histological features. Results: In the 4 cases of urachal carcinoma, the foci observed in CT or MRI imaging were located at the urachal area in the Retzius space of mid-abdominal line, with 3 cases on the top or anterior wall of the bladder at urachus-bladder junction, 1 case at the upper end of urachus. Among the 4 cases of urachal carcinoma, there was 1 case with solid changes, and 3 cases with cystic changes. All the cases had central or peripheral dotted calcification. All the 4 cases showed different degrees of enhancement. Conclusion: CT or MRI is an effective imaging modality in the localization and qualitative diagnosis of urachal carcinoma. Moreover, it can provide more anatomical information for surgery.
