ZHOU Wen-hui;WANG Qin;HU Jiu-yi;XIE Xiao-ping
DOI:
Objective: To study MRI features of cerebral venous malformation(CVM) and assess the value of each imaging sequence. Methods: MRI and three-dimensional multiple overlapped thin slab acquisition(3D-MOTSA) MR angiography(MRA) were performed in 8 cases with CVM. Six patients were imaged by MR scanner with Gd-DTPA enhanced T1WI, and 3 of them underwent additional 3D-MOTSA CE MRA. Results: In 4 cases the lesions were located in cerebellum and 4 cases in frontal lobe, parietal lobe or occipital lobe. In 5 cases, MRI showed draining veins which were hypointense on T1WI and T2WI, hypointense on T1WI and in 3 cases showed hyperintense on T2WI, while medullary veins showed hypointense on T1WI and hyperintense on T2WI. After enhancement, numerous radiating medullary veins gathered together into one or two larger draining veins and flowed into superficial or deeper veins, demonstrating the so-called “Caput Medussa” appearance. 3D-MOTSA MRA showed some draining veins, but a few medullary veins. 3D-MOTSA CE MRA could show the whole length of the draining veins in 3 cases, the number of medullary veins were numerous. Conclusion: MRI could diagnose the complications of CVM accurately and make up for the deficiency of cerebral angiography. 3D-MOTSA CE MRA could replace cerebral angiography.

FEI Hong-wen;WANG Xin-fang;XIE Ming-xing;HE Ya-le
DOI:
Objective: Transmitral flow velocity to mitral annular velocity ratio(E/E’) had a strong positive relationship with left ventricular filling pressure, which presents as a good indicator for evaluating left ventricular diastolic relaxation abnormality. The present study was designed to evaluate myocardial relaxation function changes in an Adriamycin-induced cardiomyopathy model using E/E’. Methods: Twenty-eight Japanese rabbits were divided into two groups. Adriamycin was administered intravenously at a dose of 2mg/kg once a week for 8 weeks(total dose 16mg/kg) in 20 rabbits to induce the cardiomyopathy model. Eight rabbits served as controls receiving the same amount of saline once a week for a total of 8 weeks. Conventional and tissue Doppler echocardiography were performed at baseline, 4th week, 6th week, 8th week, 10th week, 12th week. Results: In the Adriamycin-treated group, LV chamber diameter significantly increased, while ejection fraction and fraction shortening decreased significantly in the 10th and 12th week(P<0.05). The significant changes were first found in the 10th week. Mitral annulus systolic peak velocity by TDE decreased significantly in the 8th, 10th and 12th week(P<0.05). The significant changes were first found in the 8th week. The ratio of E/E’ significantly increased in the 6th, 8th, 10th and 12th week(P<0.05). The significant changes were first found in the 6th week. In the control group, no significant changes were found in all parameters by tissue Doppler, conventional echocardiography(P>0.05). Conclusions: Myocardial function was reduced in Adriamycin-induced rabbit model of dilated cardiomyopathy. The relaxation parameter(E/E’) by TDE changed earlier than contraction indices by TDE and conventional echocardiography in Adriamycin-induced cardiomyopathy rabbits, which provide a new sensitive and reliable method to evaluate LV relaxation function.

HU Hai-jing;HUANG Biao;LI Chun-fang;LI Liang;ZHANG Ying-he
DOI:
Objective: To evaluate MRI features in cervical lymphadenopathy. Methods: Sixty-eight patients with cervical lymphadenopathy underwent both plain and enhanced MRI. Fat-suppression imaging was routinely performed using the chemical shift imaging(CSI) and fat saturation(FS) technique. Morphological features and signal intensity characteristics of MRI were analyzed and compared with pathological results. Results: Diagnosis was verified by pathology. Twenty cases had cervical tuberculous lymphadenitis, 33 had malignant lymph node metastasis and 11 had malignant lymphoma. MRI detected round lymph nodes (with the long axis/short axis<2) in 45 cases(8 with tuberculosis, 28 with malignant metastasis and 9 with lymphoma), and oval lymph nodes(with the long axis/short axis>2) in 19 cases(12 with tuberculosis, 5 with malignant metastasis and 2 with lymphoma). Thirty-five cases manifested with necrotic focus locating in the centre of the lymph node revealed in T1WI and T2WI and thin-walled rim enhancement revealed in T1WI(6 with tuberculosis, 27 with malignant metastasis and 9 with lymphomas). Ill defined margin of the lymph node and invasion of adjacent adipose tissue were found in 35 cases(5 with tuberculosis, 28 with malignant metastasis and 2 with lymphoma). Nine cases with lymphoma showed homogeneous signal intensity on MRI. Conclusion: MRI is significant in the evaluation of enlarged cervical lymph nodes. It is an important examination in the diagnosis and differential diagnosis of cervical lymphoadenopathy.

DOI:
Objective: To investigate the correlation between characteristic features of spiral computed tomography(SCT) and the expression of vascular endothelial growth factor(VEGF) and microvessel density(MVD) in intrahepatic cholangiocarcinoma(IHCC). Methods: Triple-phase SCT scanning was performed in 24 patients with 28 pathological confirmed IHCC lesions. SCT signs were observed. Immunohistochemical analysis was carried out in 28 lesions to examine the expression of VEGF and quantity MVD by using antibodies against CD34 in IHCC. The features of SCT were compared with all immunohistochemical results of IHCC. Results: Size of the lesions, invasion and metastasis of IHCC on CT scanning correlated with the expression of VEGF(P<0.05); tumor edge, size of the lesions, invasion and metastatic bile duct dilation and delayed enhancement pattern of IHCC correlated with MVD(P<0.05). Conclusion: SCT imaging features could reflect tumor angiogenesis in certain extent and infer the expression of VEGF, which is very helpful for its early diagnosis and the selection of proper therapy.

DOI:
Objective: To probe the imaging characteristics of aortic left ventricular tunnel(ALVT) in color Doppler echocardiography(CDE). Methods: Seven patients with ALVT were examined by CDE, to find out the character of ALVT. All of the 7 patients underwent angiocardiography for correlation. Of them, 5 cases were confirmed by operation. Results: Five cases were accurately diagnosed by imaging character of CDE, 1 case was misdiagnosed as the left coronary artery left ventricular fistula, the other one was misdiagnosed as the aortic valve stenosis with insufficiency. The features of CDE image were obvious as follows: ①The parasternal long axis view of two-dimensional echocardiography(2DE) image on the front or back wall of aortic valve showed non-echo tubal cavity was connected with left ventricular outflow-tract. CDFI showed that blood flow sign entered into the non-echo cavity from left ventricular outflow-tract during systolic time, and vice versa during diastolic time. ②The parasternal short axis view of 2DE image showed semilunar echoless cavity between aortic sinus and aortic wall. CDFI showed blood flow signal in echoless cavity. ③Most patients associated with aortic valve hypoplasia and aortic valve insufficiency, half with mitral insufficiency and very few with ventricular septal defect. Conclusion: The feature of CDE image in ALVT was obvious. CDE was valuable especially in diagnosing ALVT, but it should be differented from coronary artery fistulas, aortic dissecting aneurysm and aortic valve insufficiency.

ZENG Hui-ru;ZHAO Jin-hui;LIU Tong;LI Ling
DOI:
Objective: To investigate whether the spontaneous closure of ductus arteriosus could be predicted by early echocardiographic indices. Methods: The term neonates were examined with echocardiography 1 to 3 days after birth. The presence or absence of a hemodynamically significant ductus shunt was judged from echocardiographic indices. If the ductus arteriosus was not closed, follow-up research were made. From January 1995 to March 2005, there were 45 subjects in our hospital whose ductus did not close spontaneously within a one-year follow-up(PDA group), and 50 subjects whose ductus closed spontaneously within 3 days were collected randomly served as controls(CONTROL group). The echocardiographic indices were compared between the two groups. Results: The LA/AO, LVIDd/AO, the smallest width of ductal color Doppler flow jet and the velocity at the pulmonary end of the duct in PDA group were found to be significantly higher than those in CONTROL group(P<0.001, P<0.01, P<0.001, P<0.001 respectively). LA/AO<1.30, LVIDd/AO<1.82, and the smallest width of ductal color Doppler flow jet<0.29cm were good indicators for prediction that the ductus arteriosus could be closed spontaneously. LA/AO>1.39, LVIDd/AO>1.97, and the smallest width of ductal color Doppler flow jet>0.33cm indicated that the ductus arteriosus could not be closed spontaneously, and further treatment was necessary. Conclusion: The early echocardiographic indices of term neonates was very valuable to predict the spontaneous closure of ductus arteriosus.
