Objective To evaluate the clinical diagnostic value and limitation of MRI and contrast enhancement MRA (CE-MRA) in congenital heart disease of children. Methods Three hundred patients with congenital heart disease underwent CE-MRA. 173 were confirmed by operation. The results of MRA and CE-MRA were compared with operation data. Results 196 (86.0%) intracardiac malformation including septal defect and valve anomaly were diagnosed correctly by MRI within 228 abnormalities which were confirmed by operation. 101 (96.2%) extracardiac malformation including great vessels stenosis and anomalous connection were diagnosed correctly by MRI and MRA within 105 abnormalities which were confirmed by operation. Conclusion MRI and CE-MRA are very accurate diagnostic method for extracardiac malformation. CE-MRA is the best sequence for congenital heart disease.

Objective To report 6 cases of congenital heart disease with high origin of coronary artery and to evaluate the imaging method for diagnosis of congenital high origin of coronary artery. Methods Six patients with congenital high origin of coronary artery underwent angiocardiography ,echocardiography ,and 2 patients also underwent magnetic resonance examination. All 6 cases were confirmed by operation. Results All 6 cases were congenital high origin of right coronary artery. Angiocardiography made correct diagnosis in all 6 cases; MRI made the correct diagnosis in 1 of the 2 cases; echocardiography made 1 correct diagnosis. Conclusion Correct diagnosis of congenital high origin of coronary artery was very important for patients with congenital heart disease. Angiocardiography was a very reliable imaging method and MRI can play an important role in preoperative diagnosis of congenital high origin of coronary artery.

Objective To evaluate different angiocardiographic techniques of congenital heart disease in children. Methods 11045 pediatric patients with congenital heart disease were performed angiocardiography using cut film, cine film and digital subtraction angiography(DSA) equipments. Different angiocardiographic techniques were used. Results The diagnostic accuracy of cut film with conventional AP and lateral views was 80.5%,the diagnostic accuracy of cine film with angulated views was 90.0% and the diagnostic accuracy of DSA using non-ionic contrast medium with angulated views was 96.5%. Conclusion Dynamic picture angiography with digital subtraction using non-ionic contrast medium under rapid injection is the key for claiming the high quality imaging diaguosis of congenital heart disease in children.

Objective To explore the diagnostic value of MRI on fetal neural tube defects.Methods Ten pregnant women,aged from 25 to 35 years(average 28 years)and with gestation from 20-39 weeks(average 33 weeks)were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound(US)studies.The imaging protocol included fast-imaging employing steady-state acquisition,single-shot FSE and T_1-weighted fast inversion recovery motion insensitive sequences in the axial,frontal,and sagittal planes relative to the fetal brain,thorax,abdomen,and spines.Prenatal US and MRI findings were compared with postnatal MRI diagnoses(3 fetuses)or autopsy(7 fetuses).Results Ten pregnant women(9 with a single fetus and 1 with twin fetuses)were examined.For all cases,the diagnoses established by MRI were correct when compared with postnatal diagnosis or autopsy.In 7 cases,US and MRI findings were in complete agreement with postnatal diagnoses.US missed the diagnosis in 1 case and misdiagnosed in 2 cases.Ten neural tube defects in this study included anencephaly(1 case),exencephaly (1 case),meningoencephalocele associated with amniotic band sequence(1 case),meningocele(1 case),thoracic myelomeningocele(1 case),lumbar spinal bifida(1 case),sacroiliac myelomeningocele(2 cases),sacroiliac large cystic spinal meningocele(1 case),sacroiliac spinal bifida(1 case).Conclusions Prenatal MRI is effective in the assessment of fetal neural tube defects.It can exactly discriminate herniated contents and locate the spinal lesion level.

Objective To explore the diagnostic value of MRI on fetal congenital diaphragmatic hernia(CDH).Methods Fourteen pregnant women with gestation from 16 to 39 weeks were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound studies.Fast-imaging employing steady-state acquisition(FIESTA),single-shot fast spin echo(SSFSE)and T_1-weighted fast inversion recovery motion insensitive(FIRM)sequences were employed on the axial,coronal and sagittal planes of the fetal brain,thorax and abdomen,especially the thorax.Prenatal US and MR imaging findings were compared with postnatal diagnoses(13 fetuses)or autopsy(1 fetus).US,MR imaging and surgery were used for postnatal evaluation.Results Fourteen pregnant women(12 with a single fetus and 2 with twin fetuses)were studied.There were 12 fetuses(in 2 cases,being one of twins)with a left-sided and 2 with right-sided diaphragmatic hernias.For all cases,the prenatal MRI diagnosis Was correct when compared with postnatal diagnosis or autopsy.Two CDHs were missed and 2 were misdiagnosed by US.Intrathoracic herniated organs in 12 left CDH included the colon(n=1),the stomach(n=1),the bewel(n=5),or both the stomach and bowel(n=5).Intrathoracic herniated organs in 2 right CDH included the bowel(n=1),or the bowel and the right lobe of the liver(n=1).Conclusion Prenatal MRI is effective in the assessment of fetal congenital diaphragmatic hernia.

Objective To explore the diagnostic value of MRI on fetal congenital limb deformities.Methods Sixteen pregnant women,aged from 22 to 40 years (average 29 years) and with gestation from 22 to 39 weeks (average 29 weeks) were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound studies. Acquisitions consisted of coronal, sagittal, and axial slices relative to the fetal brain, spine, thorax, abdomen, especially limbs using 2D FIESTA sequences. Prenatal US and MR imaging findings were compared with postnatal diagnoses (4 fetuses) or autopsy (12 pregnant women,13 fetuses). Postnatal evaluation included US, MR imaging, computed tomography, and physical examination. Results Of the sixteen pregnant women (15 with a single fetus and 1 with twin fetuses) ,17 fetuses were found. Those limb deformities of sixteen pregnant women included congenital both upper extremities amelia (1 case), sirenomelia sequence (1 case), micmmelia (5 cases, 1 of which were twins),bilateral clenched hands (2 cases), right pelydactyly (1 case), simple right ectrodactyly (1 case), right dactylolysis(1 case), simple club foot (2 cases), hydrocele spinalis with club foot (2 cases), 1 of the 2 cases with bilateral clinodactyly. In 14 of 16 cases, the diagnoses established by MR imaging were correct when compared with postnatal diagnosis, and prenatal MR diagnosis was inaccurate in 2 cases. Conclusion Prenatal MRI is effective in the assessment of congenital limb deformities of fetuses, it can yield information additional to that obtained with US, and further correct US diagnosis.

Objective To find an ideal liver cirrhosis portal hypertension model in big animals suitable for surgical study.Methods Twenty canines were treated by subcutaneous injection of 60% CCl4 colza oil emulsion into the back,at a dose of 1.0-1.3 mL/kg every 10 days for a total of 6-8 times.At the same time,it was combined with the control of food intake.All canines were fed with rice mixed with 10% hog fat.The amount of rice was 15 g/kg per day from the first day to the forth day,but the amount of food was not controlled from the fifth day to the tenth day.During the process,the canines′ general condition was observed and the changes of hepatic functions such as ALT,TP,ALB,G and A/G were measured.The changes of liver morphology,the diameter and blood flow of portal vein were monitored with color Doppler.Every two weeks,a piece of hepatic tissue to observe the pathological change of liver was excised operatively.Results During the process,the body weight of the canines decreased continually;ALT increased during early and middle stages and decreased during advanced stage;TP and ALB always decreased,and A/G continuously decreased,but G did not change significamtly.Eight weeks after injection,liver became progressively smaller.its density was not well-distributed,and liver particles gradually became coarse,and liver capsule became rough.The diameter of portal veins became larger and the velocity of portal vein became slower.Liver cirrhosis with psudolobules was found on light microscopy from the tenth week to the twelfth week.Three canines died,with mortality of 15.0%.Conclusions It took 10-12 weeks to establish this liver cirrhosis portal hypertension models in canines by subcutaneous injection of CCl4.This method is convenient,has high success rate,and is suitable for use in surgieal research.
