Abstract
Three dimension ultrasound (3D US) is the standard and primary modality used for the imaging of the fetus. It is widely available, easy to apply, cost‐effective, safe for the fetus and allows real‐time imaging. However, it has some limitations. Especially in case of oligohydramnios, large maternal body habitus and inappropriate fetal position, its effectiveness reduces. Also in the evaluation of some body parts and complex pathologies , the results of 3D US might be unclear. In such cases, MR imaging is being increasingly used as a complementary imaging Magnetic resonance imaging is an alternative modality that uses no
ionizing radiation, has excellent tissue contrast and a large field of view, is not limited by obesity or overlying bone, and can image the fetus in multiple planes, no matter the fetal lie. Faster scanning techniques allow
studies to be performed without sedation in the second and third trimester with minimal motion artifact. To date, it has not been shown that MR
imaging has any adverse effects on the fetal growth or development but,may be some limitations in imaging of cases with severe oligohydramnios. The aim of our study is to compare the precision and accuracy of 3D ultrasonography and MR imaging in diagnosis of fetal malformations and correlate their results with the postnatal findings.This prospective study was carried out on 40 patients attending
Radiology and Medical imaging department of Tanta University Hospital which have been suspected by 2D ultrasound as having fetal malformations. Then 3D ultrasonography and MRI studies were performed after taking full detailed history and a written consent from each patient then, the diagnosis by both modalities were correlated with postnatal findings.
