Prenatal diagnosis of fetal urogenital abnormalities with oligohydramnios by magnetic resonance imaging using turbo spin echo technique.
Turbo spin echo technique is a sequence that enables T2 weighted magnetic resonance (MR) images to be obtained in a few seconds. The purpose of this study is to evaluate the usefulness of this sequence in the prenatal diagnosis of fetal urogenital abnormalities associated with oligohydramnios, which make the ultrasound examination inconclusive. Two fetuses suspected of having prune belly syndrome and polycystic kidney on ultrasound examination were studied by MR imaging using turbo-spin echo method in utero. The images were compared with prenatal ultrasonography or post-mortem findings. In both fetuses, abnormalities were diagnosed correctly. This sequence is useful because it provides images of diagnostic quality in a very short scanning time.
