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 magne tic 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 p renatal diagnosis of fetal urogenital abnormalities associated with ol igohydramnios, which make the ultrasound examination inconclusive. Two fetuses suspected of having prune belly syn drome and polycystic kidn ey on ultrasound examination were studied by MR imaging using turbo-sp in echo method in utero. The images were compared with prenatal ultras onography or post-mortem findings. Ln both fetuses, abnormalities were diagnosed correctly This sequence is useful because it provides image s of diagnostic quality in a very short scanning time.
