MR evaluation of uterine anomalies.

The MR features of uterine anomalies were analyzed in eight women. Scans were done on a 1.5-T magnet with T1-weighted (TR 600 msec, TE 25 msec) and T2-weighted (TR 2000-2500 msec, TE 35-80 msec) spin-echo images obtained in several planes. The anomalies consisted of bicornuate uterus (three cases), septate uterus (one case), bicornuate uterus with septation (two cases), unicornuate uterus (one case), and uterus didelphys with vaginal septum (one case). These diagnoses were confirmed by hysterosalpingography with laparoscopy (five cases), dilation and curettage with laparoscopy (one case), or cesarean section (two cases). In six of the eight cases, MR correctly identified and accurately classified the type of anomaly. In the other two cases, the MR diagnosis was a bicornuate uterus with septation. One case proved to be a uterus didelphys with vaginal septum, and the other a bicornuate uterus without septation. The study shows that MR is a valuable tool for the diagnosis of uterine anomalies.
