Magnetic resonance evaluation of double uteri

A total of 18 infertile patients with hysterosalpingographic diagnosis of bifid uterus underwent magnetic resonance imaging (MRI) and subsequent laparoscopy or laparotomy to evaluate the capability of MRI to differentiate among the various classes of the malformation. Magnetic resonance imaging identified both bicornuate uteri correctly, both didelphic uteri, nine of the 12 partial septate uteri, and both complete septate uteri. The method demonstrated a sensitivity of 100% and a specificity of 78.6% in demonstrating cervical prolongation of the spur. Compared with laparoscopy, MRI is less expensive and less invasive, and can also be performed in patients with extensive adhesions. However, it has the disadvantage of not providing information on tubal conditions or on the presence of minimal and mild endometriosis.
