[An MRI study of the normal pelvis in the immediate postpartum period].

Purpose: To describe the MR findings of the pelvis in the early post-partum period, after vaginal delivery or cesarean section.
Materials and Methods: Fifteen asymptomatic patients were imaged using a 1.5 Tesla MR unit between 1 and 7 days following delivery. Eight patients had a vaginal delivery, and seven patients had a cesarean section.
Results: The following items were evaluated: uterus size, architecture, and contents; uterine and abdominal wall scars; parametrium; peritoneal cavity; ovarian veins.
Conclusion: MRI provided a good evaluation of the pelvic changes related to pregnancy and delivery. Knowledge of the normal findings should improve diagnosis of early post-partum complications.
