[Magnetic resonance imaging of the pelvis]

Magnetic resonance imaging (MRI) is particularly well suited to pelvic explorations. Normal uterine zonal anatomy and its variations within the menstrual cycle are well codified. MRI is the best preoperative imaging modality for the localization of fibroids. MRI allows a good approach to tissue characterization in benign ovarian tumors and a precise loco-regional assessment in malignant tumors. It could eventually replace the surgical second look after therapy. In prostate cancer, MRI is the most accurate imaging modality to assess capsular invasion.
