Abstract：
:A brief description of normal MR anatomy is presented, followed by a discussion of the main indications for MR imaging of the pelvis in children. The evaluation of congenital anomalies of the genital tract in boys and girls, including ectopic testes, abnormalities of the uterus and vagina, and of the anorectal region, are reviewed. A discussion of the role of MR imaging in evaluating the internal characteristics and extent of benign and malignant pelvic masses is included. The main indications for MR of the pelvis in children are discussed, after a brief description of normal anatomy.
