Magnetic Resonance Imaging of the Female Pelvic Floor: Anatomy Overview, Indications, and Imaging Protocols.

This article reviews different approaches for describing pelvic floor anatomy; "Classic 3-Compartment Approach", "Active and Passive Conceptual Approach" and "Multilayered System Approach". However, these approaches cannot explain pathogenesis of various dysfunctions. "Functional 3-Part Pelvic Supporting Systems Approach" a new, more function-based classification of the pelvic floor support system is introduced in which all structures that contribute to same function are grouped under 1 system. Indications for MR imaging of pelvic floor dysfunction, patients' preparation, static, dynamic and MR Defecography imaging protocols are detailed according to the concordance of experts in two recently published consensus papers.
