To provide a simple overview of the anatomy of the pelvic floor. To explain the MRI technique and criteria for diagnosing pelvic floor dysfunction. To show the MRI findings for pelvic floor dysfunction.
About 50% of all women aged > 50 years suffer from pelvic floor dysfunction; nearly 11% of those who seek medical help have already undergone surgery,
and 30% of these require repeat surgery. Pelvic floor dysfunction can involve multiple structures and can manifest with different symptoms such as urinary or fecal incontinence,

Findings and procedure details
Anatomy: - Compartments The pelvic region is divided into three compartments: Anterior compartment: contains the bladder and the urethra. Middle compartment: contains the uterus,
as well as the structures in the rectovaginal fascia. Posterior compartment: contains the rectum and anus. - Anatomical structures The pelvic floor is composed of three horizontal layers,
in craniocaudal order: The endopelvic fascia consists of multiple ligaments or peritoneal reflections that...
Functional MRI is becoming the technique of choice for the evaluation of pelvic floor dysfunction. Without the need for ionizing radiation,
the multiplanar capacity of dynamic MRI and the internal contrast of the pelvic organs provide thorough information about pelvic floor disease that can have a significant impact on surgical treatment.
