In women with lower urinary tract symptoms, a medical imaging technique called dynamic MRI allows clinicians to diagnose pelvic organ prolapse - a condition that often goes undiagnosed on static MRI and at physical examination, according to a study published in the December issue of the American Journal of Roentgenology. Pelvic organ prolapse is relatively common and occurs when the pelvic floor muscles become weak or damaged and can no longer support the pelvic organs.
