MRI and fluoroscopic defecography are diagnostic tests used to identify abnormalities that cause pelvic floor disorders. These tests can advise doctors to improve the diagnosis and provide the appropriate treatment plans.
What is an MRI?
Magnetic resonance imaging (MRI) is a non-invasive diagnostic imaging modality that uses magnetic fields and radiofrequency pulses to produce detailed images of the body's internal structures. It provides highly detailed and accurate images of the soft tissues, including the pelvic floor muscles and structures. The MRI machine produces a strong magnetic field to align hydrogen atoms within the body, which emits signals that are detected by computer software to create images.
What is fluoroscopic defecography?
Defecography is an imaging test that assesses the rectum and its surrounding pelvic floor muscles. Fluoroscopic defecography uses X-rays to create a video of the rectum and colon while a person has a bowel movement. During the test, a special dye is inserted into the rectum through a small tube. This dye helps to visualize the anatomic structures and helps to identify pelvic floor abnormalities during defecation.
