MRI of the fistulography

Starting from


MR fistulography is a diagnostic technique used to visualize fistulas in the body using magnetic resonance imaging (MRI). This technique enables the depiction of abnormal passages or connections between two cavities or between cavities and the body surface. MR fistulography is often used for diagnosing and evaluating various types of fistulas, including anal fistulas, intestinal fistulas, or other types of abnormal openings. This technique provides detailed images of fistulas, aiding physicians in establishing an accurate diagnosis and planning appropriate treatment.



You need MR fistulography during surgical/proctological treatment of acute or chronic pain in the perineal region, the area around the groin, as well as evident acute or chronic inflammatory processes with leakage of purulent content around the groin. Some of these conditions carry a high risk for the patient's health, the possible development of extensive inflammatory changes with sepsis and other inflammatory conditions of the retroperitoneal soft tissues that can threaten the patient's life and should be diagnosed in time in order to carry out successful treatment.


The day before the examination, it is necessary to take a cleansing agent in order to empty the intestines well, which allows for an unobstructed view of all the structures of the small pelvis and perineum. Come to the examination on an empty stomach.


The search is pleasant and painless. Intravenous contrast agents are not administered during the examination. During the examination, the soft tissues of the perineal region, the area around the terminal colon and rectum, and the structures of the small pelvis are analyzed.
