Abstract: Objective To investigate the application value of MRI in clinical diagnosis and treatment of anorectal malformation. Method 57 cases with operatively anorectal malformation from February 2008 to August 2011 were collected. All the patients received MRI examination before the operation. Results Of the 57 cases, 23 cases had high imperforate anus with rectum blind end above PC line and the average distance from the nest to the anus was about 3.2cm, 3 cases combined with spinal cord(2 cases with Currarino syndrome), 2 cases with sacrococcyx malformation. There were 2 cases with renal pelvis, 1 case with renal malformation, 1 case with rectovaginal fistula,and 1 case with double uterine malformation. 16 cases had median imperforate anus with rectum blind end near PC line. The average distance from the nest to the anus was about 1.5cm. There was 1 case combined with tethered spinal cord, 2 cases with sacral agenesis and 1 case with hydronephrosis. 18 cases had low imperforate anus with the rectum blind end below PC line. The average distance from the nest to the anus was about 0.8cm. There was 1 case combined with tethered spinal cord, 6 cases with rectal perineal fistula, 1 case with sacrococcyx malformation ,2 cases with hydronephrosis. Incidence rate of postoperative complications in high imperforate anus was higher than the low imperforate anus. Conclusions MRI can display the anorectal malformation type, the presence and walk of fistula, development of spinal cord and lumbarsacral vertebra, and other abnormal conditions accurately and comprehensively. It can offer reliable basis for the choice of operation and anesthesia mode, prediction of complications and evaluation of postoperative prognosis.
