Detection and mapping of intraabdominal adhesions by using functional cine MR imaging: Preliminary results

PURPOSE: To identify and map intraabdominal adhesions by using functional cine magnetic resonance (MR) Imaging. MATERIALS AND METHODS: Twenty-seven patients suspected of having intraabdominal adhesions were examined. Section-by-section dynamic:depiction of induced visceral slide throughout the whole abdomen was achieved by using a transverse or sagittal true fast imaging with steady-state precession sequence. Location and type of diagnosed adhesions were documented by using the nine segments of the abdominal A map. These criteria and intraoperative results were compared in 13 patients. RESULTS: MR images depicted a total of 42 intraabdominal adhesions; 21 (50%) were in the lower abdomen. The most common types of adhesions were located between the ventral abdominal walt and smalt-bowel loops (n = 10 [24%]) and between adjacent small-bowel loops (n = 9 [21%]). Comparison with the intraoperative results showed a sensitivity of 87.5% and a specificity of 92.5%. MR imaging was most accurate in depicting adhesions to the abdominal wall (15 [94%] of 16) and subperitoneal space (eight [100%] of eight). The presence of adhesions between tween bowel loops was overestimated. CONCLUSION: Detection of Visceral slide at functional cine MR imaging is easy to perform and represents a well-tolerated and accurate procedure for use in the identification of intraabdominal adhesions in patients with chronic pain and equivocal clinical findings.
