摘要

Objective: We aimed to evaluate the contribution of diffusion-weighted magnetic resonance imaging (DW-MRI) to computed tomography (CT) in patients with acute abdominal pain admitted to the emergency department. Material and Method: Between August 2014 and November 2015, a total of 2365 patients with acute abdominal pain were admitted to the emer- gency department. 1680 of those underwent CT imaging. In 720 patients (mean age, 50.17; range, 16-89 years: 379 females, 341 males) DW-MRI was performed before CT scans. 960 patients who had no diffusion imaging were excluded from this study. Pregnant women, children under the age of 16 years old, most of urinary stones and all of bowel obstructions were also excluded from this study. The strategy of imaging review was as fol- lows: 1-evaluation of DW-MRI alone, 2-evaluation of CT alone, and 3-evaluation of both modalities (DW-MRI and CT images). Images were evalua- ted by different radiologists with at least 5 years of experience in abdominal imaging interpretation, blind to the final diagnosis. Every reader was aware of the clinical symptoms and laboratory results of patients. Results: The sensitivity and accuracy of combined imaging (DW-MRI and CT) was higher than CT alone for the detection of cause in acute abdomi- nal pain. This was dramatically higher in non-enhanced CT (NECT) rather than contrast-enhanced CT (CECT) scanning. Conclusion: DW-MRI is a noninvasive technique that may be used to improve the accuracy of CT in many cause of acute abdominal pain, especially in patients undergoing non- enhanced CT scans.
