Core Tip
Core Tip: This study compared diagnostic efficacy of multislice spiral computed tomography, 1.5T magnetic resonance imaging (MRI), and 3.0T MRI for anal fistula in 119 patients. With surgery as gold standard, 3.0T MRI showed significantly higher detection rates, accuracy, sensitivity, specificity, and consistency with surgery for internal openings/main tracts than multislice spiral computed tomography and 1.5T MRI, proving its superior diagnostic value.
