Abstract：Objective To compare the accuracy of magnetic resonance imaging (MRI) imaging with that of computed tomography (CT)
for the diagnosis of acute appendicitis. Methods The subjects were 66 patients with acute abdominal pain in emergency department
of our hospital from March 2017 to October 2018. All patients were examined with enhanced CT and MRI. Three radiologists
reviewed the images to assess the possibility of diagnosing appendicitis with MRI and CT (1-5 score). Results When the possibility
score was no less than 3, the sensitivity and specificity of MRI were 96.9% (95%CI: 88.2%-99.5%) and 81.3% (95%CI:
73.5%-87.3%) respectively; the sensitivity and specificity of CT were 98.4% (95%CI: 90.5%-99.9%) and 89.6% (95%CI:
82.8%-94.0%). When the possibility score was greater than or equal to 4, there was no statistical difference between MRI and CT
(P>0.05). ROC curve analysis showed that the diagnostic accuracy was higher when the probability score was greater than or equal to 4,
and there was no statistical difference between MR and CT imaging in diagnostic accuracy. Conclusion The diagnostic accuracy of
MR imaging is similar to that of CT for the diagnosis of acute appendicitis.
