PURPOSE: To determine the value of diffusion-weighted MRI for the diagnosis of acute appendicitis in children.
MATERIALS AND METHODS: Forty-five consecutive patients with a clinical diagnosis of acute appendicitis underwent abdominal MRI; 39 were operated on for acute appendicitis. First, the diffusion-weighted imaging (DWI) alone was reviewed, followed by conventional MRI alone, and then conventional MRI and DWI were reviewed by two observers within a consensus. The surgical findings were compared with the MRI. Sensitivity, specificity, and accuracy were calculated for DWI, conventional MRI, and combined DWI and conventional MRI for the depiction of acute appendicitis.
RESULTS: A combination of DWI and conventional MRI was the most sensitive and the most accurate, with corresponding sensitivity and accuracy of 0.92 and 0.92, respectively. Using DWI alone the sensitivity and accuracy was found to be 0.78 and 0.77, respectively. Using conventional MRI alone, sensitivity of 0.81 and accuracy of 0.82 was found for the consensus of the two observers.
CONCLUSION: The use of combination of DWI and conventional MRI is a valuable technique in the diagnosis of acute appendicitis in children.
