MRI remains highly accurate in the diagnosis of appendicitis in pregnancy when read by radiologists of mixed specialty training and experience.

MRI is a highly accurate imaging modality for the assessment of appendicitis in pregnancy. Even with variable reader MRI experience, MRI demonstrates an accuracy of 99.8% and a positive predictive value for acute appendicitis of 100%. Double reading and the possible inclusion of DWI may help further improve accuracy and minimise false-negative rates.
