Aim The aim of this review was to evaluate the efficacy of magnetic resonance imaging (MRI) in determining appendicitis during pregnancy. Methods We retrospectively reviewed the clinical course for all pregnant patients with suspected appendicitis from 2013-2018. We evaluated the efficacy of MRI and Alvarado scoring and its impact on management. Results Twenty-nine pregnant patients with suspected appendicitis had an MRI. The majority (90%, n=26/29) had normal diagnostics with two patients (10.3%) having findings consistent with acute appendicitis. Two other patients proceeded to laparoscopy, one with an inconclusive MRI, and one patient with clinical appendicitis. We found no accurate correlation between pregnancy and Alvarado scoring. Conclusion MRI is a safe adjunct in accurately diagnosing appendicitis in pregnancy. Its routine use could help reduce rates of negative appendectomies and the potential risk to maternal and fetal health.
