Review the value of MRI in diagnosing appendicitis in pregnant and non-pregnant women. Discuss MRI techniques/protocols, tips and tricks for visualization of the appendix in pregnant and non-pregnant women. Use a case-based approach to illustrate the MRI techniques to evaluate appendicitis in a spectrum of pregnant and non-pregnant women, including some examples of alternative diagnosis.

1)  Anatomy of the appendix. Pathophysiology of appendicitis. Value of each imaging modality (U/S, CT, MR). MRI indication/significance in pregnant and non-pregnant women. 2) Advantages & limitations of using MRI, and MRI interpretation of the appendix. 3) MRI protocol/techniques for visualizing appendix in pregnant women (time of acquisition, best sequence to visualize the appendix, cecal tilt angle, diffusion-weighted imaging.) 4) MRI utility in ruling in/out other medical conditions associated with acute RLQ abdominal pain (ectopic pregnancy, ovarian torsion, IBD, degenerating fibroids).
