Abstract
Magnetic resonance imaging (MRI), although not usually the first diagnostic study in assessment of acute abdominal pain, can offer a radiation-free high tissue-contrast resolution alternative to CT. MRI can be particularly useful in assessment of young or pregnant patients, or patients with renal insufficiency precluding administration of intravenous contrast. In this article, we review MRI appearance of a number of acute abdominal and pelvic processes, including hemorrhage and various ischemic, inflammatory, and infectious conditions.
