Magnetic resonance imaging in traumatic diaphragmatic rupture: case reports.

Acute traumatic diaphragmatic rupture is usually diagnosed by plain chest x-ray studies or at laparotomy. On occasion, ancillary diagnostic procedures such as computed tomography (CT) and fluoroscopy are necessary for diagnosis. Suspected acute traumatic diaphragmatic rupture was definitively diagnosed by magnetic resonance (MR) imaging in two patients. In another three patients, MR imaging was used to rule out diaphragmatic rupture. Magnetic resonance imaging may be the ancillary diagnostic procedure of choice following equivocal chest radiographs.
