A case report of MR imaging of traumatic hemobilia.

The diagnosis of hemobilia is difficult. Computed tomography and ultrasonography generally yield only contributory information about blood or clots in the gallbladder but cannot demonstrate bleeding. This case report shows that magnetic resonance imaging (MRI) can not only demonstrate traumatic hemobilia in the gallbladder, and its origin, but can also determine active bleeding from liver lacerations and hematoma.
