Bony avulsions about the knee are common injuries seen in the emergency room. Unawareness of characteristic radiographic patterns of injury that herald potential instability and require further workup can result in significant morbidity. We present a radiographic pictoral discussion on bony avulsions and associated soft tissue complex injuries on MRI. ...

Blunt abdominal trauma is a leading cause of trauma related mortality. Currently, the gold standard in the radiographic evaluation of intra-abdominal injury is computed tomography (CT) with iodinated contrast material. However, in the setting of renal failure or a previous anaphylactic reaction to contrast material, radiographic evaluation of the trauma ...
