Transient lateral patellar dislocation is frequently difficult to diagnose accurately on the basis of clinical findings. Accordingly, we studied the MR findings in 26 cases to determine if MR imaging is useful in establishing the diagnosis. ⋯ Our findings suggest that patients with transient lateral patellar subluxation have a distinctive constellation of MR findings that can be used to distinguish this entity from other common knee injuries.

Value of contrast-enhanced CT in detecting active hemorrhage in patients with blunt abdominal or pelvic trauma.
The purpose of this retrospective study was to evaluate the use of contrast-enhanced CT to show sites of active hemorrhage as a guide for surgical or angiographic treatment in patients sustaining blunt abdominal or pelvic trauma. ⋯ Active extravasation of contrast material (representing bleeding) can be detected in trauma patients who are physiologically stable enough to undergo CT of the abdomen or pelvis. Extravasated contrast material can be distinguished from clotted blood by measuring CT attenuation. CT accurately shows the anatomic location of bleeding and indicates the probable vascular origin. CT, therefore, can be used as a guide for angiographic or surgical intervention.
