. To determine the cost-effectiveness of routine protocol-driven pelvic radiography in the evaluation of blunt trauma patients. ⋯ Trauma protocol-driven pelvic radiography is a necessary and cost-effective means of identifying acute pelvic injury in all trauma patients regardless of clinical presentation.

To distinguish between benign and malignant tumors in the peripheral nerves. ⋯ Absence of severe motor weakness and a central enhancement pattern strongly suggest a benign nature, while severe rest pain and invasive tumor margin suggest malignant lesions in peripheral nerve tumors.

Review Comparative Study
Magnetic resonance imaging in the evaluation of ligament injuries.
Magnetic resonance imaging has had a dramatic effect on the means by which we diagnose ligament injuries. Tears resulting from either acute trauma or overuse can be detected noninvasively, directing appropriate therapy be it conservative or surgical. For the elite athlete, earlier diagnosis leads to earlier intervention, or alternatively, a normal MRI examination can result in an earlier return to play. While MRI is accepted for the diagnosis of certain injuries such as complete tears of the cruciate ligaments of the knee, other injuries, such as partial cruciate ligament tears or tears of the intercarpal ligaments of the wrist, remain controversial.

Comparative Study
A comparison of bone scintigraphy and MRI in the early diagnosis of the occult scaphoid waist fracture.
To determine the accuracy of MRI in the assessment of the radiographically occult scaphoid fracture. ⋯ Six patients (14%) had scaphoid waist fractures. There were other bony injuries in a further six. In 40 patients there was agreement between the BS and MRI findings. In three cases there was discrepancy between the imaging modalities; in all three MRI was found to be the more sensitive and specific. MRI could become the investigation of choice for this injury.

To compare the evaluation of fractures of the distal radius with MRI and conventional radiographs. To demonstrate the ability of MRI to detect unsuspected soft tissue derangement accompanying this common injury. ⋯ MRI affords better evaluation of osseous injury accompanying distal radial fractures than conventional radiographs. Intra-articular soft tissue injury accompanies distal radial fractures in almost 50% of cases. Scapholunate ligament disruption commonly accompanies intraarticular fracture through the lunate facet of the distal radius. Fracture of the ulnar styloid is infrequently associated with tear of the triangular fibrocartilage.
