MR imaging of pediatric elbow fractures.

Pediatric elbow fractures are elusive to radiographic detection and more sophisticated imaging techniques are often required to assess the presence and extension of the fracture line to make appropriate treatment decisions. Arthrography is the current method of choice, but ultrasonography and, more recently, MR imaging have been proposed as alternative modalities, although further experience is necessary to validate their usefulness. We believe that MR imaging offers significant benefits because of its exquisite spatial and contrast resolution.
