To determine the frequency of unsuspected pelvic fracture and soft-tissue injury in patients referred for magnetic resonance (MR) imaging for possible radiographically occult hip fracture. ⋯ A high prevalence of occult pelvic fracture and soft-tissue injury may be identified with MR studies designed to evaluate occult hip fracture when large-field-of-view T1-weighted coronal sequences are combined with T2-weighted or STIR sequences.

To correlate the histologic structure and echotexture of peripheral nerves and verify if ultrasound (US) findings can be used to differentiate nerve from tendon. ⋯ Peripheral nerves have a typical US pattern that correlates with histologic structure and facilitates differentiation between nerves and tendons.
-
To evaluate the usefulness of routine performance of computed tomography (CT) of the craniocervical junction in unconscious patients with substantial head injury. ⋯ Because 5.4% of all patients had fractures of either C-1 or C-2 and 4.0% had occipital condyle fractures not seen at plain radiography, routine additional performance of CT of the craniocervical junction is useful in patients with substantial cranial trauma.

To assess if the initial grade of splenic injury depicted at computed tomography (CT) in children could help predict rate of healing. ⋯ CT grade of splenic injury is related to rate of healing. Grade 1 and 2 injuries typically heal within 4 months, whereas grade 3 injuries take up to 6 months to heal and grade 4 injuries take up to 11 months.
