Radiography of cervical spine injury in children: are flexion-extension radiographs useful for acute trauma?
We assessed the role of cervical spine flexion-extension radiographs in the acute evaluation of pediatric trauma patients. ⋯ In children with a history of trauma and normal findings on static cervical spine radiographs, additional flexion-extension radiographs are of questionable use.

Usefulness of the double-wall sign in detecting pneumothorax in patients with giant bullous emphysema.
We describe a new sign improving detection of pneumothorax in patients with giant bullous emphysema: air surrounding both sides of the bulla wall (the intrathoracic equivalent of the double-wall sign of pneumoperitoneum). We report the radiographic and CT appearances of the double-wall sign in seven patients with giant bullous emphysema, four of whom had pneumothorax. ⋯ Recognizing the double-wall sign of pneumothorax should aid in the triage of patients with giant bullous emphysema.

Sarcoidosis with pulmonary fibrosis: CT patterns and correlation with pulmonary function.
The purpose of our study was to identify CT patterns of pulmonary fibrosis in patients with sarcoidosis and to correlate these patterns with pulmonary function tests. ⋯ CT may be a useful tool for defining subgroups of patients with fibrotic pulmonary sarcoidosis. CT reveals three main patterns that may reflect different distributions of fibrotic lesions in the lung with different functional pulmonary impairments. The persistence of active pulmonary lesions suggested by the presence of nodular lesions was often associated with linear and distorted patterns.

Single breath-hold T2-weighted MR imaging of the liver: value of single-shot fast spin-echo and multishot spin-echo echoplanar imaging.
The objective of our study was to evaluate the efficacy of single breath-hold T2-weighted MR imaging for detection of focal hepatic lesions. ⋯ Breath-hold single-shot fast spin-echo and multishot spin-echo echoplanar sequences can be substituted for conventional spin-echo and respiratory-triggered fast spin-echo T2-weighted sequences.
