To retrospectively evaluate multi-detector row computed tomography (CT) without oral contrast material for depiction of bowel and mesenteric injuries that require surgical repair in patients with blunt abdominal trauma. ⋯ Multi-detector row CT without oral contrast material is adequate for depiction of bowel and mesenteric injuries that require surgical repair. Results are comparable with previously reported data for single-detector row helical CT with oral contrast material.

To determine diagnostic accuracy of four-channel multi-detector row computed tomography (CT) in emergency room and inpatient populations suspected of having acute pulmonary embolism (PE) who prospectively underwent both CT and pulmonary arteriography (PA). ⋯ Multi-detector row CT has an accuracy of 91% in the depiction of suspected acute PE when conventional PA is used as the reference standard.

Comparative Study
Bronchial and nonbronchial systemic arteries at multi-detector row CT angiography: comparison with conventional angiography.
To retrospectively evaluate bronchial and nonbronchial systemic arteries at multi-detector row helical computed tomography (CT) compared with conventional angiography in patients undergoing endovascular treatment of hemoptysis. ⋯ Multi-detector row helical CT angiography provides more precise depiction of bronchial and nonbronchial systemic arteries than does conventional angiography.

To evaluate resonant circuits as markers for magnetic resonance (MR) imaging-guided placement of nitinol stents. ⋯ Resonant circuits are well suited for use at deployment of endovascular stents.

To retrospectively review the authors' experience with a radiologic method of primary insertion of a skin-level gastrostomy tube (Entristar; Tyco Healthcare, Mansfield, Mass) in patients with amyotrophic lateral sclerosis (ALS). ⋯ Radiologically guided insertion of the Entristar skin-level gastrostomy tube is a safe procedure in patients with ALS that allows the creation of a permanent feeding gastrostomy without the need for sedation or endoscopy.
