To compare the effectiveness and safety of oral (PO) versus intravenous (IV) pentobarbital sedation for magnetic resonance (MR) imaging and computed tomography (CT) in infants younger than 12 months. ⋯ PO pentobarbital has comparable effectiveness and a lower rate of respiratory complications compared with IV pentobarbital in infants younger than 12 months; its use should be considered, regardless of presence of an IV catheter.
-
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.
