Image quality and radiation exposure with a low tube voltage protocol for coronary CT angiography results of the PROTECTION II Trial.

Objectives: The purpose of this study was to evaluate image quality and radiation dose using a 100 kVp tube voltage scan protocol compared with standard 120 kVp for coronary computed tomography angiography (CTA).

Background: Concerns have been raised about radiation exposure during coronary CTA. The use of a 100 kVp tube voltage scan protocol effectively lowers coronary CTA radiation dose compared with standard 120 kVp, but it is unknown whether image quality is maintained.

Endovascular management of inadvertent subclavian artery catheterization during subclavian vein cannulation.

Purpose: To retrospectively review a 9-year experience with endovascular management of inadvertent subclavian artery catheterization during subclavian vein cannulation.

Materials And Methods: From June 2000 through July 2009 (109 months), 13 patients underwent endovascular management of inadvertent subclavian artery catheterization. All catheters were still in situ, including one 7-F catheter, six 8-F catheters, and six large-bore 10-11-F catheters.

Biliary infections: spectrum of imaging findings and management.

Infectious cholangitides encompass a wide spectrum of infectious processes affecting the biliary tree. They can have protean clinical and imaging appearances. Some manifest as an acute medical emergency with high mortality if not properly and emergently managed.

Initial clinical experience with a 64-MDCT whole-body scanner in an emergency department: better time management and diagnostic quality?

Background: The objective of this study was to assess time management and diagnostic quality when using a 64-multidetector-row computed tomography (MDCT) whole-body scanner to evaluate polytraumatized patients in an emergency department.

Methods: Eighty-eight consecutive polytraumatized patients with injury severity score (ISS) > or = 18 (mean ISS = 29) were included in this study. Documented and evaluated data were crash history, trauma mechanism, number and pattern of injuries, injury severity, diagnostics, time flow, and missed diagnoses.

Endovascular repair or medical treatment of acute type B aortic dissection? A comparison.

Introduction: The aim of this retrospective study was to compare the outcome of thoracic endovascular aortic repair (TEVAR) to that of medical therapy in patients with acute type B aortic dissection (TBD).

Materials And Methods: From July 1996 to April 2008, 88 patients presenting with acute TBD underwent either TEVAR (group A, n=38) or medical therapy (group B, n=50). Indications for TEVAR were intractable pain, aortic branch compromise resulting in end-organ ischemia, rapid aortic dilatation and rupture.
