Abdominal Computed Tomography Angiography at 80kV: feasibility study.

Purpose: preliminary evaluation of different dose reduction algorithms in abdominal Computed Tomography Angiography (CTA) with standard scan protocols at 120kV vs. 80kV.

Materials And Methods: prospective, randomized, crossover study.

Under-reporting of cardiovascular findings on chest CT.

Purpose: It is unclear whether (and, to what extent) radiologists look at and report cardiovascular abnormalities on non-cardio-synchronized standard chest computed tomography (CT). In this study, the frequency and the reporting rate of cardiovascular findings in chest CT examinations were retrospectively assessed.

Materials And Methods: This study was approved by the institutional review board of each participating center.

Collateral non cardiac findings in clinical routine CT coronary angiography: results from a multi-center registry.

Purpose: The aim of the study was to evaluate the prevalence of collateral findings detected in computed tomography coronary angiography (CTCA) in a multi-center registry.

Materials And Methods: We performed a retrospective review of 4303 patients (2719 males, mean age 60.3 ± 10.

Coronary CT angiography using iterative reconstruction vs. filtered back projection: evaluation of image quality.

Objectives: To compare image quality of iterative reconstruction algorithm(IRIS) vs. standard filtered back projection(FBP) reconstruction in CT Coronary Angiography (CTCA).

Materials And Methods: Thirty-four consecutive patients underwent CTCA for suspected or known CAD with Dual-Source CT (DSCT-Flash, Siemens).

Carotid intima media thickness and coronary atherosclerosis linkage in symptomatic intermediate risk patients evaluated by coronary computed tomography angiography.

Background: There is a growing evidence that carotid intima media thickness (CIMT) is associated with coronary artery disease (CAD) and it should be used as a predictor of atherosclerotic burden of coronary arteries. However, these studies have been performed by using invasive coronary angiography (ICA) and in high-risk patients for CAD. The purpose of this study was to evaluate the correlation between CIMT by ultrasound and coronary atherosclerosis in symptomatic intermediate risk patients by coronary computed tomography angiography (CCTA).
