OBJECTIVE. The objective of our study was to evaluate radiation dose and quantitative
image quality parameters at high-pitch CT angiography (CTA) of the aorta compared with …

Objective To assess the image quality of aorta obtained by dual-source computed
tomography angiography (DSCTA), performed with high pitch, low tube voltage, and low …

Purpose Ionizing radiation and iodinated contrast media are potential drawbacks to
repetitive follow-up CT angiography in current practice. The aim of the present study was to …

Aim To evaluate the impact of a “double-low “imaging protocol (low tube voltage and low
contrast agent concentration) on image quality and radiation dose for aortic computed …

The purpose of this study was to investigate the effects of a prospective ECG-gated, low
kilovoltage and low mAs protocol on image quality and radiation dose when acquiring CT …

Rationale and Objectives To assess the feasibility of 70-kVp high-pitch non–ECG-gated
thoracic aortic computed tomography angiography (CTA) with 40-mL contrast agent …

OBJECTIVE. We sought to compare image quality, contrast enhancement, and radiation
dose in patients undergoing ECG-triggered high-pitch helical CT or non–ECG-synchronized …

PURPOSE: To compare ECG-gated and non-gated CT angiography of the aorta at the same
radiation dose, with regard to motion artifacts (MA), diagnostic confidence (DC) and signal-to …

Purpose To prospectively develop individualized low-volume contrast media (CM) protocols
adapted to tube voltage in patients undergoing computed tomographic (CT) angiography of …
