Objectives This study aimed to measure the absorbed doses in selected organs for
prospectively ECG-triggered coronary computed tomography angiography (CCTA) using …

OBJECTIVE: To compare radiation doses delivered at prospectively ECG-triggered
sequential-(SEQ), retrospectively ECG-gated spiral-(RETRO) and prospectively ECG …

Computed tomography coronary angiography (CTCA) has generated tremendous interest
over the past 20 years by using multidetector computed tomography (MDCT) because of its …

In recent years, with the introduction of 64-slice CT and dual-source CT technology,
coronary CT angiography (CCTA) has emerged as a useful diagnostic imaging modality as …

Background Though appropriate image acquisition parameters allow an effective dose
below 1 mSv for CT coronary angiography (CTCA) performed with the latest dual-source CT …

A retrospective analysis was performed in patients undergoing prospective ECG-triggered
coronary computed tomography (CT) angiography (CCTA) with the single-source 64-slice …

Cardiac computed tomography angiography (CCTA) is a commonly used diagnostic tool for
cardiovascular disease. Despite constant improvements to imaging technologies, the …

In this report we have evaluated radiation effective dose received by patients during ECG-
gated CCTA examinations based on gender, heart rate, tube voltage protocol and body …

PURPOSE: To estimate the effective dose of cardiac CT with different dose saving strategies
dependent on varying heart rates. MATERIALS AND METHODS: For dose measurements …

The objective of this study was to propose diagnostic reference levels (DRLs) for coronary
computed tomography angiography (CCTA), in the context of a large variability in patient …
