Abstract

Coronary computed tomography (CT) angiography is associated with high radiation dose and this has raised serious concerns in the literature. Awareness of various parameters for dose estimates and measurements of coronary CT angiography plays an important role in increasing our understanding of the radiation exposure to patients, thus, contributing to the implementation of dose-saving strategies. This article provides an overview of the radiation dose quantity and its measurement during coronary CT angiography procedures.

Keywords: Coronary computed tomography angiography; Dose measurement; Dose quantity; Multislice computed tomography; Radiation dose

Core tip: Various dose parameters are used for measurement of radiation dose associated with coronary computed tomography (CT) angiography. It is important to be aware of the dose quantity and measurement in order to achieve the low-dose coronary CT angiography protocol. This article provides an in-depth review of the dose quantity and dose measurement parameters that are commonly used in coronary CT angiography.
