Impact of an ultra-low dose unenhanced planning scan on CT coronary angiography scan length and effective radiation dose

OBJECTIVE: Imaged scan length (z-axis coverage) is a simple parameter that can reduce CT dose without compromising image quality. In CT coronary angiography (CTCA), z-axis coverage may be planned using non-contrast calcium score scan (CaCS) to identify the relevant coronary anatomy. However, standar...
