Prospective-triggered high-pitch spiral versus sequential dual-source CT coronary angiography: comparison of image quality and radiation dose

ABSTRACT

Background: prospectively electrocardiography [ECG]-triggered high-pitch spiral coronary computed tomography angiography [CCTA] is a unique scan mode for dual -source CT [DSCT]. Our reports aim to compare image quality and radiation dose of CCTA using high-pitch spiral or sequential acquisition mode in patients with low and stable heart rates
