Performance of dual-source CT with high pitch spiral mode for coronary stent patency compared with invasive coronary angiography.

Objective: To investigate the performance of dual-source computed tomography (DSCT) using high-pitch spiral (HPS) mode for coronary stents patency.

Methods: We conducted a prospective study on 120 patients with 260 previous stents implanted due to recurred suspicious symptoms of angina scheduled for invasive coronary angiography (ICA), while DSCT were conducted using HPS mode.

Results: There was no significant impact of age, body mass index or heat rate (HR) on image quality ( > 0.
