Abstract

PURPOSE: The purpose of our study was to compare coronary luminal diameters in patients undergoing coronary computed tomography angiography (CCTA) performed with different sublingual nitroglycerin (NTG) spray regimens. MATERIALS AND METHODS: We retrospectively reviewed CCTA studies performed in two historical groups (Group 1, single dose nitroglycerin 2 min prior to CCTA, and Group 2, single dose 10 min prior), and a current protocol group (Group 3, single dose at 2 and 10 min prior). Thirty patients were evaluated per group. Two blinded readers measured coronary luminal diameters with comparison of diameter measurements. A third blinded reader assessed image quality of coronary artery segme..
