Abstract:
Objective To investigate the application of automatic tube voltage selection (CARE-kV)coronary CT angiography (CCTA)using ultra-low contrast media (CM)protocols in patients with body mass index (BMI)between 20 kg/mand 30 kg/mon third-generation dual-source CT (DSCT). Methods We prospectively included 134 consecutive patients with BMI between 20 kg/mand 30 kg/mwho underwent CARE-kV prospective high-pitch CCTA on third-generation DSCT using the ultra-low CM protocols and divided them into two groups according to the CARE-kV results:70 kV group(n=91):65 patients with normal BMI(20 kg/m≤BMI≤25 kg/m)and 26 patients with high BMI(25 kg/m
