A retrospective analysis was performed in patients undergoing prospective ECG-triggered coronary computed tomography (CT) angiography (CCTA) with the single-source 64-slice CT (SSCT), dual-source 64-slice CT (DSCT), dual-source 128-slice CT and 320-slice CT with the aim of comparing the radiation dose associated with different CT generations. A total of 164 patients undergoing prospective ECG-triggered CCTA with different types of CT scanners were studied with the mean effective doses estimated at 6.8 ± 3.2, 4.2 ± 1.9, 4.1±0.6 and 3.8 ± 1.4 mSv corresponding to the 128-slice DSCT, 64-slice DSCT, 64-slice SSCT and 320-slice CT scanners. In this study a positive relationship was found between the effective dose and the body mass index (BMI). A low radiation dose is achieved in prospective ECG-triggered CCTA, regardless of the CT scanner generation. BMI is identified as the major factor that has a direct impact on the effective dose associated with prospective ECG-triggered CCTA.

Sabarudin et al. (2012) conducted an observational in Patients undergoing coronary computed tomography angiography (n=164). Prospective ECG-triggered CCTA across different CT scanner generations vs. 64-slice SSCT, 64-slice DSCT, 128-slice DSCT, and 320-slice CT scanners was evaluated on Mean effective radiation dose (mSv). Prospective ECG-triggered CCTA achieved low mean effective radiation doses across 128-slice DSCT, 64-slice DSCT, 64-slice SSCT, and 320-slice CT scanners (6.8, 4.2, 4.1, and 3.8 mSv, respectively).
