In this study we evaluate radiation dose from a prospective ECG-triggered coronary CT angiography (CCTA) examination multidetector 640-slice CT and compares with other establish references. A total of 98 patient subjects were fall into inclusion criteria and related parameters has been recorded and analysed. It was estimated that the effective dose was at 5.23 ± 4.38 mSv (range 1.34 to 20.35 mSv) and it was significantly lower than that stated in the national dose reference level (NDRL) with 57% difference. It is highly recommended that the practice of using prospective ECG-triggering CCTA with low scanning range provides an optimum amount of radiation dose when compared to previous practice.
