摘要
The aim of the current study was to investigate the effect of cardiologists' experience on the patient received dose during coronary angiography. The exposure parameters including fluoroscopy time, total kerma-area product (KAP), total air-kerma, fluoroscopy and cine acquisition KAP and air-kerma for five senior cardiologists with the experience of 6-10 y were recorded. The range of values for fluoroscopy time and total KAP were 2.17- 4.19 min and 12.06-21.06 Gy cm(2), respectively, in our diagnostic coronary examinations, which was below the recommended reference values. The differences among cardiologists were analysed statistically using one-way ANOVA test. The fluoroscopy KAP and air-kerma results showed statistically significant differences between cardiologists. However, the experience of the cardiologists showed no relation with patient received dose. According to the results, training in radiation protection as a requisite for interventional cardiologists was recommended.
