Abstract EN
Computed tomography angiography (CTA) has become the most valuable imaging modality for the diagnosis of blood vessel diseases; however, patients are exposed to high radiation doses and the probability of cancer and other biological effects is increased.
The objectives of this study were to measure the patient radiation dose during a CTA procedure and to estimate the radiation dose and biological effects.
The study was conducted in two radiology departments equipped with 64-slice CT machines (Aquilion) calibrated according to international protocols.
A total of 152 patients underwent brain, lower limb, chest, abdomen, and pelvis examinations.
The effective radiation dose was estimated using ImPACT scan software.
Cancer and biological risks were estimated using the International Commission on Radiological Protection (ICRP) conversion factors.
The mean patient dose value per procedure (dose length product [DLP], mGycm) for all examinations was 437.8± 166, 568.8± 194, 516.0± 228, 581.8± 175, and 1082.9± 290 for the lower limbs, pelvis, abdomen, chest, and cerebral, respectively.
The lens of the eye, uterus, and ovaries received high radiation doses compared to thyroid and testis.
The overall patient risk per CTA procedure ranged between 15 and 36 cancer risks per 1 million procedures.
