Computed tomography (CT) examinations have become increasingly popular because of recent multidetector technological developments; concerns have arisen over the increase in the patient dose. We aimed to evaluate the impact of automatic tube current modulation (ATCM) technique in CT multiphasic examinations based on the radiation dose and image quality compared to fixed tube current (FTC) technique. We retrospectively reviewed the images of 50 patients who
underwent multiphasic CT of the liver using a 160 slice CT scanner. The study was performed following scan steps according to hepatic circulatory phases namely arterial, portal, venous, and equilibrium phases. All phases are done using identical scan and reconstruction parameters except for the tube current. The portal phase was... view more»
