ABSTRACT
Objective To investigate the value of optimizing the thoracic CT scanning dose on reducing radiation dose.Methods 50 patients were undergone CT scanning using CARE Dose 4D technique,the mAs of each slices,CT dose index of volume(CTDIvol) and images qualities were evaluated respectively.And the results were compared with traditional thoracic CT scanning(200mAs,15.31mGy).Results Compared with routine sequence,the exposure dose of singe-slice was decreased by 48.2% when the CARE Dose 4D technique was used(maximal decreasing 84%),CTDIvol was reduced about 32.98%(maximal reduction of 56.5%),there was statistically significant difference(P
