BMI-Adjusted Tube Current in Chest CT and Comparison of Lifetime Attributable Risk (LAR) of Breast Cancer in Two Different BMI-Based Protocols

Possible strategies to reduce radiation dose during CT scanning have been investigated over recent decades; here the optimization of tube current and its link with patient’s cancer incidence are being evaluated. 154 consecutive trauma patients need for chest scan were included. Two different BMI-adjusted protocols at a fixed voltage same length applied. Dose estimation parameters like index (CTDI), product (DLP) effective breast calculated. Breast surface was obtained by using thermoluminescence dosimeters (TLDs) eventually, life attributable risk (LAR) estimated. The mean 4.87 ± 2.3 mSv 5.12 2.8 who scanned currents 120 mAs 200 mAs, respectively. There no significant difference between organ doses females but in males it notable. is lower protocol 1 comparison 2. Optimizing reduced up 50% mAs. In patients, based on BMI has notable impact absorbed can nearly 33.6% women.
