Low Dose Computed Tomography

The use of computed tomography is increasing rapidly and doses are not negligible especially when medical procedures require more than one scan. The purpose of the present study was to measure doses in an anthropomorphic Rando phantom during a standard and low dose computed tomography protocol of the thorax and to estimate risks of radiation induced cancer for adult patients that undergo multiple computed tomography scans of the thorax. Thermoluminescent and radiophotoluminescent dosimeters were used for dose measurements. Radiation risks of cancer incidence, in the form of lifetime attributable risk, were estimated using the BEIR VII model. For five exposures with the standard protocol mean organ doses were 94 mGy (breast), 85 mGy (stomach), 85 mGy (thyroid), 78 mGy (lung), 52 mGy (liver), and 16 mGy (colon). Associated lifetime attributable risk were found to be up to 0.401 % (401 breast cancers per 100 000 exposed patients) and 0.116 % (116 lung cancers per 100 000 exposed patients) for female and male, respectively. A low dose protocol reduces doses (and risks) by the average factor of 5 and therefore the use of a low dose protocol is recommended whenever it is medicaly justified.

Abstract The aim of this study is the calculation of equivalent organ dose and estimation of lifetime attributable risk (LAR) of cancer incidence and mortality related to cardiac computed tomography angiography (CCTA) because the use of CT angiography as a noninvasive diagnostic method has increased. The organ dose has been calculated by ImPACT software based on the volumetric CT dose index (CTDIvol), and LAR of cancer risk incidence and mortality from CCTA has estimated according to the BEIR VII report. The median value of the effective dose was 13.78 ± 6.88 mSv for both genders. In all scanners, the highest median value for LAR of cancer incidence in males and females for lung cancer was 44.20 and 109.17 per 100 000, respectively. And in infants was 5.89 and 12 for lung cancer in males and breast cancer in females, respectively. Also, the median value of LAR of all cancer incidence from single CCTA in adult patients for males and females was 122 and 238 cases, respectively. Maximum LAR of cancer mortality in adults for lung cancer was 40.28 and 91.84 and in pediatrics was 5.69 and 8.50 in males and females, respectively. Despite many benefits of CTA in the heart disease evaluation, according to a high radiation dose in CCTA, to reduce the cancer risk: CCTA should be used cautiously, especially for pediatric and females.
