Estimating Risk of Cancer Associated With Radiation Exposure From 64-Slice Computed Tomography Coronary Angiography

Cancer-Prone Mice Expressing the Ki-rasG12CGene Show Increased Lung Carcinogenesis after CT Screening Exposures

“…4). This observation is consistent with other data showing that females are often more radiosensitive than males (2, 4, 29, 30). …”

Gender based lung cancer risks for symptomatic coronary artery disease patients undergone cardiac CT

“…The LAR for lung cancer for female patients has also been found to be greater than for males in all age groups which may also be due to differences in radio-sensitivities as well as the amount of radiation exposure. Similar observations have been made in the study conducted by Einstein et al [ 13 ]. Recent studies like Karimizarchi & Chaparian [ 35 ] and Mahmoodi & Chaparian [ 36 ]; demonstrated similar findings in the sense that cancer induced risk is a variation of age and gender where younger females are at a higher risk.…”

Individualized Assessment of Radiation Dose in Patients Undergoing Coronary Computed Tomographic Angiography With 256-Slice Scanning

“…3,5,7 The effective dose from CCTA performed on 256-slice scanners in the prospective mode is Ϸ4 times lower than corresponding values for studies performed on 64-slice CT scanners in the retrospective mode. Consistent with published data, 31 CCTA-related cancer LAR is markedly higher for women and decreases with patient age, as shown in Figure 2, with the decrease being much steeper for women. This is attributed to the inclusion of the female breast in the primarily exposed body region.…”
