Fig. 2. — Relative risk of infections with treatment- and radiation-induced cancer. The risk of mortality due to infections (TB as an example) compared to the risk of radiation-induced cancer due to commonly used imaging techniques. The risk of mortality for MDR- and XDR-TB patients on treatment is similar to that due to cancers. Even drug-susceptible TB patients on treatment have significantly higher risk of mortality than radiation-induced cancers with optimized imaging. The risk of radiation-induced cancer and mortality has been theoretically estimated based on acute radiation exposure (100 mSv), and actual risks are likely to be much lower for smaller amounts of radiation.
