Figure 4:

Graph shows results of sensitivity analysis of projected days of life expectancy loss from radiation-induced cancer deaths. We varied the projected days of life expectancy loss attributable to radiation-induced cancers from CT from 0 to 6 days. At the base-case value of 1.7 days, MR imaging alone was the preferred strategy. For life expectancy losses attributable to radiation-induced cancers less than a threshold value of 0.023 days, combined US and CT was the preferred strategy.
