Assessment of incidental focal colorectal uptake by analysis of fluorine-18 fluorodeoxyglucose positron emission tomography parameters

Figure 3 Receiver operating characteristic curves. Receiver operating characteristic (ROC) curves of the maximum standardized uptake value (SUV) and mean SUV of metabolic tumor volume 3.5 of malignant/premalignant lesions. The values of area under the curve are 0.770 and 0.763 and the cut-offs are 7.6 [confidence interval (CI) 0.668-0.0.872, sensitivity 0.686, specificity 0.688] and 4.9 (CI 0.658-0.867, sensitivity 0.667, specificity 0.656), respectively.
