Positron emission tomography (PET)/CT and sensitivity/specificity analysis. (A) Axial and coronary depiction of PET/CT overlay and PET scan with correspondingly marked region of interest (ROI; red circle) where mean standard uptake value (SUV) is measured. Additional measurements are made in the liver (B) and the ascending aorta (mediastinal blood pool) (C). (D) Receiver-operator curve (ROC) for sensitivity/specificity based on area under the curve (AUC) measurement for SUV_max aorta, SUV_TBR and SUV_TLR. (SE = standard error; CI = confidence interval; cut-off at maximum sensitivity and specificity).
