Data are shown as percentage (frequency). CMR indicates cardiac magnetic resonance; FDG, fluorodeoxyglucose; max, maximum; PET, positron emission tomography; SUV, standardized uptake value.
Cutoffs derived (for maximum sensitivity and specificity) from receiver operating characteristic curves shown in Figure 6 (parameter‐based cutoffs as follows; SUVmax 4.44, SUVmean 2.89, hepatic normalized SUVmax 1.05, hepatic normalized SUVmean 1.06, blood pool normalized SUVmax 1.78, blood pool normalized SUVmean 1.35).
