ROC curve for 68Ga-DOTA-TATE PET/CT in general. (A) AUC of SUVR was 0.887 (95% CI: 0.804 to 0.969). (B) AUC of KS was 0.896 (95% CI: 0.819 to 0.973). ROC, receiver operating characteristic; 68Ga-DOTA-TATE, 68Ga-DOTA(0)-Tyr(3)-octreotate; AUC, area under the curve; SUVR, ratio between the SUVmax of the lesion and the SUVmean of the liver; SUVmax, maximal standardized uptake value; SUVmean, mean standardized uptake value; KS, Krenning scale; CI, confidence interval.
