Table 3. Efficiency of 68Ga-DOTA-TATE PET/CT in the differential diagnosis of all PPGLs.
| Methods | Sensitivity | Specificity | Accuracy | PPV | NPV |
|---|---|---|---|---|---|
| SUVR | 68.4% (26/38) | 95.7% (20/21) | 78.0% (46/59) | 96.3% (26/27) | 62.5% (20/32) |
| KS | 71.0% (27/38) | 85.7% (18/21) | 76.3% (45/59) | 90.0% (27/30) | 62.1% (18/29) |
68Ga-DOTA-TATE, 68Ga-DOTA(0)-Tyr(3)-octreotate; PET/CT, positron emission tomography/computed tomography; PPGLs, pheochromocytomas/paragangliomas; PPV, positive predictive value; NPV, negative predictive value; 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 score.
