Results: Based on the reference standard 13 of 35 patients had NET. Ga-68 DOTATATE PET/CT was positive in 12 out of 13 patients and it was false negative in 1 patient. Pancreas was the commonest site of the primary tumor. Ga-68 DOTATATE was TP(true pozitive), FP (False Positive), TN (True Negative) and FN (False Negative) in, 12, 2, 20 and 1, patients respectively. Sensitivity, specificity, Pozitive Pedictive Value (PPV), Negative Pedictive Value (NPV), and accuracy of Ga-68 DOTATATE PET/CT was calculated as 85%, 95%, 92%, 90% and 91%, respectively.
