Comparison of Octreo-SPECT and FDG PET/CT in localizing mesenchymal tumors in TIO.

	Tumor Positive	Tumor Negative	Total
Octreo-SPECT positive	18	4	21	Sensitivity	0.95
Octreo-SPECT negative	1	7	9	Specificity	0.64
Total	19	11		PPV	0.82
				NPV	0.88

FDG PET/CT positive	14	7	21	Sensitivity	0.88
FDG PET/CT negative	2	4	6	Specificity	0.36
Total	16	11		PPV	0.62
				NPV	0.50

Octreo-SPECT, = ¹¹¹Indium-octreotide with single photon emission computed tomography FDG PET/CT = ¹⁸fluorodeoxyglucose positron emission tomography/CT , PPV = positive predictive value, NPV = negative predictive value
