Sensitivity and Positive Predictive Value for Imaging Studies to Detect Primary Gastrinoma^*

	MR imaging					MR imaging, CT, and US
Index	T1	STIR	Tl/STIR	US	CT	MR imaging, CT, and US	ANGIO
Sensitivity (%)	25	22	25	19	28	38	59
Positive predictive value (%)	89	88	89	75	100	85	92

Sensitivity and positive predictive values were calculated as described in Materials and Methods. Only two patients undergoing surgery had no tumor found at surgery; therefore, there were insufficient numbers of patients without tumors found to calculate reliably specificity or negative predictive value.
