Specificity of somatostatin receptor scintigraphy: a prospective study and effects of false-positive localizations on management in patients with gastrinomas.

Abstract

False-positive SRS localization occurs in 1 of 10 patients with ZES. By having a thorough understanding of diseases or circumstances that result in false-positive localization and comparing the SRS result with the clinical context, the percentage of patients in whom false-positive localization results in altered management can be reduced to below 3% and the correct diagnosis made in almost every case.
