title: Accuracy of radionuclide imaging in distinguishing renal masses from normal variants.
abstract: To determine the accuracy of scintigraphy in distinguishing true renal masses from normal variants, 40 patients with excretory urographic findings indicating a possible, but not definite, mass lesion were studied. Scintigraphy correctly identified 17 true masses and 17 normal variants. Four false positive and two false negative results were obtained.
