Dynamic bloodflow studies of space-occupying lesions in the liver

Abstract

Blood flow to space-occupying lesions in the liver was studied by scintillation camera in a series of 170 patients after injection of ^113mIn-colloid. The curves obtained show a biphasic curve over the normal liver, absence of portal flow over a malignant lesion, and avascularity over benign lesions such as cysts or abscesses. The usefulness and limitations of this technique in distinguishing between a benign and malignant lesion in the liver are discussed.
