Detection of space occupying lesions in the liver

Abstract

A method is investigated, which after only one recording session permits the preparation of a series of scintigrams with contrast amplification and varying counting rate cut-off levels. Tests were performed using a triangular nhatom filled with a solution containing the radioactive isotope Au198 , in which spherical objects made from mix-D were placed in various positions. The method was found to enable a definite improvement in the liver scanning technique.
