An evaluation of 99mTc-sulfur colloid liver scintiscans and their usefulness in metastatic workup: a review of 1,424 studies.

To determine the clinical usefulness of liver scintiscanning in detecting metastatic disease of the liver, 1,424 liver studies performed on 1,115 patients were reviewed along with their charts. Five hundred eighty-one patients had histopathological evaluation by needle biopsy of the liver, laparotomy, and/or autopsy within a mean period of 40 days of liver scan. The histopatholigical findings were correlated with the liver sicntiscan findings and the latter gave an overall accuracy of 77.3%.
