Liver scans in evaluation of lesions of the diaphragm

Three patients had chest radiographs suggesting pathology associated with the right hemidiaphragm. The patients' histories included trauma in one case, recently diagnosed leukemia in a second, and Hodgkin's disease in the third. In all three cases, the Tc-99m-sulfur colloid liver scan provided a noninvasive identification of the nature of the diaphragmatic densities seen on the chest radiographs, thus affecting patient management
