Clinical Application of Colour Modulation of Gamma Energy and Depth by Dual-Channel Scanning

Abstract

A dual-channel scanning system has been described permitting the simultaneous imaging in individual color of the distribution of two gamma-emitting radioisotopes. In those cases where two organs are adjacent and concentrate the same isotope, they may be displayed in separate color if one of the organs concentrates another gamma-emitting isotope with a different energy. This is accomplished by individual color readout of this isotope and the display of the subtraction of this isotope from the common isotope in another color. By using two facing scintillation probes on either side of the individual being scanned, two overlapping organs at different depths concentrating the same isotope can be color differentiated by a dual-channel playout of each probe. The principal application of these dual-channel scanning methods to date has been the simultaneous display of the liver and pancreas in individual colors using {sup 198}Au and {sup 75}selenomethionine. Characteristic scans have been obtained which differentiate a number of disease states from the normal pancreas and liver. The pancreatic and liver diseases studied and characterized are carcinoma of the pancreas, pancreatic insufficiency, acute recurrent pancreatitis, pancreatic pseudocyst and Laennec's cirrhosis, hepatoma and metastatic malignancy in the liver.

The pancreatic and liver diseases studied and characterized are carcinoma of the pancreas, pancreatic insufficiency, acute recurrent pancreatitis, pancreatic pseudocyst and Laennec's cirrhosis, hepatoma and metastatic malignancy in the liver. The uptake of {sup 75}selenomethionine in malignant lesions in many instances produces positive scans of these tumors in contrasting color to the liver. Depth discrimination in color with the two-probe system has permitted the lateralization of intracranial lesions, the color of the display being proportional to the depth of the lesion. The discrimination of depth and gamma-ray energy by dual-channel color scanning and its general application in visualizing other organs has been accomplished. (author)}
