In this experimental study, the usefulness of a new radiotracer, Tc-99m pyridoxal-phenylalanine ("Tc-PPh"), is evaluated as a hepatobiliary imaging agent, and results are compared with those of conventional cholangiography. In the presence of a normal biliary tree or in cholelithiasis, information derived from conventional cholangiography is of better quality. The radiotracer technique, however, is very useful for the demonstration of cholopeptic bypass procedures, even in the presence of jaundice, and also in cases of intraperitoneal bile leakage. |
