Scintigraphy in the Diagnosis of Hepatocellular Carcinoma
The introduction of hepatic scintigraphy in the late 1950s represented a major advance in the diagnosis of focal hepatic lesions because it became possible for the first time to obtain images of the liver with a noninvasive procedure. Several years were to elapse before alternative and perhaps better hepatic imaging modalities became available, and during this time radio-tracer scanning proved to be invaluable, both in the recognition of hepatocellular carcinoma and in the evaluation of patients with this tumor. Scintigraphy was used to confirm (or in some patients to establish) the presence of a “space-occupying lesion” in the liver, to provide a reasonably accurate assessment of the size, position, the extent of the tumor when resectability was being considered, and to determine the optimal site for percutaneous biopsy of the lesion.
