Computed tomography and radionuclide studies in the diagnosis of intracranial disease

The accuracy of CT and radionuclide studies in the diagnosis of intracranial disease is analyzed based on experience in 641 patients. Results indicate that both modalities give reasonably similar precision and that a modest improvement in diagnosis can be expected if both techniques are employed. It is emphasized that the radionuclide studies used routinely included what are rightfully considered adjunctive scanning procedures, so that results must be considered in this light
