Diagnosis of brain tumors. A comparison of photoscanning and neuroradiological techniques.

Results of radioisotope photoscans and diagnostic neuroradiological procedures performed in 167 patients with suspected brain tumors led to the conclusion that correct identification of the intracranial process can be obtained in a high proportion of cases by the proper selection of available diagnostic techniques. The radioisotope photoscan had a relative diagnostic accuracy nearly equal to that of the neuroradiological techniques. The accuracy, taken with the relative ease and safety of the method, make it an ideal screening procedure in cases in which intracranial pathologic change is suspected.
