Computed tomography in metastatic disease of the brain.
Computed tomography has been found to be a more accurate diagnostic tool in the analysis of brain metastases than radionuclide scanning. Of 1,100 patients studied by CT scan, 57 showed evidence of intracerebral metastasis, and 14 showed evidence of hydrocephalus. Density levels below that of normal brain tissue were found in cases of metastases from the lung (13), breast (7), melanoma (4), kidney (3), lymphoma (3), and nasopharynx (1); levels above normal were found in cases of metastases from melanoma (8), lung (3), colon (3), chorionic carcinoma (2), osteogenic sarcoma (1), and kidney (1).
