A comparison o CT (computerized Tomography) and radionuclide brain scanning was performed; 30 patients with a total of 42 lesions were evaluated. Previous sreports have shown that CT and radionuclide scanning are equally useful in detecting metastatic disease. However, if contrast enhancement is used we find that computerized tomography is far more accurate than radionuclide scanning in detecting metastatic disease to the brain, 95.4 percent as compared to 62 percent. Our study also shows that radionuclide scanning falls off in accuracy when the the lesion is below 2 cm. in size. Also, the presence of brain edema in association with metastatic disease increases the probability of having a positive nuclear scan finding.
