Abnormal brain scans: Contribution of blood radioactivity to image.
Images obtained with 99m-Tc-labeled red blood cells were compared with 99m-Tc-pertechnetate scans in 26 patients with primary and secondary brain tumors, intracerebral infcts, and hemorrhage. The results indicated that the contribution of blood pool radioactivity to a positive brain scan was minor.
