This study investigated the clinical usefulness of evaluating the histologic grade of brain tumors by ^sup 201^T1 SPECT brain imaging. Methods: Early and delayed SPECT brain images were obtained about 10 min and 3 h, respectively, after intravenous injection of 111MBq (3 MCi) ^sup 201^T1 in 9 healthy subjects (control subjects), 3 patients with brain hematomas, and 41 patients with brain tumors. Semiquantitative data were obtained for early and delayed ^sup 201^T1 uptake indices and ^sup 201^T1 retained index in all patients and healthy subjects. Results: In 9 healthy subjects, there was little radioactivity in brain substance. In all patients with brain hematomas or tumors, a high tracer ...
