This study investigated the clinical role of 201Tl brain SPECT imaging in assessing the histologic grade of brain tumors. Methods Early and delayed brain SPECT imaging was performed at about 10 min and 3 h after intravenous injection of 111 MBq of 201 Tl. 9 healthy volunteers, 3 cerebral hematomas and 41 patients with brain tumors. All patients and healthy volunteers received semi-quantitative data of early and delayed 201 Tl uptake index and 201 Tl retention index. Results of 9 cases of health
