In a series of 23 patients with surgically proven subdural hematoma of durations ranging between two days to seven months, the detection rate of Tc-99m-pertechnetate brain imaging was higher than computerized transaxial tomography (CT). With dynamic perfusion scanning, the detection rate was 71.5%. However, when combined with sequential static images obtained at 10 minutes, 2 hours and 3--4 hours, the detection rate rose to 92% regardless of the duration of the disease. In contrast, CT demonstrated the hematoma in 52% of the cases. In another 28% the diagnosis was suggested through nonconclusive evidence or presence of contralateral shift of midline structures. Lastly, the result of CT scanning was dependent on the size of the subdural hematoma as evaluated at the time of operation.
在一系列23例经手术证实的硬膜下血肿患者中，血肿持续时间在两天至七个月之间，锝-99m高锝酸盐脑显像的检出率高于计算机断层扫描（CT）。动态灌注扫描时，检出率为71.5%。然而，当结合在10分钟、2小时和3 - 4小时获得的序贯静态图像时，无论病程长短，检出率均升至92%。相比之下，CT在52%的病例中显示出血肿。另外28%的病例通过非确定性证据或中线结构对侧移位提示诊断。最后，CT扫描结果取决于手术时评估的硬膜下血肿大小。
