The usefulness of sequential scanning, three and 24 hours after injection of 197Hg chlormerodrin in the detection of metastatic tumors of the brain has been demonstrated. The 24-hour scan was positive in 29% of the cases in which a metastatic lesion was suspected although the three-hour scan was negative, and the 24-hour scan also revealed additional masses in another 20%. The delayed scan helped to demarcate the actual location of the lesion in 24% of the cases in which the three-hour scan was graded merely suspicious. It is concluded that the addition of a 24-hour scan strongly reinforces the statistical accuracy of the 197Hg brain scan, and thus is of practical clinical importance.
注射197汞氯汞丙脲后三小时和二十四小时进行连续扫描在检测脑转移瘤方面的有效性已得到证实。在怀疑有转移病变但三小时扫描为阴性的病例中，24小时扫描有29%呈阳性，另外20%的病例中24小时扫描还发现了其他肿块。在三小时扫描仅判定为可疑的病例中，延迟扫描在24%的病例中有助于确定病变的实际位置。得出的结论是，增加24小时扫描能大大提高197汞脑扫描的统计准确性，因此具有实际临床意义。
