Sequential brain scans were performed at various time intervals of up to four hours after injection of 99mTc pertechnetate in 108 patients who had previously undergone "routine" one-hour brain scans which were considered normal or equivocal. Forty-six patients were proved to have a discrete morphologic brain lesion. Pathologic processes were demonstrated by the sequential scanning technique in all but 6 cases. In nearly a third of these 46 patients (28%), careful observation of the progressive and subtle changes in radioactivity in the whole sequential scan series was necessary for detection of the lesions: they could not be appreciated on any single static scan when viewed independently.
对108例先前接受过“常规”1小时脑部扫描且结果被认为正常或不明确的患者，在注射高锝[99mTc]酸盐后长达4小时的不同时间间隔进行了连续脑部扫描。46例患者被证实有离散的形态学脑部病变。除6例病例外，连续扫描技术在所有病例中均显示出病理过程。在这46例患者中，近三分之一（28%）的病例需要仔细观察整个连续扫描系列中放射性的渐进性和细微变化才能检测到病变：单独查看任何一张静态扫描图像时都无法识别这些病变。
