A survey of the literature pertaining to several serial brain scanning procedures has been presented. These procedures include rapid brain imaging, sequential brain imaging, delayed from imaging, and follow-up brain imaging. Applications of these techniques to specific clinical problems have been stressed and the reported results reviewed. Thus, it has been indicated that rapid brain imaging is most useful in detecting lesions secondary to cerebrovascular disease but may also provide some helpful information pertaining to the differential diagnosis of other C.N.S. lesions demonstrated on subsequent static brain scans. Sequential brain imaging is a time-consuming adjunctive procedure which, however, can be extraordinarily helpful in a highly selected group of problem cases which present with relatively small lesions adjacent to normal anatomic structures which themselves have considerable radioactivity. Delayed brain imaging has the distinction of detecting the greatest number of intracranial lesions but is attended by tactical problems in maintaining an optimal patient flow through the department and also has the undesirable consequence of reduced information density and diminished image quality, unless greater radiation doses are injected. Follow-up brain imaging is useful in the differential diagnosis of cerebrovascular and neoplastic disease and in the assessment of effectiveness of radiation therapy.
本文对与几种连续脑部扫描程序相关的文献进行了综述。这些程序包括快速脑部成像、序贯脑部成像、延迟成像和随访脑部成像。着重介绍了这些技术在特定临床问题中的应用，并对报告结果进行了回顾。因此，已表明快速脑部成像在检测脑血管疾病继发的病变方面最为有用，但也可能为后续静态脑部扫描中显示的其他中枢神经系统病变的鉴别诊断提供一些有用信息。序贯脑部成像是一种耗时的辅助程序，然而，在一组经过高度筛选的疑难病例中，它可能非常有帮助，这些病例存在与本身具有相当放射性的正常解剖结构相邻的相对较小的病变。延迟脑部成像的特点是能检测到最多的颅内病变，但在保持患者在科室的最佳流动方面存在策略性问题，而且除非注入更大的辐射剂量，否则会产生信息密度降低和图像质量下降的不良后果。随访脑部成像在脑血管和肿瘤疾病的鉴别诊断以及放射治疗效果评估中很有用。
