直到最近，颅内基底池的伦琴检查还需要局部蛛网膜下注射造影剂，无论是阴性还是阳性，其衰减能力与相关解剖结构的衰减能力有很大不同。 HOUNSFIELD (1 9 7 3) 和 AMBROSE (1 9 7 3) 引入的检测和图像重建系统计算机断层扫描可以测量比传统伦琴检查记录的衰减差小约 1 0 0 倍的衰减差。因此，第一次可以在不使用造影剂的情况下区分大脑实质和 CSF 空间。然而，目前基底池与骨性颅底非常接近，限制了识别这些空间的可能性，特别是当它们很狭窄时。 GREITZ & HINDMARSH ( 1 9 7 4 ) 报道，腰椎注射水溶性造影剂后，可以使用计算机断层扫描检查颅内 C S F 循环，因为该介质通过正常的 C S F 循环沿颅方向输送。关于 C S F 动力学的报告结果也表明了该方法在颅内基底池解剖检查方面的诊断潜力。
Until recently roentgen examination of the intracranial basal cisterns required local subarachnoid injection of a contrast medium, negative or positive, which had an attenuation capacity differing considerably from that of the relevant ana tomic structures. A system for detection and image reconstruction, computer tomo graphy, introduced by HOUNSFIELD ( 1 9 7 3 ) and AMBROSE ( 1 9 7 3 ) , permits the mea surement of attenuation differences about 1 0 0 times smaller than those recorded by conventional roentgen examination. Thus, for the first time, cerebral paren chyma and C S F spaces may be distinguished without the use of contrast media. However, the close proximity of the basal cisterns to the bony skull base at present limits the possibilities of discerning these spaces, especially when they are narrow. GREITZ & HINDMARSH ( 1 9 7 4 ) reported that the intracranial C S F circulation could be examined using computed tomography after lumbar injection of a water-soluble contrast medium due to the fact that the medium was transported in the cranial direction by the normal C S F circulation. The results reported concerning the C S F dynamics also indicated the diagnostic potential of the method with regard to the examination of the anatomy of the intracranial basal cisterns.
