In a retrospective study the CT scans of 138 patients with the clinical diagnosis of SAH were reviewed. CT was highly sensitive in detecting blood in the CSF spaces during the 3 days following SAH, with decreasing accuracy correlated to the time interval between SAH and CT examination. Clinical state on admission and CT findings were closely related, as were the localisation of detectable blood and the site of source of bleeding. Whereas blood clots in the basal cisterns, above the convexities, and intracerebrally, as well as the finding of a brain oedema, were significantly correlated to the time of survival, hydrocephalus and ventricular haemorrhage had no bearing on the survival time.
在一项回顾性研究中，对138例临床诊断为蛛网膜下腔出血（SAH）患者的CT扫描结果进行了复查。SAH后3天内，CT对检测脑脊液间隙内的血液高度敏感，其准确性随SAH与CT检查时间间隔的延长而降低。入院时的临床状态与CT表现密切相关，可检测到血液的部位与出血源部位也密切相关。基底池、脑凸面上方及脑内的血凝块以及脑水肿的发现与生存时间显著相关，而脑积水和脑室出血与生存时间无关。
