摘　　要：目的探讨磁敏感加权成像（SWI）在检测热射病患者颅内出血灶和评估预后上的价值。方法搜集8例Glasgow评分为3—9分的热射病患者发病后2～5天常规MRI和SWI检查资料，观察患者颅内有无出血灶，并分析其与预后的关系。结果8例中，常规MRI序列检查均未发现颅内出血病灶。SWI检查发现3例有斑点状出血灶，病灶分别位于脑干、放射冠和额叶。此3例患者中有2例分别于发病后第5天和第25天死亡，另l例成为植物人并于发病3个月后死亡；其他5例未检测到出血灶的热射病患者均慢慢恢复，仅有不同程度小脑共济失调症状。结论颅内出血与热射病患者病死率密切相关，SWI可敏感检测颅内出血灶，有助于评估热射病的预后。Objective To assess the role of susceptibility weighted imaging in the detection of intracranial hemorrhage after heart stroke and in the prognosis. Methods The study group consisted of eight patients after heart stroke, with a score of 3 to 9 in Glasgow Coma Scale. The MR studies including susceptibility weighted imaging data were collected within 2 -5 days after heart stroke. Results Punctate hemorrhages were detected in brain stem, corona radiata and frontal lobe by susceptibility weighted imaging for three patients. Among the three cases, two patients came to death in the 5th day and the 25th day after heart stroke respectively. Another patient became a persistent vegetative state and died about 3 months later. Five patients with no hemorrhage detected gradually recovered and cerebellar dysfunction remained to various de- grees. Conclusion Heart stroke is a life threatening condition characterized by hyperthermia and accompanied by various complications such as disseminated intravascular coagulation. Susceptibility weighted imaging is a very useful tool for detec- tion of intracranial hemorrhage and may probably evaluate the prognosis after heart stroke.
