[摘要] 目的 探讨计算机体层摄影(CT)与磁共振成像(MRI)影像技术在早期诊断急性脑梗塞中的临床应用。方法 方便选取该院2015年12月—2017年2月收治的80例早期急性脑梗塞患者为研究对象,所有患者均采用CT、MRI 2种影像技术进行检查。比较2种方法的检出情况和不同时间段的诊断率情况。结果 MRI对腔隙性脑梗塞、缺血性脑梗塞诊断率分别为95.00%、86.84%,均明显高于CT(60.00%、42.11%,P<0.05);但对出血性脑梗塞诊断率与CT比较差异无统计学意义(P>0.05)。24 h内MRI的诊断率明显高于CT(P<0.05),但24 h后MRI的诊断率与CT相比差异无统计学意义(P>0.05)。结论 与CT相比,MRI早期诊断急性脑梗塞的诊断符合率更高,且在诊断不同类型急性脑梗塞上亦更具优势。

[Abstract] Objective To study the clinical application of CT and MRI in early diagnosis of acute cerebral infarction. Methods 80 cases of patients with early acute cerebral infraction admitted and treated in our hospital from December 2015 to February 2017 were convenient selected as the research objects and examined by the CT and MRI, and the test, and diagnosis rates at different time periods were compared. Results The diagnosis rates of MRI in lacunar infarction and ischemic brain infarction were obviously higher than those of CT(95.00%,86.84% vs 60.00%,42.11%),(P<0.05), but the difference in the diagnosis of hemorrhagic infarction between the two methods was not statistically significant(P>0.05), and the diagnosis rate of MRI in 24 h was obviously higher that of CT(P<0.05), but the difference in the diagnosis rate between the MRI and CT after 24 h was statistically significant(P>0.05). Conclusion The coincidence rate of MRI in early diagnosis of acute cerebral infarction is higher than that of CT, and the MRI is more advantageous in diagnosis of different types of acute cerebral infarction.

急性脑梗塞是一种常见脑血管疾病,主要是由于供应脑部血液的动脉出现粥样硬化和血栓形成,使血管腔狭窄甚至闭塞,导致脑血供突然中断后引发的脑组织坏死[1]。急性脑梗塞多发生于中老年人,起病快,一般2 d内达到高峰,具有很高的致残率和致死率,严重威胁患者的生命安全[2]。因此,早期诊断急性脑梗塞具有重要意义。目前影像学早期检查急性脑梗塞主要有计算机体层摄影(CT)和磁共振成像(MRI)。该研究方便选取该院2015年12月—2017年2月收治的80例早期急性脑梗塞患者为研究对象,探讨CT与MRI影像技术在早期诊断急性脑梗塞中的临床应用,现报道如下。
