[摘要]目的 对CT 脑灌注成像技术诊断急性脑梗死的价值进行探讨。方法 选择该院于2014年1月—2014年8月期间收治的急性脑梗死患者60例作为研究对象,该组患者均在1周内经CT平扫并复查确诊为脑梗死;患者入院后均在6 h内进行接受16 层螺旋CT脑灌注成像,比较分析健侧正常区、半暗带区及脑梗死区的影像。结果 通过统计、计算CT脑灌注成像数据可知,在 CBF、CBV及MTT的平均值方面,脑梗死区与健侧区相比,差异有统计学意义(P<0.05);脑梗死区域、半暗带区及健侧区的CBV和MTT平均值呈逐渐下降趋势,而CBF成上升趋势。结论 急性脑梗死可利用16层螺旋 CT进行诊断,早期诊断效果良好,可为治疗提高准确的影像依据。

[Abstract] Objective To discuss the value of CT cerebral perfusion imaging technique in the diagnosis of acute cerebral infarction. Methods 60 patients with the acute cerebral infarction in our hospital in 2014 January to 2014 August as the research subjects, the groups of patients within 1 weeks after CT scan patients diagnosed as cerebral infarction; all the patients were performed within 6h received 16 slice spiral CT cerebral perfusion imaging, analysis and comparison of the contralateral normal region penumbra of cerebral infarction, and the image of the area. Results By statistics, calculating the CT cerebral perfusion imaging data shows that, in the average value of CBF, CBV and MTT, cerebral infarction area compared with the contralateral region, the difference was statistically(P<0.05); average value of cerebral infarction area, penumbra and contralateral regions of CBV and MTT decreased gradually, and CBF increased trend. Conclusion Acute cerebral infarction diagnosis can be carried out using 16 slice spiral CT, early diagnosis and good effect, can improve the imaging basis for proper treatment.

脑梗死是致死率较高的心脑血管疾病,是威胁我国老年群体身体健康的重要疾病。近年来,我国急性脑梗死发病率较高,该类患者死亡率和致残率,预后效果不够理想。对于急性脑梗死的临床治疗而言,早发现、早治疗可有效提高预后效果。CT 脑灌注成像是当前一种较为有效的脑梗死诊断手段,为此,该研究选择该院于2014年1月—2014年8月期间收治的急性脑梗死患者60例作为研究对象,对CT 脑灌注成像技术诊断急性脑梗死的价值进行了探讨,现报道如下。

1 资料与方法

1.1 一般资料

随机选择该院于2014年1月—2014年8月期间收治的急性脑梗死患者60例作为研究对象,该组患者均在1周内经CT平扫患复查确诊为脑梗死。入选患者中,男37例,女23例,年龄 47~69岁,平均年龄(59.4±15.1) 岁,发病时间约1.5~5.1 h。该组患者入院后,均出现不同程度的一侧肢体感觉麻木、抽搐、偏瘫、大小便失禁、失语等脑梗死症状,已排除其它疾病(颅内肿瘤、感染及陈旧性病灶等)的干扰[1]。……
