目的比较低辐射剂量CT脑灌注成像与CT平扫在急性脑梗死诊断中的应用效果。方法选择2012年1月-2014年12月赵县人民医院收治的疑似急性脑梗死患者120例,分别采用CT平扫及低辐射剂量CT脑灌注成像扫描诊断,并对诊断结果进行对比分析。结果 120例疑似急性脑梗死患者进行CT平扫及低辐射剂量CT脑灌注成像扫描诊断结果发现,普通CT发现缺血灶的敏感性为25.00%(30/120),低辐射剂量CT脑灌注成像的敏感性达83.3%(100/120),差异有统计学意义(P<0.05)。结论大部分急性脑梗死患者可通过低辐射剂量CT脑灌注成像扫描作出诊断,诊断效果优于CT平扫,对指导临床治疗有着重要意义。
Objective To compare the effect of CT perfusion imaging with CT scan in the diagnosis of acute cerebral infarction. Methods A total of 120 patients with suspected acute cerebral infarction who were admitted to Zhao County People’s Hospital from January 2012 to December 2014 were selected for CT scan and CT scan respectively. The diagnostic results were compared and analyzed. Results 120 patients with suspected acute cerebral infarction CT scanning and low-dose CT cerebral perfusion imaging scan diagnostic results showed that common CT was found ischemic focal sensitivity was 25.00% (30/120), low-dose CT cerebral perfusion imaging The sensitivity was 83.3% (100/120), the difference was statistically significant (P <0.05). Conclusion Most patients with acute cerebral infarction can be diagnosed by low-dose CT cerebral perfusion imaging scan, the diagnostic effect is better than CT scan, which is of great significance to guide the clinical treatment.
