目的分析全脑灌注成像联合多层螺旋CT血管成像(CTA)诊断超早期脑梗死的临床意义。方法选取120例超早期脑梗死疑似患者作为研究对象,均于临床症状出现后6h内进行CTA、全脑灌注成像以及脑部CT检查,1周后进行常规多层螺旋CT复查。结果 CT扫描示32例为疑似脑缺血病变;所有患者全脑灌注成像显示,与患者临床表现相关的脑缺血部位均出现程度各异的梗死灶,脑组织血流量减少;CTA检查示,大脑中动脉闭塞18例,大脑中动脉狭窄12例,基底动脉狭窄4例,颈内动脉狭窄8例。结论全脑灌注成像联合CTA可为超早期脑梗死的临床诊断提供依据。
Objective To analyze the clinical significance of whole brain perfusion imaging combined with multi-slice spiral CT angiography (CTA) in the diagnosis of ultra-early cerebral infarction. Methods A total of 120 suspected patients with early-stage cerebral infarction were selected as subjects. CTA, whole-brain perfusion imaging and brain CT examination were performed within 6 hours after the onset of clinical symptoms. One week later, routine multi-slice spiral CT was performed. Results CT scan showed 32 cases of suspected ischemic lesions; all patients with whole brain perfusion imaging showed that all of the patients with clinical manifestations of cerebral ischemia showed varying degrees of infarction, brain blood flow decreased; CTA examination showed that, Middle cerebral artery occlusion in 18 cases, cerebral artery stenosis in 12 cases, 4 cases of basilar artery stenosis, carotid artery stenosis in 8 cases. Conclusion Whole brain perfusion imaging combined with CTA can provide the basis for the clinical diagnosis of ultra-early cerebral infarction.
