目的: 探讨螺旋CT头颈部CT血管造影(CT angiography,CTA)检查诊断脑梗死的价值与优势。方法: 2015年2月至2017年2月选择脑梗死患者160例作为研究对象,所有患者都进行头颈部CTA检查,记录诊断效果。结果: 160例患者的患侧脑血流量(CBF)、达峰时间(TTP)、脑血容量(CBV)和平均通过时间(MTT)分别为(24.38±6.42)mL/(100 g·min)、(3.58±1.23)mL/100g、(8.11±2.67)s、(23.19±5.99)s,与健侧对比,差异有统计学意义(P＜0.05)。160例患者CTA都检出颈动脉斑块,其中软斑块40例、混合斑块60例、硬斑块60例。结论: 螺旋CT头颈部CTA检查诊断脑梗死有很好的应用价值,能反映疾病程度与斑块性质,值得推广应用。
Objective: To discuss the value and advantage of head and neck CT angiography (CTA) examination by spiral CT in the diagnosis of cerebral infarction.Methods: 160 cases of patients with cerebral infarction from February 2015 to February 2017 treated in the hospital were selected as the research objects. All patients were given head and neck CTA examination by spiral CT and the diagnostic effects were recorded.Results: The CBF, TTP, CBV and MTT values in the injured side were (24.38±6.42)mL/(100g·min), (3.58±1.23)mL/100g, (8.11±2.67)s and (23.19±5.99)s respectively, which had significant difference from those in the healthy side (P＜0.05). Carotid plaques were detected in the 160 patients with CTA examination, including 40 cases of soft plaque, 60 cases of mixed plaque, and 60 cases of hard plaque.Conclusion: Head and neck CTA examination by spiral CT in the diagnosis of cerebral infarction has a good application value and can reflect the degree of disease and plaque nature. It is worthy of popularization and application.
