探讨3.0T磁共振3D-ASL与MRA成像在缺血缺氧性脑病的运用

To Explore the Application of 3.0T Magnetic Resonance 3D-ASL and MRA Imaging in Ischemic and Hypoxic Encephalopathy

摘要: 目的：旨在探讨磁共振3D-ASL脑灌注技术与MRA血管成像技术对缺血缺氧性脑病患者的诊断价值。方法：回顾性分析2019年10月~2020年10月期间在本院收治的60例疑似缺血缺氧性脑病患者的临床资料，以数字化血管造影诊断技术(DSA)和临床诊断作为诊断的金标准，所有患者均进行3.0T磁共振3D-ASL技术检查与磁共振MRA检查，对比两组诊断效果。结果：3.0T磁共振3D-ASL灌注技术的诊断符合率高于磁共振MRA诊断率，误诊率与漏诊率均低于磁共振MRA诊断，两者综合诊断符合率明显高于单个检查技术，表明研究有统计学意义(P < 0.05)。结论：缺血缺氧性脑病患者使用3.0T磁共振3D-ASL脑灌注技术和MRA成像进行综合诊断，具有更高的诊断准确性，为临床治疗缺血缺氧性脑病患者提供可靠诊断依据。

Abstract: Objective: To investigate the diagnostic value of MR 3D-ASL cerebral perfusion technique and MRA vascular imaging technique in patients with ischemic hypoxic encephalopathy. Methods: The clin-ical data of 60 patients with suspected hypoxic ischemic encephalopathy admitted to our hospital from October 2019 to October 2020 were retrospectively analyzed. Digital angiography diagnostic technique (DSA) and clinical diagnosis were used as the gold standard for diagnosis. All patients underwent 3.0T MR 3D-ASL examination and magnetic resonance MRA examination, and the di-agnostic effects of the two groups were compared. Results: The diagnostic coincidence rate of 3D-ASL perfusion technique was higher than that of MRA, and the misdiagnosis rate and missed rate were lower than those of MRA diagnosis. The comprehensive coincidence rate of both was significantly higher than that of single examination technique, indicating that the study had statis-tical significance (P < 0.05). Conclusion: 3.0T magnetic resonance 3D-ASL brain perfusion technol-ogy and MRA imaging provide reliable diagnostic accuracy for clinical treatment of ischemic hypoxic encephalopathy patients.
