摘要 目的 研究血管壁成像技术在急性脑梗死进展过程中的应用价值。方法 回顾2019年5月~2021年5月于本院就诊的97例急性脑梗死患者病例,所有患者均接受弥散加权成像(DWI)、高分辨率磁共振血管壁成像(HRMR-VWI)检查,以数字减影血管造影结果 作为“金标准”,对比DWI、HRMR-VWI诊断急性脑梗死的准确性,分析H RM R-VWI检测结果 中斑块负荷指数、管腔重构指数与颅内血管壁狭窄情况、临床分期进展情况以及梗死类型变化情况的相关性。结果 DSA结果 显示,97例患者中共有84例患者确诊存在血管狭窄或闭塞,HRM R-VWI诊断急性脑梗死的准确性高于DWI(P <0.05);闭塞及重度狭窄血管患者斑块负荷指数、管腔重构指数高于中度狭窄、轻度狭窄血管患者(P<0.05);亚急性期患者斑块负荷指数、管腔重构指数高于急性期、超早期患者(P<0.05);大面积脑梗死患者斑块负荷指数、管腔重构指数高于小面积脑梗死、腔隙性脑梗死患者(P<0.05)。结论 血管壁成像技术对急性脑梗死具有较高诊断效能,可体现病灶区域血管管腔重构和斑块强化情况,与颅内血管壁狹窄程度、临床分期进展、梗死类型变化均相关。 Objective To study the application value of vessel wall imaging technology in the progression of acute cerebral infarction.Methods A total of 97 patients with acute cerebral infarction treated in the hospital were enrolled between May 2019 and May 2021.All underwent diffusion-weighted imaging(DWI)and high-resolution magnetic resonance vessel wall imaging(HRMR-VWI)examinations.Taking the results of digital subtraction angiography(DSA)as golden standard,accuracy of DWI and HRMR-VWI in the diagnosis of acute cerebral infarction was compared.The correlation between plaque load index,lumen remodeling index and intracranial vessel wall stenosis,clinical staging,changes of infarction types was analyzed.Results DSA results showed that in the 97 patients,there were 84 cases confirmed with vascular stenosis or occlusion.The accuracy of HRMR-VWI in the diagnosis of acute cerebral infarction was higher than that of DWI(P<0.05).The plaque load index and lumen remodeling index in patients with occlusion and severe vascular stenosis were higher than those with moderate and mild stenosis(P<0.05).which were higher in patients during subacute stage than acute and ultra-early stages(P<0.05).The plaque load index and lumen remodeling index in patients with massive cerebral infarction were higher than those with small-area cerebral infarction and lacunar infarction(P<0.05).Conclusion The vessel wall imaging technique is of high diagnostic efficiency for acute cerebral infarction.It can reflect vascular lumen remodeling and plaque enhancement in focal area,which is related to the severity of intracranial vessel wall stenosis,progression of clinical staging and changes of infarction types.
