【摘要】 目的分析血管成像(MRA)和磁共振弥散加权成像(DWI)联合应用在评估超急性脑梗死介入中的诊断价值。方法选择某院自2018年1月至2019年8月收治的29例行介入诊断的超急性脑梗死患者作为研究对象,治疗前,分别对患者行常规MRI检查及MRA联合DWI检查,对比两种检查方法对病灶的阳性检出率,并对比患者介入诊断前后梗死灶中央区ADC值、rADC值。结果 MRA联合DWI对病灶的阳性检出率(100.00%)显著高于MRI(51.72%),两组对比具有统计学意义(P<0.05),且MRA联合DWI诊断显示,超急性脑梗死病灶主要分布在额颞顶叶,14例患者病灶均位于额颞顶叶,6例患者病灶位于额颞叶,4例患者病灶位于颞枕叶、3例患者病灶位于额顶叶、2例患者病灶位于基底节室旁。治疗后,患者梗死灶中央区ADC值(1.05±0.37)×10~4mm~2/s、rADC值(20.11±2.18)%均显著低于治疗前(3.92±1.14)×10~4mm~2/s、(45.26±3.47)%,前后对比具有统计学意义(P<0.05)。结论 MRA和DWI联合应用在评估超急性脑梗死介入治疗效果的诊断价值显著,值得推广。更多还原

【Abstract】 Objective To analyze the diagnostic value of vascular imaging MRA combined with diffusion-weighted magnetic resonance imaging DWI in evaluating the intervention of hyperacute cerebral infarction.Methods We selected 29 patients with ultra-acute cerebral infarction treated in our hospital from January 2018 to August 2019 as the subjects. Before treatment, routine MRI and MRA combined with DWI examination were performed to compare the positive detection rate of the two methods on the lesions, and compared the ADC value and rADC value of infarction after intervention. Results The positive rate of MRA combined with DWI(100.00%) was significantly higher than that of MRI(51.72%). The diagnosis of hyperacute cerebral infarction(MRA) combined with DWI showed that hyperacute cerebral infarction was mainly located in frontotemporal parietal lobe, 14 cases were located in frontotemporal parietal lobe, 6 cases were located in frontotemporal lobe, 4 cases were located in temporal occipital lobe, 3 cases were located in frontotemporal lobe. The lesions were located in the basal ganglia of 2 patients. After treatment, the ADC value of the central area of the infarction was(1.05±0.37)×10~4mm~2/s, The rADC value(20.11±2.18)% was significantly lower than that before treatment(3.92±1.14)×10~4mm~2/s,(45.26±3.47)%. There was significant difference between before and after treatment(P<0.05). Conclusion The combined value of MRA and DWI in the evaluation of the interventional effect of hyperacute cerebral infarction is significant and worthy of promotion.更多还原
