DWI结合SWI对急性脑梗死患者脑微出血的诊断价值


【摘要】 目的:探讨弥散加权成像(diffusion weighted imaging,DWI)结合磁敏感加权成像(susceptibility weighted imaging,SWI)对急性脑梗死患者脑微出血的诊断价值。方法:研究纳入2021年1月—2024年1月淮安八十二医院收治的102例急性脑梗死患者。所有患者均行DWI、SWI检查,以病理诊断结果为金标准,比较DWI、SWI单独及联合检查在急性脑梗死患者脑微出血中的诊断价值。结果:102例患者中,有95例合并脑微出血。DWI诊断脑微出血有67例,SWI诊断脑微出血有78例,联合诊断脑微出血有87例。DWI、SWI联合诊断急性脑梗死患者脑微出血的准确度、敏感度、特异度、阳性预测值、阴性预测值分别为91.18%、91.58%、85.71%、98.86%、42.86%。联合诊断脑微出血的准确度均高于单项检测,敏感度和阴性预测值均高于DWI单独检测(Plt;0.05)。结论:联合使用DWI、SWI可提高诊断急性脑梗死患者脑微出血的敏感度和特异度。

Diagnostic Value of DWI Combined with SWI for Cerebral Microbleeds in Patients with Acute Cerebral Infarction/WAN Runji, ZHOU Pengcheng, LI Liang. //Medical Innovation of China, 2025, 22(04): -137
[Abstract] Objective: To explore the diagnostic value of diffusion weighted imaging (DWI) combined with susceptibility weighted imaging (SWI) for cerebral microbleeds in patients with acute cerebral infarction. Method: The study included 102 patients with acute cerebral infarction admitted to Huai’an No. 82 Hospital from January 2021 to January 2024. All patients underwent DWI and SWI examination. Taking pathological diagnosis results as the gold standard ......
