目的：探讨磁敏感加权成像在出血性脑梗死中的诊断价值。方法以我院放射科收治的25例缺血性脑卒中患者为研究对象，根据其临床资料进行回顾性分析，分别对其进行常规MRI、扩散加权成像以及磁敏感加权成像检查，根据图像分析结果比较不同扫描序列检出梗死灶内出血灶的情况。结果25例患者发现47个出血灶，其中SWI序列显示出血灶46个，T1WI序列显示出血灶27个，DWI序列显示出血灶16个，T2WI显示出血灶11个，SWI序列对出血灶的检出率明显高于T1WI、T1W2、DWI，p＜0.05，差异有统计学意义；SWI序列发现14例患者存在微出血灶的情况。结论磁敏感加权成像用于临床诊断出血性脑梗死，其影像具有一定的特征性，对病灶内出血情况的显示优于常规MRI和DWI序列，可以了解梗死灶内静脉血管的变化和微小出血灶的情况，能为患者临床治疗提供重要的参考依据，具有较高的临床使用价值。

Objective To explore diagnostic value of magnetic sensitive weighted imaging in hemorrhagic cerebral infarction. Methods Twenty five patients with ischemic cerebral apoplexy admitted in the Radiology Department of the Hospital were selected as research subjects,retrospective analysis was made according to their clinical data,the patients underwent conventional magnetic resonance imaging(MRI),weighted diffusion imaging and magnetic sensitive weighted imaging,and internal infarct hemorrhage lesions detected via different scanning sequences were compared according to results of image analysis. Results Forty seven hemorrhage lesions were found in 25 patients,SWI sequence had 46 hemorrhage lesions shown,T1WI sequences displayed 27 hemorrhage lesions,DWI sequence displayed 16 hemorrhage lesions,and T1W2 displayed 11 hemorrhage lesions. The positive rate of SWI sequence on hemorrhage lesions was much higher than that of T1WI,T1W2 or DWI(p<0.05),and the differences were significant.Fourteen patients were found to suffer from micro hemorrhage conditions. Conclusion The image of magnetic sensitive weighted imaging used in clinical diagnosis of hemorrhagic cerebral infarction casts certain characteristics,the display of magnetic sensitive weighted imaging on focal hemorrhage conditions were better than conventional MRI and DWI sequence,changed in veins in infarcts and conditions of tiny hemorrhage lesions may be got by this technique, which can offer important reference basis for clinical treatment,delivering high value of clinical use.
