目的分析磁共振弥散加权成像(DWI)在急性脑梗死中的应用价值。方法 120例急性脑梗死患者作为研究对象,所有患者均经CT扫描、常规核磁共振成像(MRI)扫描及DWI扫描,回顾性分析患者的临床资料,就其检测结果展开分析。结果经临床追踪随访及影像复查确诊,120例患者中,48例为超急性期脑梗死、60例为急性期脑梗死、12例为亚急性期脑梗死。120例患者中共检出病灶144个,其中新发病灶105个,合并慢性期梗死病灶39个。经CT扫描检出率为65.83%,MRI检出率为73.33%,DWI检出率99.17%,DWI检出率显著高于CT扫描和MRI检查,差异有统计学意义(P<0.05)。结论针对急性脑梗死患者可行磁共振DWI检查,能够准确的检出患者病灶情况,诊断患者疾病情况,值得临床推广。
Objective To analyze the value of magnetic resonance diffusion-weighted imaging (DWI) in acute cerebral infarction. Methods A total of 120 patients with acute cerebral infarction were enrolled in this study. All patients underwent CT scan, conventional magnetic resonance imaging (MRI) scan and DWI scan. The clinical data of the patients were retrospectively analyzed and their test results were analyzed. Results After clinical follow-up and imaging diagnosis, 48 out of 120 patients were hyperacute cerebral infarction, 60 were acute cerebral infarction and 12 were subacute cerebral infarction. Of the 120 patients, 144 were detected, of which 105 were new and 39 were associated with chronic infarction. The detection rate of CT scan was 65.83%, the detection rate of MRI was 73.33%, the detection rate of DWI was 99.17%. The detection rate of DWI was significantly higher than that of CT scan and MRI (P <0.05). Conclusions Acute cerebral infarction patients with feasible magnetic resonance imaging (DWI) examination can accurately detect the patient’s lesion and diagnose the patient’s disease, which is worthy of clinical promotion.
