摘要
目的分析老年出血性脑梗死的疾病特点,评价行电子计算机断层扫描(CT)、磁共振成像(MRI)进行临床诊断的价值。方法80例老年出血性脑梗死患者,均经数字减影血管造影(DSA)确诊,均行CT、MRI检查。以DSA检查结果作为诊断金标准,对比两种检查方法的诊断准确率。分析两种检查方法的影像学表现。结果80例患者经DSA检查后确诊急性期23例、亚急性期40例、慢性期17例。MRI检查的诊断准确率98.75%高于CT的87.50%,差异具有统计学意义(P<0.05)。CT检查显示有大片扇形低密度阴影,且阴影中有散点状、条索状高密度影等表现;MRI检查显示脑梗死区域有混杂斑块状信号等表现。结论老年出血性脑梗死的发病率较高,需积极诊断、治疗。MRI检查具有更高的诊断效能,有助于临床早期治疗工作的开展,提升患者治疗预后。
Objective To analyze the characteristics of hemorrhagic cerebral infarction and the status of the elderly patients,and to evaluate the clinical diagnostic value of computed tomography(CT)and magnetic resonance imaging(MRI).Methods 80 elderly patients with hemorrhagic cerebral infarction were diagnosed by digital subtraction angiography(DSA),and examined with CT and MRI.The results of DSA were taken as the gold standard for diagnosis,and the diagnostic accuracy of these two methods was compared.The imaging findings of these two methods were analyzed.Results After 80 patients were examined by DSA,23 patients were in the acute phase,40 patients were in the subacute phase and 17 patients were in the chronic phase.The diagnostic accuracy of MRI examination was 98.75%,which was higher than 87.50%of CT examination,and the difference was statistically significant(P<0.05).CT examination showed fan-shaped low-density shadows,with scattered spots and strip-shaped high-density shadows in the shadows.MRI examination showed mixed plaque signals and the like in the cerebral infarction area.Conclusion The incidence of hemorrhagic cerebral infarction in elderly patients is high,requiring active diagnosis and treatment.MRI examination has relatively high diagnostic efficiency,which is helpful for early clinical treatment and improves the prognosis of patients.
