摘要
目的 探究磁共振成像(magnetic resonance imaging,MRI)与扩散加权成像(diffusion weighted imaging,DWI)对脑神经胶质瘤的诊断价值.方法 选取2021年4月—2023年3月聊城市人民医院收治的120例疑似脑神经胶质瘤患者为研究对象,全部患者均予以常规MRI平扫、MRI-DWI检查,以病理结果为金标准,分析MRI-DWI的诊断价值.结果 病理检出阳性96例,阴性24例.MRI检出阳性82例,MRI-DWI检出阳性92例.MRI-DWI的灵敏度[93.75%(90/96)]、特异度[91.66%(22/24)]及准确度[93.33%(112/120)]均高于MRI[78.12%(75/96)、70.83%(17/24)、76.66%(92/120)],差异有统计学意义(χ2=10.106、14.237、10.895,P均<0.05).结论 MRI-DWI在脑神经胶质瘤诊断中有着较高的诊断效能.
Abstract
Objective To explore the diagnostic value of magnetic resonance imaging(MRI)and diffusion-weighted imaging(DWI)for cerebral glioma.Methods A total of 120 suspected cerebral glioma patients admit-ted to Liaocheng People's Hospital from April 2021 to March 2023 were selected as the study objects.All pa-tients were examined by routine MRI plain scan and MRI-DWI,and the diagnostic value of MRI-DWI was ana-lyzed with pathological results as the gold standard.Results Pathological results showed 96 positive cases and 24 negative cases.MRI was positive in 82 cases and MRI-DWI was positive in 92 cases.The sensitivity[93.75%(90/96)],specificity[91.66%(22/24)]and accuracy[93.33%(112/120)]of MRI-DWI were signifi-cantly higher than those of MRI[78.12%(75/96)、70.83%(17/24)、76.67%(92/120)],and the differences were statistically significant(χ2=10.106,14.237,10.895,all P<0.05).Conclusion MRI-DWI has a high diagnostic efficacy in the diagnosis of cerebral glioma.
