脑内肿瘤诊断中核磁共振波谱的应用价值分析

目的:探究核磁共振波谱在脑内肿瘤诊断中的应用价值。方法:选取某院2016年3月~2018年3月期间收治的74例疑似为脑内肿瘤患者作为对象,分别予以正电子发射型计算机断层显像(PET)-CT诊断及核磁共振波谱诊断,以患者的病理学诊断结果作为"金标准",比较不同检查方法的准确率、敏感度及特意度。结果:经过病理学诊断74例疑似脑内肿瘤患者确诊共52例,占比例为70.27%,应用PET诊断的准确率63.46%低于应用核磁共振波谱诊断准确率96.15%,有统计学差异性(χ~2=17.244,P<0.05);应用核磁共振波谱诊断的敏感度59.62%、特异度86.36%均高于PET诊断38.46%、59.09%,有统计学差异(P<0.05)。结论:脑内肿瘤诊断中应用核磁共振波谱,准确率高,敏感性、特异性好,可以广泛应用。

Application Value of Magnetic Resonance Spectroscopy in the Diagnosis of Brain Tumors

Objective:To explore the value of magnetic resonance spectroscopy in the diagnosis of brain tumors.Methods:74 patients with suspected intracerebral tumors admitted to a hospital from March 2016 to March 2018 were selected as subjects.Positron emission computed tomography(PET)and magnetic resonance spectroscopy(NMR)were respectively used to diagnose the brain tumors.Pathological diagnosis results of the patients were used as"gold standard"to compare the accuracy,sensitivity and specificity of different methods.Results:The diagnostic accuracy of PET was 63.46%,lower than that of NMR(96.15%),with statistical differences(χ^2=17.244,P<0.05).The sensitivity and specificity of NMR were 59.62%and 86.36%,higher than that of PET 38.46%and 59.09%(P<0.05).Conclusion:Nuclear magnetic resonance spectroscopy(NMR)can be widely used in the diagnosis of brain tumors because of its high accuracy,good sensitivity and specificity.
