多层螺旋计算机断层扫描、磁共振成像对原发性颅脑肿瘤的诊断价值比较

Comparison of diagnostic value of multislice spiral computed tomography and magnetic resonance imaging in primary brain tumor

目的比较多层螺旋计算机断层扫描(MSCT)、磁共振成像(MRI)对原发性颅脑肿瘤的诊断价值。方法选取2017年10月至2020年12月本院诊治的60例疑似原发性颅脑肿瘤患者作为研究对象,均行MSCT、MRI检查。以手术病理结果为金标准,比较MSCT、MRI对原发性颅脑肿瘤的诊断效能;比较MSCT、MRI对不同病理类型原发性颅脑肿瘤的诊断准确度;分析不同病理类型原发性颅脑肿瘤的MSCT、MRI特征。结果手术病理结果显示,60例疑似原发性颅脑肿瘤患者中,阳性52例,阴性8例。MRI诊断原发性颅脑肿瘤的灵敏度、准确度、阴性预测值高于MSCT(P<0.05)。52例原发性颅脑肿瘤患者中,脑星形胶质瘤23例,脑膜瘤14例,室管膜肿瘤9例,髓母细胞瘤6例,MRI对脑星形胶质瘤的诊断准确度高于MSCT(P<0.05)。MSCT、MRI诊断原发性颅脑肿瘤诊断均可表现出典型性影像学特征。结论相较于MSCT,MRI诊断原发性颅脑肿瘤具有更高的灵敏度、准确度、阴性预测值,可及时明确不同类型原发性颅脑肿瘤的影像学特征,为后续治疗提供更为良好的参考依据。

Objective To compare the diagnostic value of multislice spiral computed tomography(MSCT)and magnetic resonance imaging(MRI)in primary brain tumor.Methods A total of 60 patients with suspected primary brain tumor diagnosed and treated in our hospital from October 2017 to December 2020 were selected as the research objects,all of them underwent MSCT and MRI examinations.Taking the surgical and pathological results as the gold standard,the diagnostic efficacy of MSCT and MRI in primary brain tumor was compared;the diagnostic accuracy of MSCT and MRI in different pathological types of primary brain tumor was compared;and the MSCT and MRI features of primary brain tumor with different pathological types were analyzed.Results The surgical and pathological results results showed that among 60patients with suspected primary brain tumor,52 cases were positive and 8 cases were negative.The sensitivity,accuracy and negative predictive value of MRI in the diagnosis of primary brain tumor were higher than those of MSCT(P<0.05).In52 patients with primary brain tumor,there were 23 cases of brain astrocytoma,14 cases of meningioma,9 cases of ependymal tumor and 6 cases of medulloblastoma,and the accuracy of MRI in the diagnosis of brain astrocytoma was higher than that of MSCT(P<0.05).MSCT and MRI in the diagnosis of primary brain tumor could show typical imaging characteristics.Conclusion Compared with MSCT,MRI in the diagnosis of primary brain tumor has higher sensitivity,accuracy and negative predictive value,which can timely identify the imaging features of primary brain tumor with different pathological types and provide a better reference for follow-up treatment.
