分析CT、MRI检查对高级别脑胶质瘤的诊断价值

摘要/Abstract

摘要： 目的分析CT、MRI检查对高级别脑胶质瘤的诊断价值。方法选取2018年1月—2023年1月通辽市科尔沁区第一人民医院收治的80例疑似脑胶质瘤患者作为研究对象,分别进行CT及MRI检查,总结脑胶质瘤在CT及MRI检查中的影像学表现特征,以病理检查结果为金标准,分析CT、MRI单独检查及联合检查对高级别脑胶质瘤的诊断价值。结果 CT检查以低密度病变最为常见,增强CT扫描以花环状强化最为常见。MRI检查以T2WI高信号、T1WI低信号最为常见,增强MRI扫描主要表现为边缘强化及结节强化。CT、MRI及CT、MRI联合检查诊断脑胶质瘤的灵敏度分别为76.92%、90.38%、96.15%,特异度分别为75.00%、85.71%、96.43%,准确度分别为76.25%、88.75%、96.25%,阳性预测值分别为85.11%、92.16%、98.04%,阴性预测值分别为63.64%、82.76%、93.10%,联合检测灵敏度、特异度、准确度、阳性预测值、阴性预测值均大于CT单独检测（P<0.05）。ROC曲线分析结果显示,CT、MRI及联合检查AUC值分别为0.724、0.755、0.802,对于脑胶质瘤均具有一定诊断价值。结论 CT联合MRI对高级别脑胶质瘤具有较高的诊断价值,可显示病灶的范围和图像特征,为临床高级别脑胶质瘤的诊断提供影像学依据。

Abstract: Objective To analyze the diagnostic value of CT and MRI in gliomas. Methods Eighty patients with suspected glioma admitted to Tongliao City Keerqin District First People's Hospital from January 2018 to January 2023 were selected as the research objects. CT and MRI examinations were performed respectively to summarize the imaging features of glioma in CT and MRI examinations. Pathological examination results were taken as the gold standard to analyze the diagnostic value of CT and MRI alone and combined examination for glioma. Results Low density lesions were the most common CT scan, and floral ring enhancement was the most common enhanced CT scan. High signal on T2WI and low signal on T1WI were the most common manifestations of MRI. Enhanced MRI mainly showed edge enhancement and nodule enhancement. The sensitivity, specificity and accuracy of CT, MRI and combined CT and MRI in the diagnosis of glioma were 76.92%, 90.38% and 96.15%, 75.00%, 85.71% and 96.43%, and 76.25%, 88.75% and 96.25%, respectively. The positive predictive values were 85.11%, 92.16%, 98.04%, and the negative predictive values were 63.64%, 82.76%, 93.10%, respectively. The above indexes were higher than those detected by CT alone (P<0.05). ROC curve analysis showed that CT, MRI and combined examination had certain diagnostic value for glioma. Conclusion CT combined with MRI has high diagnostic value for gliomas, which can display the range and image features of the lesion and provide imaging basis for the clinical diagnosis and treatment of gliomas.
