摘　　要：目的探讨不同级别胶质瘤与MRI图像纹理参数间相关性及纹理分析对术后预后的指导价值。方法选取107例胶质瘤患者,记录MRI图像各纹理参数。分析胶质瘤分级与MRI图像各纹理参数之间的相关性。分析影响胶质瘤患者术后不良的危险因素,评估各纹理参数预测胶质瘤分级和术后良好情况的诊断效能。结果低级别胶质瘤患者和高级别胶质瘤患者的MRI图像纹理参数比较,峰度、偏度、标准差、对比度、均匀度无显著差异,相关度、熵值、一致性、逆差距有显著差异。相关度、熵值、一致性、逆差距与胶质瘤分级有明显相关性。熵值预测胶质瘤分级诊断效能明显高于相关度、一致性、逆差距。四者联合预测胶质瘤患者术后良好的诊断效能最高。结论MRI图像纹理参数中的相关度、熵值、一致性、逆差距能有效诊断胶质瘤分级程度,四者联合使用更有利于胶质瘤患者的术后评估。Objective To investigate the correlation between different grade glioma and MRI image texture parameters and the guiding value of texture analysis for postoperative prognosis.Methods A total of 107 glioma patients were selected,and the texture parameters of MRI images were recorded.The correlation between the grade of glioma and the texture parameters of MRI images was analyzed.The risk factors affecting postoperative adverse effects of glioma patients were analyzed,and the diagnostic efficacy of each texture parameter in predicting glioma grade and postoperative good condition was evaluated.Results Comparison of MRI image texture parameters between patients with low-grade glioma and patients with high-grade glioma showed no significant differences in kurtosis,skewness,standard deviation,contrast and uniformity,but significant differences in correlation,entropy,consistency and gap distance.Correlation,entropy,consistency and gap distance were significantly correlated with glioma grade.The diagostic efficiency of entropy in predicting glioma grade was significantly higher than that of correlation,consistency and gap distance.The combination of the four predicted glioma patients with good postoperative diagnostic efficacy was the highest.Conclusion The correlation,entropy,consistency and gap distance of MRI image texture parameters can effectively diagnose the grade of glioma,and the combination of the four parameters is more beneficial to the postoperative evaluation of glioma patients.
