چکیده انگلیسی
Twenty-two patients with pathologically confirmed glioblastoma who had received concurrent CCRT with TMZ underwent conventional MRI including T1-weighted imaging(T1WI), T2-weighted imaging(T2WI), fluid attenuated inversion recovery(FLAIR)and contrast-enhanced T1WI(T1Ce). Five GLCM texture maps of contrast, energy, entropy, correlation and homogeneity were generated for each MRI series. Of the aforementioned 5 texture features, the most significant features were contrast and correlation on T2WI with areas under ROC curve of 0.883 and 0.892, respectively, and they had the same sensitivity of 75%, specificity of 100%, accuracy of 86.4%, PPV of 100% and NPV of 76.9% in differentiation true progression from pseudoprogression.
