Synopsis
Edema in GB is characterized by the presence of tumor cells infiltration as compared to brain metastasis with only pure edema. Radiomics features extracted using FLAIR images in GB and BM are found to be exhibiting variation in some of the entropy and non-uniformity-based features, which could be used as signature to differentiate GB from brain metastasis.
