Fig. 4From: Differentiation of Pseudoprogression from True Progressionin Glioblastoma Patients after Standard Treatment: A Machine Learning Strategy Combinedwith Radiomics Features from T1-weighted Contrast-enhanced ImagingT1CE images showing true progression in a 48-year-old male patient with GBM. (a) Postoperative MRI (within 24Â h after surgery) showed that the tumor was completely resected. (b) Two months after CCRT, the new enhancement disappeared. After CCRT and at the (c) 6-and (d) 9-month follow-ups, the follow-up MR images demonstrated that the extension of the enhanced lesion increased. Recurrence was confirmed by second surgical pathology. (GBM: glioblastoma multiforme)Back to article page
