Identification of prognostically relevant residual tumor in glioblastoma after surgery: A comparative analysis of MR-based RANO resect classes vs. [18F]FET PET.
BACKGROUND Assessment of postoperative tumor burden is essential in IDH-wildtype glioblastoma. The RANO resect classification stratifies patients based on residual tumor volume on postoperative MRI. [¹⁸F]FET PET can detect metabolically active tumor-suspicious tissue invisible on MRI. Its additional prognostic contribu...
