Case 39: Progressive Glioma
摘要
The use of O-(2-[18F]fluoroethyl)-L-tyrosine ([18F]FET) PET permited a more sensitive assessment of metabolically active tumor, treatment failure, and distant non-contrast-enhancing progression in this patient with anaplastic oligodendroglioma, WHO grade III, where progression on MRI was challenged because of changing patterns of speckled new and dissolving old non-measurable contrast enhancement.
