The Manifestation of a Patient With Myelofibrosis in 68Ga-DOTA-FAPI-04 PET/CT Mimicking "Super Bone Imaging".

ABSTRACT: Primary myelofibrosis is a chronic inflammatory disease of the bone marrow. It progresses from an early robust inflammatory state to a more advanced fibrotic response, representing the advanced stage of the disease. We report a 50-year-old woman who was diagnosed with primary myelofibrosis. 18F-FDG PET/CT showed mild uptake in diffuse sclerotic lesions in the bone matrix, whereas 68Ga-DOTA-FAPI-04 showed intense uptake at the whole skeleton.
