Imaging of Rotator Cuff Calcific Tendinopathy Using 18 F-NaF and 18 F-FDG PET/CT.

ABSTRACT:Calcific tendinopathy is a common condition of the shoulder caused by the inflammation and deposition of hydroxyapatite crystals in the rotator cuff tendons. PET tracers capturing the molecular changes associated with the crystal deposition of calcific tendinopathy remain underinvestigated. In this report, we present calcified tendinopathy of the infraspinatus tendon demonstrating both 18 F-NaF and 18 F-FDG focal uptake in a 61-year-old woman.
