Coupling of Inflammation and Microcalcification in the Pathogenesis of Prostate Calculi: Detection Using 18 F-NaF and 18 F-FDG PET/CT

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.

Simultaneous Uptake of 18 F-NaF and 18 F-FDG by Bladder and Prostate Calculi

ABSTRACT

Calcification and formation of calculi in the genitourinary system such as the bladder, kidney, and prostate are common processes of aging. Despite being in different parts of the body, these calculi can share risk factors; for instance, bladder and prostate calculi are seen in older men with benign prostatic hyperplasia. There have been increasing reports of detection of calculi using PET tracers such as 18 F-NaF and 18 F-FDG, suggesting their role for detection of extraosseous calcification. In this report, we present simultaneous detection of bladder and prostate calculi with both 18 F-NaF and 18 F-FDG avidity in a 74-year-old man with multiple myeloma.
