Whole muscle 18F-choline uptake due to intense physical exercise

Abstract

We report an 18F-choline PET/CT scan performed on a 74-year-old patient with history of prostate neoplasm in the clinical context of progressive PSA elevation (10ng/ml) with negative imaging tests. Pelvic images were acquired at 5 min. post-injection of standardized radiotracer dose, while whole-body images were obtained 45 and 120 min. after injection (Figure-1; MIP images). A homogeneous increased uptake of tracer in the whole axial and appendicular muscle structures was highlighted in all series. A SUVmax of 4.8, 5.0 and 4.9 were reached in a reference ROI at left gluteus maximus muscle (Figure-1; axial fused imaWhole muscle 18F-choline uptake due to intense physical exercise _______________________________________________
