Fig. 2From: Effects of furosemide and tracer selection on urinary activity and peri-bladder artefacts in PSMA PET/CT: a single-centre retrospective studyPSMA PET/CT with 18F-DCFPyL used as tracer in a 68 years old man staged for staging of biochemical recurrence of prostate cancer showing peri-bladder artefacts, deteriorating image quality and impairing image interpretation. A Axial PET reconstructions; B fused axial PET/CT reconstructions; and C PET maximum intensity projection (MIP). Window width SUV range 0–7 applied. Red arrows: PET photopenic area (halo artefact). Green arrows: increased PET activity (flare artefact).Back to article page
