Halo artifacts of indwelling urinary catheter by inaccurate scatter correction in (18)F-FDG PET/CT imaging: incidence, mechanism, and solutions

BACKGROUND: Halo artifacts from urinary catheters can occur due to inaccurate scatter correction, and the artifacts affect the tumor visibility in (18)F-FDG PET/CT images. We investigated the incidence rate and the mechanisms of halo-artifact generation and explored several scatter correction techni...
