Abstract:
We encountered a round artifact on images obtained with our SPECT/CT system: a small dark spot surrounded by a broad light ring. The artifact was due to a problem with the SPECT portion of the hybrid system and was successfully removed through servicing of the system. This case report describes this scanner-based artifact, which, to our knowledge, has not previously been reported in the literature.
