A novel round artifact was observed on SPECT/CT images, characterized by a dark spot and light ring. Servicing the SPECT system resolved this previously unreported scanner-based artifact.

Area of Science:

  • Medical Imaging
  • Nuclear Medicine
  • Radiology

Background:

  • Hybrid imaging systems like SPECT/CT are crucial for accurate diagnosis.
  • Scanner-based artifacts can mimic pathology, leading to misdiagnosis.
  • Reporting novel artifacts is essential for quality control in medical imaging.

Purpose of the Study:

  • To describe a previously unreported round artifact encountered during SPECT/CT imaging.
  • To detail the characteristics and origin of this specific artifact.
  • To highlight the importance of system maintenance in preventing imaging artifacts.

Main Methods:

  • Acquisition of SPECT/CT images using a hybrid imaging system.
  • Identification and characterization of a distinct round artifact.
Keywords:

  • Troubleshooting and servicing of the SPECT component of the hybrid system.

    • Main Results:

    • A round artifact, appearing as a central dark spot with a surrounding light ring, was consistently observed.
    • The artifact was localized to the SPECT component of the SPECT/CT system.
    • Post-servicing, the artifact was completely eliminated from subsequent images.

    Conclusions:

    • A novel scanner-based artifact in SPECT/CT imaging has been identified and described.
    • This artifact is attributed to a malfunction within the SPECT system.
    • Regular maintenance and prompt servicing are vital for ensuring the integrity of SPECT/CT imaging data.
