Artifacts originated from imaging hardware or instrumentation may be, on some occasions, confusing and peculiar to both physicians and technicians. Various artifacts from a variety of sources have been reported. In this note, we intend to describe a new one with an interesting pattern in whole-body scanning, which is strikingly different from its pattern in static spot view, in a patient presented for post-therapeutic 131I survey after total thyroidectomy.

Keywords: Post-therapeutic 131I survey, “Picture-in-Picture” artifact, whole-body scanning


Informed Consent: Written Informed consent was obtained from the patient before performing the scanning.

Peer-review: Externally peer-reviewed.
