“Picture-in-Picture” Artifact in Post-therapeutic 131 I Whole-body Survey: Deceiving Spot View but Unraveling Whole-body Scanning

[摘要] 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 131 I survey after total thyroidectomy.
