In this Through the Lens case, Dr. Jamie Elifritz identifies an artifact demonstrated on PMCT and explains its significance in postmortem imaging. (Or is it artefact?)
Case 2025.06
Case: What artifact is demonstrated in this case?
Learning Point
ANSWER: Ring Artifact
Ring Artifact: Secondary to miscalibration or (most commonly) failure of detector elements. This typically occurs close to the isocentre of the scan and is usually visible on multiple slices at the same location. When related to the detector, you need to recalibrate or replace the detector. Artifact can degrade diagnostic accuracy.
