Name the artefact and what it cost

When artefact limits a study, report which structure was lost and which test would recover it — in the impression.

'Limited by streak artefact from dental amalgam' tells the referrer that you saw a problem. It does not tell them what to do. The report that changes management says which structure was not assessable and what would assess it.

Compare: 'Beam-hardening from dental restorations degrades the floor of mouth; the left sublingual space cannot be excluded as involved. Consider MRI, or repeat CT on the photon-counting scanner if available.' That version gives the clinic a next step and puts the decision where the information is.

The same applies to a non-diagnostic study for any reason — respiratory motion, poor bolus timing, an uncooperative patient. Say which question remains unanswered, and name the test that would answer it.

  • Name the specific structure obscured, not just the artefact.
  • State the clinical question that remains unanswered.
  • Recommend the specific next test, including the scanner or sequence where it matters.
  • Say when the repeat should happen if timing affects the answer.
  • Keep the recommendation in the impression, where referrers read.

Why it matters

A limitation without a next step passes the problem back to the person least able to solve it.
