If motion artifacts limit evaluation on a CT study, how should the report address this limitation?

If motion artifacts limit evaluation on a CT study, how should the report address this limitation?

• A. If motion artifacts limit evaluation, state the limitations and suggest clinical correlation or alternative imaging if warranted.
• B. If motion artifacts limit evaluation, the report should not mention limitations.
• C. If motion artifacts limit evaluation, the report should exaggerate limitations to justify repeating the exam.
• D. If motion artifacts limit evaluation, demand immediate repeat imaging regardless of clinical status.

Answer: (C)

Motion artifacts can significantly degrade CT image quality and limit accurate interpretation. When this happens, the report should clearly state that the examination is limited by motion and describe how that affects confidence in evaluating the structures of interest. Provide constructive next steps: correlate with the patient’s clinical findings, and if clinically warranted, suggest a repeat study with optimized technique (such as breath-hold, faster acquisition, or motion-reduction strategies) or an alternative imaging modality better suited to the clinical question. The emphasis is on acknowledging the limitation and guiding appropriate next steps, not on exaggeration or forcing an immediate repeat without clinical justification.
