A patient arrives for a thoracic spine X-ray and has had two thoracic examinations in the last four months. How should you handle justification?

• A. If referred from GP: Ask patient if anything has changed, then discuss with radiologist.
• B. If referred from outpatient clinic: Discuss with referring clinician, explain they have had recent prior imaging as they may not have realised. If I still don't believe the imaging to be justified, discuss with a radiologist. In both situations I would document that the case was discussed with a radiologist.
• C. Document that the case was discussed with a radiologist.
• D. Do not discuss with radiologist.

Answer: (C)

Justification hinges on ensuring an imaging exam will add value for the patient while minimizing radiation exposure. When a patient has had two thoracic examinations within a few months, it’s important to confirm that a further X-ray is truly needed and that the decision has been reviewed by a radiology professional. The best action is to document that the case was discussed with a radiologist. This creates a clear record that a radiologist reviewed the prior images and weighed the potential benefit against the risk, providing an auditable justification for proceeding. It also supports safe practice and accountability, especially in situations where cumulative exposure could be a concern. If uncertainties remain, involvement of the referring clinician can occur, but the essential, best-supported step is recording that the radiologist’s input was sought and the justification was considered.
