Important Issues

Before requesting an imaging investigation, the referring doctor must ask him/herself the following questions:

  1. Have I taken a history, performed a physical examination and come to a provisional clinical diagnosis? (the significance of the result of a test cannot be assessed without a pre-test probability of the disease being tested for)

  2. Is imaging indicated?
    • Am I duplicating recent tests?
    • Will it change my diagnosis?
    • Will it affect my management?
    • Will it do more harm than good?

  3. If imaging is indicated, is a test that does not employ IR a feasible option (Ultrasound or MRI)?

  4. If an imaging investigation is required, have I defined the clinical problem adequately on the request form
