These outpatient imaging efficiency measures give you information about hospitals’ use of medical imaging tests (like mammograms, MRIs, and CT scans) for outpatients based on the following goals:

• Protecting patients’ safety (like keeping patients’ exposure to radiation and other risks as low as possible);
• Following up properly when screening tests like mammograms show a possible problem; and,
• Avoiding the risk, stress, and cost of doing imaging tests that patients may not need.
