Right study, first time.

    Type an indication — get the imaging studies the ACR rates for it, with adult and pediatric radiation levels. Built directly from the ACR Appropriateness Criteria: 297 topics, 1,336 clinical scenarios, 15,823 procedure ratings.

    For educational reference only. Clinical decisions require physician judgment of the individual patient. Recommendations come directly from published ACR Appropriateness Criteria; this tool does not generate them.

    How to use this tool

    Ask mode Type the indication, symptom set, or scenario in plain language — for example, "right lower quadrant pain with fever, suspected appendicitis". We match it to the closest ACR clinical scenario and return the studies the ACR rates for it, with adult and pediatric radiation levels. Patient vernacular is fine: "worst headache of life", "kidney stone", "PE workup".
    Browse mode Walk the published structure: pick an ACR panel (e.g., Gastrointestinal, Neurologic), then a topic, then a clinical variant. Each variant returns the same procedure ratings and radiation levels — it's the deterministic path when you know exactly what you're looking for, or when Ask mode doesn't land on a confident match.
