Am I a Candidate? — Interactive LDRT Candidacy Check

Five questions based on the 2026 ARS Appropriate Use Criteria help you consider whether low-dose radiation therapy (LDRT) may be worth discussing with your doctor. Your answers stay on this page only: the checker uses on-page React state, sends nothing to our server, uses no cookies, keeps no server log, and has no analytics on your answers. Everything resets when you leave. The result is for education only and is not medical advice or a diagnosis. Only a physician who reviews your full history, examination, and imaging can determine whether LDRT is appropriate for you.

Five questions, about one minute

• How old you are
• Which joints bother you, including knee, hip, shoulder, hand or fingers, thumb base, foot or ankle, spine, or another joint
• The type of arthritis you have been told you have
• What standard treatments you have tried
• Whether pregnancy, a joint replacement, prior radiation to the same area, or active infection could affect candidacy

Evidence is strongest for knee, hip, and shoulder osteoarthritis; evidence is more limited for hand, thumb, foot, and ankle joints. The spine has limited published data and is not a well-established ARS AUC indication. Reading rather than clicking? See the full ARS AUC summary. If LDRT may be worth discussing, use the Doctor Discussion Guide for your appointment.
