X-rays can play a role in diagnosis and are taken when a need has been determined after taking a patient case history and conducting a physical examination. Most patients do not require X-rays. Chiropractors receive 360 hours of education in radiology covering a full range of topics from protection to X-ray interpretation and diagnosis. Governments in every province have recognized the training and competence of chiropractors to take and interpret X-rays and have granted them this right.
