CMRTO response: The CMRTO sets the requirements for an MRT's registration in each of the specialties of radiography, nuclear medicine, radiation therapy and magnetic resonance and in the near future, diagnostic medical sonography. MRTs are responsible for ensuring they have the requisite knowledge, skills and judgment to perform procedures safely and effectively in every area of their practice. This means you must not perform any procedure unless you are competent to do so, and you must practice only in the areas of medical radiation technology in which you are educated and experienced.
One way to demonstrate that you have the necessary education and experience is to complete a certification in a specialty area offered by a professional association or other organization. In fact, your employer may require MRTs and DMSs to complete a certificate in a specialized area of practice before practising in that area.
