Magnetic resonance technologists (or MRI technologists), produce diagnostic images using equipment that generates radio waves and a strong magnetic field. They apply their extensive knowledge of anatomy, pathology and physiology, as well as their patient care skills, to obtain images and monitor patients during scans.
Unlike x-rays, MRI uses magnetic fields and radio waves to make images. MRI can be used to:
- study the vascular system
- find tumours, especially in the brain and spine
- make images of soft tissues such as muscles and tendons
Because MRIs are a unique type of technology, they require special considerations for patient care and safety. MR Technologists are responsible for anyone (patients, staff, visitors) who comes in contact with the MRI’s powerful magnetic field. MR Technologists set the machines and related equipment to operate properly. When patients need contrast media (dye) to make images visible, the MR Technologists are the ones who inject it. During the scan, the MR Technologist checks the images as they show up on the monitor.
The Alberta College of Medical Diagnostic and Therapeutic Technologists (ACMDTT) has adopted the Canadian Association of Medical Radiation Technologists’ (CAMRT) competency profiles for the medical radiation technology specialties that it regulates. Previous competency profiles for these specialties have been rescinded. The ACMDTT acknowledges that CAMRT’s profiles reflect current practice in Alberta.
