Medical Imaging Technologists are regulated health care professionals (except ultrasound) who perform diagnostic imaging procedures to detect disease and injury. Our Medical Imaging Technologists are part of the Joint Department of Medical Imaging (JDMI), which includes the departments at UHN, Mount Sinai Hospital and Women’s College Hospital.
Our technologists practice under standard protocols, policies and medical directives. Their scope of practice includes the use of ionizing radiation, electromagnetism and other prescribed forms of energy for the purposes of diagnostic and therapeutic procedures; the evaluation of images and data relating to the procedures; and the assessment of the patient before, during and after the procedure.
JDMI technologists specialize in:
Radiological technologists are responsible for producing diagnostic images, including x-rays, mammography, angiography, fluoroscopy, and computerized tomography (CT) scans.
Nuclear medicine technologists prepare and administer radiopharmaceuticals to the patient by means of injection, inhalation or ingestion, then take images to assess organ function. Nuclear medicine also uses radiopharmaceuticals to treat a variety of diseases including hyperthyroidism and thyroid cancer. PET/CT is a type of nuclear medicine imaging that can pinpoint molecular activity within the body and identify disease at its earliest stages by using small amounts of radioactive materials to help diagnose and treat a variety of diseases.
Magnetic resonance technologists work with magnetism and radio waves to acquire images to aid in diagnosis of disease. MRI produces images with excellent soft tissue discrimination.
Sonographers use high frequency sound waves to produce real-time images. The waves are transmitted to various organs, tissues or blood vessels and the returning echoes form an image. Ultrasound is frequently used in obstetrics to study the age, number, well-being and location of the fetus.
Medical radiation technologists are regulated by the
College of Medical Radiation Technologists of Ontario (CMRTO).
UHN is a work place where you will enjoy the unique challenges of your chosen field, create and engage in best practices, and you will be at the heart of facilities bringing the world new health care innovations.
