Nuclear Medicine & Molecular Imaging Technology

Nuclear Medicine is an imaging method used to safely detect disease in its early stages. The practice of Nuclear Medicine, which includes Positron Emission Tomography (PET), involves the use of radioactive tracers administered either by injection, orally, or inhalation. Special cameras, computers and radioactive tracers are used to image how disease or treatments alter organ system function.

Nuclear Medicine Imaging involves non-invasive procedures that often eliminate the pain and trauma and risk associated with invasive surgery that patients would otherwise undergo, to determine the location and size of tumours, or the extent of numerous diseases in almost all of the human organ systems. It is able to non-invasively image and measure the body’s organs as they function, such as the amount of urine the kidneys produce per minute, the volume of blood ejected from the heart with each beat, and the extent of damage to the heart muscle due to a heart attack.

Molecular Imaging utilizes specialized instrumentation alone, or in combination with targeted imaging agents, to visualize biochemical events at the cellular and molecular level in order to help identify regions of pathology and potential mechanisms of disease.

What does a Nuclear Medicine Technologist do?

Nuclear Medicine Technologists work closely with doctors, and other members of the health care team. Ranging from cardiology to psychiatry, nuclear medicine images and treatments are used by a wide array of medical specialties. Nuclear Medicine Technology can save patients the pain and trauma associated with investigative surgery. The detailed images that nuclear medicine scans produce can determine the location and size of tumours or diseases. Nuclear Medicine Technologists:

  • Prepare and administers radiopharmaceuticals to aid in imaging organs and bodily functions
  • Use sophisticated computers to process data and enhance images for improved quality
  • Analyze biological specimens in the laboratory to aid in diagnosis

Modalities such as X-ray, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), Ultrasound (US), Positron Emission Tomography (PET), and Image Guidance for Radiation Therapy will be explored. Additional topics relating to the imaging modalities will be covered including Informatics, Artificial Intelligence/Machine Learning and Interventional Radiology.


Patient Care in Medical Radiation Sciences I (PMRS111/MRS227H1)

Examining a variety of fundamental patient care topics using a patient-centred lens, learners will be introduced to the professional, ethical, and legal standards which will be reinforced throughout the Medical Radiation Sciences (MRS) curriculum. Patient care skills will be enhanced through the study of communication, medical terminology, infection control, clinical assessment techniques and relevant pharmacology, including contrast media. This course will also provide the opportunity to develop communication and care-delivery strategies for diverse patient populations. Reflective practice will be introduced and developed throughout the course as learners work towards becoming reflective practitioners.


Anatomy for Medical Radiation Sciences (ANAT110/MRS159H1)

This course is an introductory course designed to serve as the foundation in Human Anatomy for students in the Medical Radiation Sciences program. The course will introduce learners to the components of the human body, relationships of the surface anatomy and the body’s internal components and discuss the basic function of these components. The course will encompass a regional approach to study the human body with correlation to its clinical application. Anatomy for MRS will serve to prepare learners for ANRD121/MRS163H1 (Relational Anatomy).


Nuclear Medicine Physics and Radiobiology (RANM110 / MRS133H1)
