As a medical imaging provider, Mayfair Diagnostics is committed to providing our patients with the very best imaging experience possible. An important part of this process includes addressing any questions or concerns our patients may have.
We often receive questions from our patients about radiation safety during medical imaging, so we created this infosheet to illustrate how radiation from medical imaging compares to other sources of radiation exposure. Below we’ve also answered some common questions about this topic.
At Mayfair, we use two types of electromagnetic radiation to produce images of your body. The first type is X-rays, which are used in several of our exams, including:
During these procedures X-rays are passed through your body and some of them get absorbed. The X-rays not absorbed create the image, while those that are absorbed contribute to your radiation dose.
The second type of electromagnetic radiation, gamma rays, is used by nuclear medicine imaging. Gamma rays are introduced intravenously (in the form of a radiopharmaceutical) and emit outward to the detectors. These rays can also be combined with CT imaging, which uses X-rays, to produce very detailed images of your body.
All exposures of radiation are held to the standard of ALARA (as low as reasonably achievable) for all medical imaging exams that involve radiation. This means that no or low exposure is best, and the risk-benefit ratio should always be considered.
Radiation dosage is measured in millisieverts (mSv). When talking about the risks of radiation exposure, we are referring to possible side effects, such as the chance of developing cancer later in life. If medical imaging is recommended, your doctor will consider the benefits of an accurate diagnosis and compare it to the small risk of radiation exposure This chart from the Radiological Society of North America compares approximate background radiation levels and effective radiation doses in adults for common radiology procedures.
Health care governing bodies have created guidelines to ensure patient safety is a priority. Health care practitioners are encouraged to order X-rays only when necessary, and only when the benefit outweighs the small risk of exposure.
At Mayfair, we take each patient’s history to help us understand the reason for the exam and evaluate any potential risks. For exams with higher potential radiation exposure, our technologists check patient histories for records of previous imaging and coordinate with a radiologist to confirm the specific number and type of images. Lead shielding is also available to cover vulnerable areas of the body.
During each patient appointment, we make sure that patients understand the purpose of their exam, that we have their consent, and that consent is based on a true representation of the benefits and risks of each procedure.

Radiologists are specialized physicians who interpret diagnostic imaging to diagnose and monitor a wide range of medical conditions. At Mayfair Diagnostics, they review X-ray, ultrasound, CT, and MRI studies, among others, analyzinsg images in detail and providing comprehensive reports and clinical recommendations to referring physicians. They collaborate closely with technologists and clinic teams to guide imaging protocols, ensure quality and radiation safety standards, and may perform image-guided procedures such as biopsies or injections. Through their expertise and teamwork, radiologists play a key role in accurate diagnosis, effective treatment planning, and improved patient outcomes.
Administrative professionals support the organization across human resources, marketing, operations, strategic partnerships, finance, information technology, and infrastructure. From recruiting staff to promoting services and improving workflows, they help ensure smooth operations and positive experiences for employees and patients. Through collaboration with clinical and support teams, they provide essential coordination that enables efficient, high-quality service.
Diagnostic Imaging Assistant (DIA) support clinic operations and help ensure a positive patient experience. They assist staff by greeting and preparing patients, confirming information, coordinating appointments, and guiding patients through their visit. DIAs also maintain exam rooms, manage documentation, and ensure supplies and equipment are ready. Through strong customer service, attention to detail, and teamwork, they help create a safe and organized environment.
Patient Experience Coordinators (PECs) are the first point of contact, scheduling exams and ensuring accurate patient information. They communicate clearly with patients, coordinate with care teams, and support a smooth, confidential, and customer-focused experience.
Nuclear Medical Technologists perform diagnostic nuclear medicine procedures involving sensitive and highly personal patient circumstances. They are responsible for delivering the highest standard of care in a professional, compassionate, and patient-centered manner, in accordance with provincial regulatory requirements, CAMRT standards, and Mayfair policies and guidelines.
Computed Tomography (CT) Technologists operate CT imaging equipment to produce detailed cross-sectional images of the body that assist in diagnosing a wide range of medical conditions. They prepare and position patients for scans, ensure safety protocols are followed, and administer contrast agents when required. CT technologists work closely with radiologists to ensure high-quality diagnostic images are obtained, while providing clear communication and compassionate care to support patient comfort throughout the procedure.
Magnetic Resonance Imaging (MRI) Technologists operates MRI scanners to produce detailed images of internal body structures used to assist in medical diagnosis and treatment planning. They are responsible for preparing and positioning patients, ensuring all safety protocols are strictly followed due to the strong magnetic field, and obtaining high-quality images as directed by radiologists. MRI technologists combine technical expertise with patient care, providing clear communication and support to ensure a safe, comfortable, and efficient imaging experience.
Diagnostic Medical Sonographers perform ultrasound exams to help diagnose and monitor medical conditions. Following Sonography Canada standards and Mayfair Diagnostics protocols, they capture accurate images while ensuring patient safety, comfort, and confidentiality. They work with radiologists and clinical teams to review requisitions, prepare patients, perform scans, and document findings, contributing to accurate diagnoses and a positive patient experience.
Medical Radiation Technologists (MRTs) perform x-ray, mammography, and BMD exams while ensuring patient safety, accuracy, and compassionate care. They also may assist in pain therapy procedures. MRTs verify patient information, explain procedures, position patients, and produce high-quality images. MRTs follow professional standards and protocols, maintaining strict radiation safety, quality assurance, and patient privacy while supporting a positive patient experience.
