Medical imaging allows radiologists to see inside the body, helping them detect potential concerns and share those findings with your physician. For certain exams, such as computed tomography (CT) and magnetic resonance imaging (MRI), a contrast material (also called contrast dye or contrast agent) may be used. The contrast material helps highlight specific structures, making it easier to identify abnormalities.
The type of contrast material depends on the type of medical imaging your physician has requested. It is not a permanent colouring agent, but a temporary substance that changes how X-rays or magnetic fields are absorbed or reflected by tissues. This creates clearer separation or “contrast” between different areas of the body, improving the visibility of organs, blood vessels, and tissues.
A CT scan uses a combination of X-rays and computer technology to produce comprehensive images of specific areas of your body, including your bones, chest, head, joints, lungs, and spine. CT scans provide more detail than regular X-rays and can detect conditions that may not be visible with other imaging methods.
If a CT scan requires contrast, it may be administered either intravenously or orally:
MRI uses a strong magnetic field to provide very clear images of the body and is often ordered to help diagnose stroke, aneurysms, or multiple sclerosis. Using magnets and radiofrequency waves MRI can help find diseases of the brain, spine, skeleton, abdomen, and soft tissues.
An MRI uses a different type of contrast material, gadolinium-based compounds. Gadolinium alters the magnetic properties of nearby water molecules, enhancing the visibility of tissues on MRI scans. It is administered intravenously. Most patients do not notice any sensation, although a few will experience a cold feeling in the arm during the injection.
Contrast materials are safe and rarely produce side effects, such as allergic reactions. However, certain allergies and medical conditions, such as kidney disease, can increase your risk of side effects. While reactions are rare, we are well-equipped to deal with them.
When booking your exam, you will be asked about your allergies, medical conditions, and any previous reactions to contrast materials. This information helps us identify if you may be at higher risk for complications. Please answer these questions carefully, and include details about your current medications, health conditions (including allergies or pregnancy), and any past contrast-related reactions.
After your exam, your body will absorb or naturally eliminate the contrast material through urine or bowel movements. Drinking plenty of water can help this process along. Most people feel completely fine afterward, but if you notice unusual symptoms, such as diarrhea, nausea, or vomiting, contact your doctor. If you ever experience signs of an allergic reaction, like difficulty breathing, itching, or hives, call emergency services immediately.
We do our best to have our radiologists interpret the imaging and forward the results to your doctor in a timely manner. Please consult with your doctor regarding your results and any follow up exams or questions.
In Calgary, CT and MRI exams are provided at our Mayfair Place location as private pay exams and are not covered by Alberta Health Care. Prices are per body area. If additional body areas are scheduled within the same appointment, discounts apply. For example, the abdomen is one body area, while the spine is divided into three body areas. We also offer CT Health Assessment packages.
In Saskatchewan, we provide MRIs as a publicly funded, community-based service under contract with the Saskatchewan Health Authority and as a private pay exam. Private MRI services in Saskatchewan are provided in accordance with and under the legislation of the Province of Saskatchewan. Prices are per body area. If additional body areas are scheduled within the same appointment, discounts apply.
We offer a 10% Seniors discount (65+) that can be applied to the first exam.
Your health spending account or group medical insurance plan may cover the cost of a private CT or MRI that is prescribed by a qualified health care practitioner. You will need to check with your plan administrator for coverage details.

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.
