Home CAN ABUS IMPROVE BREAST CANCER DETECTION?
Several studies have looked at the benefits of adding handheld breast ultrasound and automated breast ultrasound (ABUS) to a screening mammogram. Results have shown that it increases cancer detection and sensitivity, particularly in cases of women with dense breasts.
Automated breast ultrasound uses high frequency sound waves to take 3D images of the whole breast, targeting specific areas and ensuring they are displayed in a reproducible fashion. It’s a fast and almost painless procedure which can look at both breasts in about 15 minutes. ABUS is especially beneficial to women with dense breast tissue.
You can’t tell by look or feel whether or not you have dense breasts. It’s a diagnosis that can only be assessed by mammography. Dense breasts have less fat and more glandular and connective tissue. On a mammogram, fatty tissue looks dark, while both dense tissue and tumours look white, making them hard to detect. The white-looking breast cancers are easier to see on a mammogram when they’re surrounded by dark-looking fatty tissue.
For women with dense breast, a mammogram may be harder to read, so smaller cancers may be hidden. At Mayfair Diagnostics, we use the Volpara Health Technologies program which scores breast density from A to D:

In cases of high breast density, ABUS allows the technologist to check the breast from a variety of angles offering more accurate interpretations. For extremely dense (Volpara D), or heterogeneously dense breast tissue (Volpara C) combined with additional risk factors for breast malignancy, Mayfair recommends supplemental ABUS or handheld breast ultrasound, in addition to regular mammograms.
Dense breast tissue increases the risk of breast cancer, especially in older women. For women with dense breast tissue in 75 percent or more of their breasts, their breast cancer risk is double relative to the general population.
Mammography is still the gold standard for breast cancer screening. However, women with very dense breasts may require a more personalized screening approach than what is recommended for the general population. This may include both mammography and ultrasound exams.
Mayfair Diagnostics has 14 mammography locations, which have all been updated recently with the newest technology. Thirteen of our mammography locations also feature patient-assisted compression – which helps provide a more comfortable mammogram. Coventry Hills has an upgraded mammography system but doesn’t offer patient-assisted compression.
Automated breast ultrasound is available at our Market Mall, Mayfair Place, Southcentre, and The CORE locations. Please visit our breast imaging services page for more information.

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.
