CAR Practice Guidelines on Breast Imaging and Interventions: Mammography and Digital Breast Tomosynthesis

Area of Science:

• Radiology
• Medical Imaging
• Oncology

Background:

• The Canadian Association of Radiologists (CAR) previously published consolidated guidelines in 2016.
• Advances in digital imaging, tomosynthesis, artificial intelligence, and quality assurance necessitate updated recommendations.

Purpose of the Study:

• To provide evidence-based practice guidelines for mammography and digital breast tomosynthesis (DBT).
• To offer updated recommendations for screening and diagnostic breast imaging.
• To guide the integration of emerging technologies in breast cancer detection.

Main Methods:

• Development by the CAR Breast Imaging Working Group.
• Evidence-based review of current practices and technological advancements.
• Focus on clinical indications, technical standards, radiation dose, reporting (BI-RADS®), personnel qualifications, and performance benchmarks.

Main Results:

• Presents updated recommendations for mammography and DBT.
• Addresses key aspects including equipment, radiation safety, and quality assurance.
• Highlights the importance of integrating artificial intelligence and other new technologies.

Conclusions:

• Mammography and DBT remain central to breast cancer detection.
• The guideline supports the adoption of new technologies to improve diagnostic accuracy and efficiency.
• It serves as Part I of comprehensive CAR Breast Practice Guidelines, intended for use with other components and referral guidelines.
