Can Breast Compression Be Reduced in Digital Mammography and Breast Tomosynthesis?

Area of Science:

• Radiology
• Medical Imaging
• Breast Imaging

Background:

• Breast compression is a standard procedure in mammography and digital breast tomosynthesis (DBT).
• Patient-reported pain during mammography can be a barrier to screening adherence.

Purpose of the Study:

• To assess the impact of reduced breast compression on pain perception and image quality in mammography and DBT.
• To determine if lower compression forces maintain diagnostic adequacy.

Main Methods:

• A two-part study involving women undergoing mammography.
• Part 1: Assessed pain, thickness, and coverage at four compression levels (no imaging).
• Part 2: Acquired DBT images at standard and reduced compression, evaluated by radiologists for artifacts and coverage.

Main Results:

• A feasible force reduction of approximately 47-48% significantly decreased perceived pain.
• Reduced compression led to a slight increase in breast thickness but no significant change in tissue coverage.
• No increase in motion blurring or diagnostic artifacts was observed with reduced compression.

Conclusions:

• Mammography and DBT can potentially utilize reduced compression forces (around 50%).
• Lowering compression significantly reduces patient discomfort without clinically compromising image quality or coverage.
• This approach may improve screening participation by mitigating pain.
