Summary

Optimal breast compression during mammography is crucial. Insufficient force may increase patient discomfort without improving image quality, impacting screening effectiveness.

Area of Science:

  • Radiology
  • Medical Imaging
  • Breast Health

Background:

  • Mammography utilizes breast compression to enhance image quality and reduce radiation dose.
  • The relationship between compression force, breast thickness, patient discomfort, and image quality requires further investigation.

Purpose of the Study:

  • To investigate the correlation between applied compression force, breast thickness, and patient-reported discomfort during mammography.
  • To assess the impact of varying compression levels on mammographic image quality.

Main Methods:

  • A prospective study involving women undergoing routine mammography.
  • An additional craniocaudal (CC) view was acquired using reduced compression (10-30 N).
  • Measurements of breast thickness, patient discomfort, and radiologist assessment of image quality were recorded.

Main Results:

  • 24% of women showed no reduction in breast thickness with decreased compression.
  • Reduced compression led to increased patient discomfort without improving image quality in some cases.
  • Radiologists observed decreased contrast resolution in fatty breast tissue with reduced compression, indicating lower image quality.

Conclusions:

  • Breast compression effectiveness varies among individuals, with some experiencing no thickness reduction.
  • Applying insufficient compression may increase discomfort without yielding diagnostic benefits.
  • Mammographic compression force should be optimized to balance image quality and patient comfort.
