Breast imaging – Mammography technique – Pitfalls in techniques of mammography – Inadequate breast compression


If the breast is not compressed enough (less than 7 kg), there will be insufficient reduction in tissue thickness to provide diagnostically acceptable image contrast.

Probable cause – inadequate breast compression
Inadequate breast compression may occur if the breast slips out of the compression paddle. A retroareolar lesion may not be well delineated.

  • Ensure adequate breast compression on CC view to delineate isodense opacity in the retroareolar region.
  • Ensure that the breast does not slip out.
