Aims and objectives
compression is given to the breast to reduce breast thickness,
tissue superposition and X-ray scattering to get a good image quality.
The force-standardized compression mammography (FSCM) is the standard for population-based mammography screening and diagnostic imaging.
there are no general accepted guidelines for compression force to obtain good image quality.It has been reported that a lot ofvariation existsbetweentechnicians and hospitals.

Methods and materials
A retrospective studyof mammogramswas executed in 100 participantsof the Belgian population-based screening (50-69 years old).
The mammographic screening examinations of 2016 used a conventional compression paddle on the mammography system (FSCM).
we introduced a newly developed compression paddle with a real-time pressure indicator (PSCM).
We compared the DICOM data per patient before (2016) and after (2018) the introduction of a pressure-standardized compression mammography...
A total of 400 prior and 400 current mammographic images of 100 women were analyzed. - 17 participants were excluded due to different exposure control modes for prior and current mammograms. - Mammograms of 83 participants (332 FSCM and 332 PSCM images) were included for further analysis. - Mean compression pressure increased from 11.56±6.4kPa to 12.78±3.4kPa (p<0.0001) after the introduction of the PSCM. Fig. 2 - The percentage of mammograms in the target pressure range of 8-14kP (target...
Our study showed that when using PSCM (compared with FSCM),
the compression reproducibility within and between technicians improved with less variation.
a reduction of under- and over-compression was seen,
with an increased number of mammograms in the target pressure range of 8-14kPa.
By using a paddle with a real-time pressure indicator in PSCM,
the discomfort reduced,
due to a better alignment between technician and participant and closer participant involvement.
