Area of Science:

  • Medical Imaging
  • Radiology
  • Digital Health

Background:

  • Screen-film mammography (SFM) has been the standard for breast cancer screening.
  • Recent advancements in digital detector technology have led to the development of full-field digital mammography (FFDM) systems.
  • FFDM systems are approaching performance levels that make them realistic replacements for SFM.

Purpose of the Study:

  • To review the fundamental differences between FFDM and SFM systems.
  • To discuss the various technological approaches to FFDM development.
  • To highlight the inherent advantages of digital mammography.

Main Methods:

  • Overview of FFDM system development approaches including slot scanning, flat-panel detectors (scintillator/amorphous silicon, amorphous selenium), and computed radiography.

  • Comparison of image recording, display, and storage principles between FFDM and SFM.
  • Analysis of FFDM system characteristics and benefits.

    • Main Results:

    • Several distinct FFDM system designs are available.
    • FFDM offers significant advantages over SFM, including wider dynamic range and improved image processing.
    • Potential benefits include reduced recall rates, lower radiation doses, and increased patient throughput.

    Conclusions:

    • FFDM systems represent a significant technological advancement in breast imaging.
    • Despite higher initial costs, the advantages of FFDM support its adoption.
    • Technological progress will likely establish FFDM as a standard in breast evaluation.
