MAMM REPORT, a novel mammography report-coding system, effectively generates acceptable radiographic reports and achieves significant data compression. This system demonstrates superior data compression compared to standard Huffman encoding for brief mammographic reports.

Area of Science:

  • Radiology
  • Medical Informatics
  • Computer Science

Background:

  • Report-coding systems aid radiologists in generating radiographic reports.
  • Current systems involve selecting bar codes, keywords, or screen items.
  • MAMM REPORT is a microcomputer-based system specifically for mammography reporting.

Purpose of the Study:

  • To evaluate the MAMM REPORT system for generating mammographic reports.
  • To assess the data compression capabilities of MAMM REPORT.
  • To compare MAMM REPORT's compression efficiency against Huffman encoding.

Main Methods:

  • MAMM REPORT utilizes a question-and-answer format with mouse interaction.
  • It enables digital image labeling and data compression.
  • Sixty mammographic reports were coded using MAMM REPORT and evaluated by mammography specialists.

Main Results:

  • All 60 coded mammographic reports were deemed acceptable replacements for original reports.
  • MAMM REPORT achieved a data compression ratio of 135:1.
  • Huffman encoding yielded a compression ratio of 1.1:1, proving less effective for brief reports.

Conclusions:

  • Report coding systems can achieve substantial data compression for radiographic reports.
  • MAMM REPORT is a viable tool for generating mammographic reports and enhancing digital radiology workflows.
  • Standard Huffman encoding is not optimal for compressing concise mammographic reports.
