Digital Mammography with CAD and AI: How to Evaluate the Software

Digital mammography with CAD: what traditional CAD does

Classical CAD analyses a mammogram and marks regions that may represent masses or microcalcifications, acting as a second look for the reader. The radiologist remains responsible for the interpretation, and the marks are prompts, not diagnoses. Billing and reporting rules sometimes distinguish a diagnostic mammography with or without CAD bilateral, so confirm how your facility records it.

A CAD result is only useful if it is displayed in the same viewer as the images, can be switched on and off, and is archived with the study. Ask how the marks are stored, typically as a DICOM structured report or overlay, and whether prior studies keep their CAD results.

AI in mammography: current uses

Modern AI software for mammography can support several tasks: flagging suspicious cases for priority reading, suggesting lesion locations, estimating breast density, and in some products assisting with quality checks on positioning. Some tools work as a concurrent reader, others as a triage or double-reading aid.

Performance claims differ by product and by study population, and results from one population cannot be assumed to apply to another. Ask for independent validation data, the regulatory status of the software in your jurisdiction, and whether the vendor will help you run a local pilot on retrospective cases.

• Triage: cases flagged for priority review
• Concurrent reading: marks or scores shown with images
• Density assessment: consistent categories
• Quality support: positioning or technical checks

Tomosynthesis with CAD and AI: extra considerations

Tomosynthesis datasets contain many slices, so AI can save time by pointing to the slice where a finding is best seen. At the same time the software must handle the larger data volume without delaying delivery to the reading station. Confirm whether the algorithm is trained for tomosynthesis or only for 2D, and whether it works on the synthetic 2D image if one is used.

The Villa Melody IIID TS has integrated tomosynthesis and can be connected to AESTIMAX or WorkstationONE reporting stations with optional AI tools. The base Melody IIID offers the same reporting-station connectivity and can be upgraded in the field to tomosynthesis.

Integration with the workstation and PACS

The software is only as good as its integration. Specify where the AI engine runs (on the workstation, a server or a cloud service), how data privacy is handled in line with UAE rules, how long processing takes, and how results appear in PACS and the report. A tool that adds a minute of waiting to every case will be disabled by busy radiologists.

Check also failure modes: what happens if the AI server is unavailable, and can images still be read normally? Our guide to digital mammography systems and detectors describes how image quality at the source affects any downstream algorithm.

Procurement questions and next step

Ask the supplier for the intended use statement, regulatory status, training data description, performance on tomosynthesis and 2D separately, licensing model, and the update policy. Clarify who is responsible for clinical governance and for monitoring performance over time.
