Which images can be CAD-analyzed?
All images to be analyzed by the SLDU must have been generated on a licensed Senographe system.
The SLDU algorithm will analyze any raw (RAW) full breast mammographic image.
The following images cannot be analyzed:
•
Processed (PROCESSED) and secondary capture (SCPT) images.
System performance is not assured for the following views:
•
Segmented views of the breast.
•
Implant views with the full implant imaged. Implant Displaced views with a maximum of 25 mm (1") of
breast implant imaged can be analyzed.
•
Special diagnostic images (e.g., magnification views, or spot compression views).
•
Cleavage views.
•
Images with hook wires.
•
Collimated images.
•
Coned images.

Which image formats can be displayed with CAD markers?
The following image formats can be displayed with CAD markers:
•
RAW images
•
Processed images
•
Premium View images, for users who have the Premium View Option on the review workstation.

Selecting images for CAD analysis
•
You can choose to use CAD to process an individual image, a set of images, a series, or an entire
patient case.
raw
•
Only
images can be CAD-processed. If you send an entire patient case to the SLDU, the raw
images are CAD-processed; other images present (processed or secondary-capture images) are
ignored, but increase the time required to obtain the overlays.
•
To obtain the best analysis of available information, send entire patient cases (rather than individual
images) to be CAD-processed. The SLDU takes advantage of all available information during
analysis. If different views of the same breast are present, the SLDU uses all screening views in its
analysis, just as a clinician would.
However, note that this increases the time required to obtain the overlays; processing a 4-view exam
takes two minutes, as opposed to 30 seconds for a single view.
•
To minimize the elapsed time before CAD overlays are available, send only raw images.
