CAD (Computer Aided Detection)
CAD is a computer system that has
built in algorithms that are very sensitive in detecting minute density
difference on an image. These density changes are important because they could
represent cancerous lumps. The mammogram is performed and the images developed.
Once developed the mammogram films are run thru a digitizer which electronically
digitizes the images and puts marks on the area where it detects minor changes
in density, many are often too small to be seen by the human eye. These images
are then sent to the viewing part of the CAD unit where the Radiologist will
view the mammogram films and compare them to the CAD images. The CAD unit has
been proven to increase sensitivity in detecting early cancers by as much as
20%. The Radiologist still has to make the final decision on whether or not the
areas marked by the CAD unit need further follow up or not.
St. Mary's recently purchased an installed a CAD unit and will be utilizing the
technology in our mammography program, because breast cancer affects so many
women and can be so devastating, St. Mary's is committed to having the most up
to date technology. This does not require any additional procedure for the
patient.
There is a slight fee increase associated with the CAD, however most insurance
companies consider it reimbursable.
