Computer Aided Detection Programs (CAD)

How do computer aided detection programs (CAD) work?  Specifically, how do they alert the radiologist to suspicious areas when examing a mammography?

Thank you

CAD is a computer program ..... normally the Radiologist reads the films but when using CAD the computer program also evaluates the films and marks certain areas that need special consideration and those areas are looked at again, perhaps more closelly by the Radiologist.

Thank you for your response.  

1) Is there a permanent record of the areas the CAD marks as areas that need special attention?

2)  Does the Radiologist refer to any other written documentation than the report he dictates in order to track a particular area during follow-up six month intervals?

Sorry about the "ditto" responses .. I don't know how that happened.  LOL   ..  When reading a mammogram or ultrasound the Radiologist ALWAYS has all previous films at hand for comparison.  They don't rely on reports .... they compare the actual films. I don't believe  the CAD markings are actually on the film itself but can be replicated with the program when the film is viewed. I've never seen any markings on films .... it's on the computer screen when the films are viewed. Most films today are not actual films but on discs  (CD).

When I requested my films from the records department I was told they do not come in CD format.  Yet it was a digital mammogram screening with ImageChecker Computer Aided Detection System.

I'm not sure the films I picked up will be sufficient for a second opinion.  It sounds like the Doctor should have access to a computer program to benefit from the CAD.

Most institutions have the CAD program and it could be used if the Radiologist finds it necessary or even if it's routine. Is there some problem that you are getting a 2nd opinoin on your films ?? You've already had your biopsy I believe so I can't see the advantage of a 2nd opinion on the films now. Just curious .....

I have strong evidence to suggest the biopsy was taken in the WRONG quadrant of my breast.
