The ImageChecker CT Lung CAD system assists in the review of multi-slice CT chest exams to help maximize physician accuracy and efficiency in detecting actionable lung nodules as early as possible and tracking their size changes over time.

CAD and Multi-Detector CT (MDCT) Examinations
Computer-aided detection is used as "a second pair of eyes" by radiologists when reading CT chest exams. As with mammograms, radiologists review the CT exam then activate the CAD software and re-evaluate the marked area(s) before issuing a final report. The ImageChecker CT CAD system and related software components are designed to improve the accuracy in detecting lung nodules and address the information overload and efficiency issues that occur with MDCT chest exams. Clinical trials demonstrated that use of the ImageChecker® CT system can help increase the detection of actionable solid lung nodules by calling attention to potential abnormalities.

What is CAD?
Computer-aided detection (CAD) refers to sophisticated pattern recognition software radiologists use to help them read medical images. This software identifies various features on medical images and highlight them in order to decrease false negative readings. It does not replace the imaging technology; rather it is an interpretive aid used during image review. R2 Technology pioneered the use of CAD for mammography in 1998 when the ImageChecker® system became the first CAD system approved by the FDA for screening mammography. The ImageChecker CAD system was also the first system approved for use with diagnostic and digital mammography. More than eight million women a year have their mammograms interpreted with the aid of this leading CAD system. R2 Technology applied its mammography CAD expertise in the area of multi-detector CT (MDCT) chest exams and in July 2004 received FDA approval for its ImageChecker® CT CAD system, the first CAD system to receive approval for the detection of solid lung nodules during review of MDCT chest exams.
