New mammography software from VIDAR
5 February 2006
Herndon, Va, USA. VIDAR Systems Corporation has released Clinical Express
3.0 software for mammography. Used with the VIDAR CAD PRO Advantage Film
Digitizer, it allows prior film-based studies to be digitized and then
reviewed alongside new studies on digital mammography workstations.
The digitizer features patented technological innovations that deliver
superior image quality, exceptional consistency and repeatability, and
increased speed. A study conducted by Johns Hopkins University supports the
use of digitizing prior mammography studies for reference and review.
According to the study, there were few differences in the ability of
radiologists to read mammography films digitized by the CAD PRO Advantage
compared with hard-copy originals. The study has been finalized and
submitted for Peer Review.
Brian Beardslee, vice president of VIDAR's Medical Business, said the CAD
PRO Advantage and Clinical Express 3.0 will play a key role in busy
radiology departments as adoption of digital mammography rapidly increases,
especially in light of a recent Digital Mammographic Imaging Screening Trial
(DMIST) that found that digital mammography is more sensitive for some
According to the Johns Hopkins study, 120 mammography examinations were
selected from the hospital's Radiology Department film library representing
a range of patients who had screening or diagnostic procedures. Eight
radiologists interpreted all 120 examinations, half as originals and half as
digital images on a workstation. Receiver operator characteristic analysis
was performed, with the results showing that there was no statistically
significant difference between film and soft copy interpretations.
