Rcadia Medical Imaging, a leading developer of systems for computerized analysis of medical images particularly for patient triage in emergency and life threatening conditions, announced that it has been awarded FDA 510 (k) marketing clearance for an enhanced version of its COR Analyzer® System to assess coronary branch vessels in addition to main coronary arteries in patients with suspected coronary artery disease (CAD).

The clearance is the third for the COR Analyzer System, a unique clinical decision support tool that automatically detects significant (50 % and over) stenosis in coronary arteries from Coronary CT Angiography (cCTA) studies.

Shai Levanon, President and CEO of Rcadia, said: "The enhanced version expands the benefits of the COR Analyzer System as a powerful complement to cCTA in evaluating suspected CAD patients. By providing rapid detection of stenotic lesions our system enables expanded use of cCTA to enhance patient care and reduce unnecessary costs."

The FDA clearance comes after the recent publication of the first clinical study evaluating the COR Analyzer's enhanced version. The study, published (online) in Academic Radiology, in January 2011 by researchers at Thomas Jefferson University, showed that the "COR Analyzer provides a high negative predictive value for the absence of coronary disease in branch vessels as well as the major coronary arteries."

The retrospective study, conducted by Ethan Halpern, MD, and David Halpern, compared 207 patients examined by the COR Analyzer System with expert interpretation. The final clinical interpretation identified 48 patients with significant (over 50 percent) stenosis. In the study, the COR Analyzer System demonstrated a sensitivity of 92 %, negative predictive value of 97 %, specificity of 70 % and a positive predictive value of 48 %.

The researchers noted that the "high negative predictive value will be most useful in a population with a low prevalence of coronary disease - such as the emergency room chest pain population - where the COR Analyzer might be used to facilitate the rapid discharge of a majority of patients who have normal coronary CTA studies during all hours of the day or night."
