CT Software Helps Rule Out Coronary Artery Disease
The COR Analyzer system, from Rcadia Medical Imaging, automatically detects significant (50 percent and more) stenotic lesions in coronary arteries from coronary CT Angiography (CTA) studies.
The system provides a high negative predictive value for the absence of coronary disease in branch vessels as well as the major coronary arteries.
In studies, it has demonstrated a sensitivity of 92 percent and a negative predictive value of 97 percent. The system's specificity was 70 percent and the positive predictive value was 48 percent.
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. In these populations, the system could be used to facilitate the rapid discharge of a majority of patients who have normal coronary CTA studies.
