Non-invasive coronary CTA cost-effective alternative to invasive cardiac catheterization for CAD evaluation

According to a study conducted at Thomas Jefferson University (TJU), non-invasive coronary computed tomography angiography (CTA) is a cost-effective alternative to invasive cardiac catheterization in the care of patients who have positive stress test results but a less than 50 percent chance of actually having significant coronary artery disease (CAD). The study will be published in the May issue of the American Journal of Roentgenology.
