Chinese researchers have completed a comparison study of the effectiveness of conventional coronary artery angiography (CCA) to computed tomography angiography (CTA) and cardiac magnetic resonance imaging (CMR) in imaging coronary lesions. The study, presented at this week’s American Heart Association Scientific Sessions in Chicago, looked at twenty-eight middle-aged patients that reported experiencing chest pain but that had not undergone bypass surgery or other interventions. CCA studies were performed in conventional fashion, while the CTA was performed with a Multislice 64 CT scanner and CMR with a 1.5 Tesla scanner. Upon a review of the results, the researchers determined that “64 Slice CTA provides high diagnostic accuracy in assessment of coronary stenosis,” the team wrote in a summary. Essentially, using 64 slice scanning for angiography results in fewer false negatives as compared to conventional CCA.
