Higher intracoronary attenuation improves diagnostic accuracy in MDCT coronary angiography

2006

OBJECTIVE: The purpose of this study was to investigate whether the amount of intracoronary attenuation influences the diagnostic accuracy of MDCT coronary angiography in the detection of clinically significant stenosis. MATERIALS AND METHODS: One hundred twenty patients in sinus rhythm with suspected coronary artery disease who underwent MDCT of the heart and conventional coronary angiography were retrospectively selected. The population was divided into two groups depending on median (326 H) coronary vascular enhancement (i.e., low attenuation and high attenuation). The diagnostic accuracy of MDCT for the detection of clinically significant coronary artery lesions (> or = 50% lumen reduct…
