摘要: Abstract Objectives We evaluated the accuracy of contrast-enhanced multidetector spiral computed tomography (MDCT) for noninvasive detection and classification coronary plaques compared it with intracoronary ultrasound (ICUS). Background Noninvasive determination plaque composition burden may be important to improve risk stratification monitor progression atherosclerosis. Methods included 46 consecutive patients a distinctive profile, who were investigated by ICUS (Goldvision, 20 MHz, Jomed Inc., Rancho Cordova, California). Due inability slow heart rate below 65 beats/min (n = 7) due renal insufficiency 2), nine could not studied MDCT (Sensation 16, Siemens, Forchheim, Germany). Results In remaining 37 patients, 68 vessels ICUS, 58 these visualized image quality sufficient analysis. that divided in 3-mm sections, correctly classified 62 80 (78%) sections containing hypoechoic areas, 87 112 hyperechoic 150 158 (95%) calcified tissue. 484 525 (92%) atherosclerotic lesions excluded. The MDCT-derived density measurements within revealed significantly different values (49 HU [Hounsfield Units] ± 22), (91 (391 156, p Conclusions This study demonstrates that, case diagnostic quality, permits an accurate identification measured reflect echogenity composition.
