IVUS is significantly more sensitive than standard angiography for detecting coronary artery calcification, particularly for milder degrees of calcification.
Abstract
IVUS detected calcium in > 70% of lesions, significantly more often than standard angiography. Although angiography is moderately sensitive for the detection of extensive lesion calcium (sensitivity, 60% and 85% for three- and four-quadrant calcium, respectively), it is less sensitive for the presence of milder degrees.
