Calcified lesions can cause blooming artifacts that hinder a reliable assessment of the vessel lumen.
Motion artifacts caused by non-optimal scan protocols and inferior imaging techniques may lead to an overestimation of the degree of stenosis. Thus, false positive findings may be introduced that can cause unnecessary further testing or treatment.
Siemens has continuously introduced a powerful set of product innovations designed to reduce false positives and boost specificity in cardiac imaging. As the two most important aspects in cardiac imaging are motion-free and sharp visualization of the coronaries, the solutions are designed to maximize both temporal and spatial resolution.
Recently, CT perfusion (CTP) has emerged as a promising method of gaining insight into the hemodynamic relevance of a stenosis. It has been shown that combining cCTA with CTP increases the specificity in detecting significant stenoses. To keep CTP as accurate as possible, Siemens has developed features to improve specificity in this aspect of cardiac imaging, as well.
