- UHR PCCTA significantly improved the assessment of calcified coronary stenoses by reducing calcium blooming artifacts, resulting in more accurate stenosis quantification than standard-resolution CCTA.
- Compared with standard-resolution imaging, UHR PCCTA reclassified 54.4% of patients to a lower CAD-RADS category, with fewer recommendations for downstream functional testing and invasive coronary angiography.
- The findings support PCCT as an important advance for evaluating patients with suspected or known coronary artery disease, particularly in the presence of coronary calcification where conventional CCTA has limited specificity.
