UHR PCCTA reduced unnecessary downstream testing compared with conventional energy-integrating detector (EID) CCTA, including an 18.9% reduction in functional follow-up tests and a 6.0% reduction in invasive coronary angiography (ICA).
Improved diagnostic specificity with PCCT translated into a 9.4% reduction in procedure-related complications for patients with stable chest pain and coronary calcification.
Health-economic modeling projected that implementing UHR PCCTA could save approximately USD 795 per patient, corresponding to nearly USD 12 million in healthcare cost savings over the expected 10-year lifetime of the CT system.
