HEART THORAX. AI-assisted coronary CT angiography beats perfusion imaging

In patients with stable chest symptoms, significant coronary stenoses must be reliably excluded. The method of choice has been myocardial stress perfusion imaging (MPI), but this has limited performance for ischemia detection and therefore too often follows invasive coronary angiography (ICA). Many guidelines recommend non-invasive CT angiography (CTA), which detects obstruction with high accuracy, and acts as a gatekeeper to reduce ICA. The study group compared the diagnostic performance of MPI and AI-QCT, which uses artificial intelligence for quantitative analysis of the coronaries.
