Non-invasive CT FFR technique with AI
Diagnostic Value of Non-invasive Functional Assessment of Coronary Arteries
Fractional flow reserve (FFR), which measures the blood flow reduction caused by vessel narrowing, is accepted as the reference standard for assessing the functional significance of the stenotic lesions 1. Multiple randomized trials have demonstrated that FFR has excellent diagnostic value in identifying functional significant lesions and guiding coronary revascularization procedures. However, FFR is measured invasively through a guide wire-based cardiac catheter procedure in the catheterization lab. It is not suitable for myocardial ischemia screening in stable patients with CAD. Current guidelines recommend assessing myocardial ischemia of stable patients with CAD through non-invasive functional testing before considering invasive coronary angiography (ICA) or conducting myocardial revascularization 1,2.
