Noninvasive assessment of fractional flow reserve according to coronary computed tomography angiography using hydrodynamic calculations
Purpose. Testing and verification of the methodology for non-invasive determination of the Fractional Flow Reserve (FFR) based on coronary Computed Tomography An-giography (CTA). Results. Hydrodynamic calculation of blood flow in the coronary artery makes it pos-sible to estimate FFR with a deviation from invasively measured values less than 7%. Conclusion. The scientific and clinical potential of the proposed methodology for the non-invasive determination of FFR by the results of CTA to assess the significance of steno-sis in the coronary arteries has been demonstrated. © 2020 Russian Electronic Journal of Radiology.
