Summary
The aim of this study was to determine the diagnostic accuracy of MR-FFR to detect functionally significant ICAS comparing with pressure-wire-based FFR.
Detailed description
This study will perform a head-to-head comparison between MR-FFR and pressure-wire-based FFR in patients with ICAS. Pressure-wire-based FFR will be used as the gold standard for intravascular pressure gradient measurement. The efficacy and safety of non-invasive FFR will be assessed in this study.
