Diagnostic Accuracy for Hemodynamically ICAS of MR-FFR Comparing With Pressure-wire-based FFR.

Stroke, Ischemic Clinical Trial

Official title:
Diagnostic Accuracy for Hemodynamical Intracranial Atherosclerotic Diseases (ICAS) of Magnetic-Resonance-based Fractional Flow Reserve (MR-FFR) Comparing With Pressure-wire-based FFR.

Clinical Trial 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.

Clinical Trial 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. ;
