WebThe exercise-induced flow reserve (FR) was 167 +/- 90%. Conclusion: PC-MRI demonstrates that the resting triphasic flow waveform transforms into a monophasic pattern with submaximal exercise and returns to baseline with recovery. This increase in the regional blood flow allows for measurement of exercise-induced FR in the SFA.
