WebFeb 26, 2024 · As mentioned, arteries distal to significant stenosis will notbe triphasic. Figure 3. A normal color flow duplex ultrasound and triphasic waveforms at the common femoral artery (CFA) indicate normal aortoiliac flow since the aorta and iliac arteries are proximal to the CFA. Intra-stenosis waveforms 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.
