MR pulsatility measurements in peripheral arteries: Preliminary results

Abstract: Phase contrast flow velocity measurements were performed in six healthy volunteers and 30 patients with arteriosclerotic disease. The iliac arteries were investigated in 8 cases and the femoral arteries in 28 cases. In the first 24 patients, 16 evenly distributed data sets were acquired during one cardiac cycle. In the last 12 patients, a trigger pulse followed by the acquisition of 30 evenly distributed data sets was applied every second heart beat. This procedure allowed data to be acquired over a full heart… Show more

“…We found an increasing proportion of qualitatively and quantitatively assessed abnormal femoral waveforms with increasing degree of iliac artery stenosis. The use of MRI-derived flow velocity profiles for the assessment of iliac artery stenoses has, to our knowledge, only previously been reported by MOHIADDIN et al (14) and KRUG et al (8). MOHIADDIN et al (14) observed a flattened curve profile in the iliac artery distal to common iliac artery stenoses compared with flow profiles in healthy volunteers.…”

“…In that study, however, there was no attempt to further analyze the effect of varying degrees of stenosis on the flow velocity curve. KRUG et al (8) found an inverse correlation between systolic acceleration and the degree of proximal stenosis. Their study was limited by the small number of iliac arteries (n58) investigated.…”

“…Although phase contrast imaging was originally used to obtain MRA images (160–163), some authors have used the quantitative information inherent in MR phase contrast scans to derive information on the severity of PAOD. Similar to Doppler ultrasound, the waveforms derived in locations superior or inferior to stenoses or simply in two locations on the proximal and distal leg can be used to characterize the severity of PAOD (164, 165). Changes from normal triphasic waveforms upstream of a stenosis to monophasic waveforms downstream of a stenosis are typical for high‐grade stenosis (166, 167).…”

“…However, the diversity of MR is useful for the assessment of all aspects of atherosclerosis. For example, spectroscopic evaluation can assess lipid content (9, 10) and phase contrast techniques can be used to study the hemodynamic effects of atherosclerotic lesions (11). Finally, as a result of the development of several MR techniques for in vivo measurement of vessel compliance (12) and pulsewave velocity (13–16), the mechanical properties of the vascular wall can be interrogated as well.…”
