OBJECTIVE: To investigate the correlation between the hemodynamic parameter ankle-brachial pressure index (ABI) and the run-off resistance (ROR) assessed on MR angiograms (MRA) in patients with peripheral arterial disease (PAD) Fontaine Stage I and II and its potential as reliable reporting system in clinical routine. METHODS: Contrast-enhanced MRA was performed in 321 PAD patients using a 1.5T MR scanner with moving bed technique. The ROR and resting ABI were determined in each patient's leg and correlation analysis was performed using the Pearson test. RESULTS: A significant negative correlation (r=-.513; p<.001) between ROR (mean 11.03±5.42) and resting ABI (mean .81±.26) was identified. An even more pronounced correlation was found in patients younger than median age who had higher ABI values (r=-.608; p<.001). CONCLUSION: The ROR scoring system evaluated in this series correlates better with the ABI than previously published scoring systems and could be suggested as reporting system for routine MRA evaluation. |
