NCT00707876

Brief Summary

The purpose of this study is to compare the difference between two magnetic resonance imaging (MRI) techniques for visualizing arteries. The study hypothesizes that one method that relies upon imaging flowing blood in the pelvic and leg arteries will not be as accurate or efficient as injecting a safe imaging agent to change the appearance of the blood on the MRI. Both methods will be compared with Digital Subtraction Angiography (DSA).

Outcome Measures

Primary Outcomes (2)

  • Segment-level Sensitivity and Specificity of VE-MRI at 3 Ferumoxytol Dosing Levels and Differences in Sensitivity and Specificity by Dose Group

    Analysis of the sensitivity and specificity of VE-MRI by dose group was performed on the ITD segments by 3 Readers. The per reader comparison of VE-MRI sensitivity and noncontrast MRA sensitivity will take into account that readings are correlated because each subject (and segments) undergo both VE-MRI and noncontrast MRA scans. The differences between ferumoxytol dose groups for the difference between VE-MRI and noncontrast MRA will be reported. The data were pooled across all imaging platforms.

    3 weeks

  • Segment-level Sensitivity and Specificity of Noncontrast MRA at 3 Ferumoxytol Dosing Levels and Difference From Sensitivity by Dose Group

    Analysis of the sensitivity and specificity of noncontrast MRA by dose group was performed on the ITD segments by 3 Readers. The per reader comparison of VE-MRI sensitivity and noncontrast MRA sensitivity will take into account that readings are correlated because each subject (and segments) undergo both VE-MRI and noncontrast MRA scans. The differences between ferumoxytol dose groups for the difference between VE-MRI and noncontrast MRA will be reported. The data were pooled across all imaging platforms. The data were pooled across all imaging platforms.
