Fresh blood imaging (FBI) is a novel non-contrast enhanced three-dimensional MR angiography technique. In this study, we compared FBI with CT angiography in the evaluation of peripheral arterial disease. Sensitivity, Specificity, and accuracy of FBI with regard to detection of 50% or greater luminal reduction were 97%, 98`%, and 97%, respectively. FBI is an accurate and noninvasive alternative to CT angiography for the assessment of aortoiliac and lower extremity arteries in patients with peripheral arterial diseases.
