Diagnostic accuracy of nonenhanced Fresh Blood Imaging (FBI) was compared with digital subtraction angiography (DSA) or digital angiography (DA), which was performed at percutaneous transluminal angioplasty (PTA), in the evaluation of the peripheral lower-extremity arteries. In the evaluation of 173 segments in 25 patients with peripheral arterial occlusive disease, the sensitivity, specificity, and accuracy of FBI of a consensus reading for detection of 50% or greater stenotic lesions were 100%, 83%, and 88%, respectively. FBI achieves high diagnostic accuracy for the detection of peripheral arterial disease (PAD) in comparison with DSA.
