We compared the diagnostic ability of FBI with that of CTA with using a calcification removal tool in the evaluation of the lower-extremity arteries with wall calcifications. In all segments, FBI provided diagnostic images regardless of the degree of wall calcification. On the contrary, CTA-MIP and CTA-MIP w/o Ca were strongly affected by calcification. The diagnostic ability of FBI was significantly superior to that of CTA-MIP and CTA-MIP w/o Ca in the moderate to severe calcified arterial segments. In conclusion, FBI is an accurate and noninvasive alternative to CTA for the assessment of aortoiliac and lower extremity arteries in patients with PAD.
