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.
