Conclusion

Peripheral arterial disease (PAD) is a world-wide problem affecting predominantly elderly patients [Aronow], who has known, have a progressive decrease in arterial blood flow [Masugata].

 

Because of fast scanning allowed by the current 64-slice and higher MDCT devices the exact assessment of the delay needed by the contrast media to reach the feet is critical to correctly plan and acquire MDCTA of PAD.

 

Our MDCTA technique in PAD is feasible in routine and emergency allowing optimal assessment of wall irregularities, stenosis/obstruction and any collateral vessels.

 

Calculating the true scan delay tailored to each patient with a bolus test at the ankle level is in our opinion mandatory to optimize MDCTA in patients with PAD.
