Conventional contrast-enhanced peripheral MR angiography
(MRA) typically uses subtraction-based methods, which
are susceptible to misregistration from patient motion
and suffer from decreased signal-to-noise ratio (SNR)
relative to non-subtractive methods. Previous work has
demonstrated the use of non-subtractive
contrast-enhanced peripheral MRA at 3.0 T during the
steady state and at 1.5 T using a bolus-chase method.
This work investigates the clinical feasibility of using
a contrast-enhanced, time-resolved, non-subtractive
method for MRA at 3.0 T in patients with peripheral
vascular disease.
