Abstract
The purpose of this study was to evaluate a variable k-space sampling metho d for bolus-chase three-dimensional magnetic resonance digital subtraction angiography in the arterial system from the abdomen to the calf. Imaging ti me was minimized by tailoring the acquisition according to the vascular ana tomy of the station. For images obtained in 30 patients, results with the m odified protocol were compared to those with the previously published proto col. For all stations, significant improvement (P <.001) was found with the modified protocol.
