Comparative Study
Optimization of contrast-enhanced peripheral MR angiography with mid-femoral venous compression (VENCO).
To compare a standard protocol for contrast-enhanced three-dimensional magnetic resonance angiography (3D CE-MRA) of the lower extremities to a high spatial resolution protocol with venous compression (VENCO) at the mid-femoral level. ⋯ VENCO 3D CE-MRA is simple to put into practice and advances the performance of multi-station MRA strategies for assessment of the peripheral arterial vasculature.

Comparative Study
High spatial resolution whole-body MR angiography featuring parallel imaging: initial experience.
To combine whole-body multi-station three-dimensional contrast enhanced magnetic resonance angiography (3D CE MRA) using a self-developed rolling table platform with parallel imaging strategies (PAT) in order to increase the spatial resolution of the 3D MRA data sets. ⋯ The implementation of PAT into the concept of whole-body MRA enabled to increase the spatial resolution in all examined territories, which resulted in more detailed MR angiograms.
