Talk Title: Contrast Enhanced MR Angiography, Recent Improvements in Resolution, Application, and Coverage
Abstract: Although MR Angiography (MRA) has been under study for well over two decades, the field still continues to advance. The technical innovations of parallel data acquisition, specific k-space data sampling methods, and high-count receiver coil arrays can be integrated to allow marked reductions in the acquisition times necessary to form high quality 3D MR angiograms with comparable or even improved spatial resolution compared to a decade ago. If implemented with appropriately designed receiver coil arrays, the loss of SNR can be carefully controlled. Advanced k-space sampling methods reduce the sensitivity of the reconstructed images to temporal blurring and allow time-resolved results which can readily distinguish arterial from venous phases in problematic cases. Further extensions permit high quality, multi-station imaging of the peripheral vasculature. In this presentation these methods will be described, and in vivo results from multiple vascular territories will be presented.
