TEMPORALLY RESOLVED 3D PHASE-CONTRAST IMAGING

A conventional 3D phase contrast acquisition generates images with goo d spatial resolution, but often gives rise to artifacts due to pulsati le flow. 2D cine phase contrast, on the other hand, can register dynam ic flow, but has a poor spatial resolution perpendicular to the imagin g plane. A combination of both high spatial and temporal resolution ma y be advantageous in some cases, both in quantitative flow measurement s and in MR angiography. The described 3D cine phase contrast pulse se quence creates a temporally resolved series of 3D data sets with veloc ity encoded data.
