The Imaging Technique and Clinical Usefulness of Super Rapid Phase Contrast Angiography for Stroke Patients.

We offer super rapid phase contrast angiography (PCA) with a 60-second scan. This sequence greatly contributes to managing stroke patients compared with a conventional technique such as time-of-flight MRA. Parallel imaging and optimized voxel size reduce scan time as possible. Tilted optimized non-saturating excitation enhanced the depiction of the distal arteries in transverse acquisition PCA. Super rapid PCA overcomes motion artifacts due to short scan time and the shortest repetition time such as under 7 ms. Moreover, we obtain both MRA and black blood images as a subtraction image between the magnitude image and the MRA image.
