2D MR-DSAにおける画質向上の検討

概要

Enhanced MRA using the three-dimensional Fourier transform (3DFT) sequence for the body or its extremities is commonly adopted. Through advanced technology in the areas of turbo-MRA and ZIP(zerofilled interpolation) high-quality imaging as well as progress in spatial resolution, the anatomy of blood vessels can be depicted with the same high quality as that provided by DSA (digital subtraction angiography). In spite of these technological advances, it is still difficult to obtain clear delineation of the arteriovenous phase and hemodynamics because of the 7-30 second acquisition time. In this study, we examined the possibility of shortening the time to provide effective temporal resolution in the clinical setting. MR-DSA is useful for clinical application because high-quality images with good spatial resolution can be obtained with the 2DFT sequence.
