The contrast medium expansion type magnetic resonance blood vessel contrast method which accompanies blood vessel segmentation

摘要

(57) Abstract The magnetic resonance blood vessel contrast figure (RMA) is acquired making use of the contrast expansion method where time of said inspection where the contrast medium bolus first passes the artery and the vein series the resolution NMR picture is acquired low quickly in disassembly phase. Furthermore, with steady state phase of the said inspection which follows to that the high resolution NMR graphics data is acquired, the high resolution NMR picture is reconstructed from this data. The said making use of the information of the resolution NMR picture low, segmentation of the artery, the vein, and the background in the said high resolution picture is executed.
