Magnetic resonance angiography with vessel segmentation

, : Magnetic resonance angiography with vessel segmentation. Official Gazette of the United States Patent & Trademark Office Patents 1257(5), Apr 30

A magnetic resonance angiogram (MRA) is acquired using a contrast enhancement method in which a series of low resolution NMR images are rapidly acquired during a time resolved phase of the examination in which the contrast bolus makes a first pass through the arteries and veins. Additional, high resolution NMR image data is acquired in a subsequent steady-state phase of the examination from which a high resolution NMR image is reconstructed. Segmentation of arteries, veins and background in the high resolution image is performed using information in the low resolution NMR images.
