MOTION CORRECTED SIMULTANEOUSLY ACQUIRED MULTIPLE CONTRAST CORONARY MRI SYSTEMS AND METHODS

摘要

In various embodiments, the present application discloses systems and methods for magnetic resonance imaging (MRI) of coronary arteries. In various embodiments, the invention allows for motion corrected, simultaneously acquired multiple contrast weighted images with whole-heart coverage and isotropic high resolution. In some embodiments, the invention teaches using interleaved preparatory pulses, a 3D radial golden angle trajectory and 100% respiratory gating efficiency.

主权项

1. A method for performing magnetic resonance imaging (MRI), comprising:
(a) positioning an object in a magnetic field; (b) using a radio frequency (RF) coil to apply one or more preparatory pulses during each of one or more repetition periods, wherein one or more of said preparatory pulses selectively suppresses the signal of one or more components of the object, based on different relaxation times of two or more components of the object; (c) applying readout pulses to the object; (d) acquiring imaging data in an interleaved fashion for different sets of images of the object during repetitions, wherein each set of images has a different contrast weighting; and (e) overlaying and color-coding images with different contrast weightings.
