摘要： A method of magnetic resonance spectroscopic imaging of an object (O) including at least one chemical species to be imaged, comprising sampling of the k-space such that a plurality of Nω first sampling trajectories through at least one k-space segment of the k-space is formed along a phase-encoding direction, each of said first sampling trajectories beginning in a central k-space region and continuing to a k-space border of the at least one k-space segment and having a duration equal to or below a spectral dwell time corresponding to the reciprocal spectral bandwidth, collecting at least one first set of gradient-echo signals obtained along said first sampling trajectories, collecting at least one second set of gradient-echo signals obtained along a plurality of Nω second sampling trajectories, said Nω second sampling trajectories and said Nω first sampling trajectories being mutually mirrored relative to a predetermined k-space line in the central k-space region.

摘要： The invention relates to an HF-antenna system for carrying out and/or detecting a magnetic resonance in an object exposed to a main magnetic field which orients the object spins in a desired longitudinal direction (z) comprising at least one first antenna element (1) provided with several conducting sections (11, 12, 13, 14) which lead a high-frequency alternating current and extend from the common top to a base area in the form of separate claws in such a way that the testable object containing a volume of interest is enveloped in a helmet manner. Said invention is characterized in that each conducting section (11, 12, 13, 14) is embodied in the form of a HF (HL) line for electromagnetically connecting a wave propagating in a TEM mode or in an quasi-TEM mode with the spins of the testable object to be enveloped and the electrical length the terminals of the HF (HL) lines are selected in such a way that the magnetic resonance frequency waves are produced therein.
