METHOD AND APPARATUS FOR ACQUIRING MAGNETIC RESONANCE IMAGE DATA

摘要

In a method and apparatus for acquiring magnetic resonance image data, improved preparation of nuclear spins is achieved by radiating at least one inversion pulse, which acts site-selectively on at least one inversion pulse range, with the at least one inversion pulse range being situated at least partially outside the area under examination, radiation of at least one excitation pulse, read-out of magnetic resonance signals from the area under examination, and reconstruction of magnetic resonance image data from the read-out magnetic resonance signals, the magnetic resonance image data depicting the area under examination.

1. A method for generating a magnetic resonance (MR) image from an examination area of a subject, comprising:
operating a radio-frequency (RF) coil of an MR scanner, while an examination object is situated in the MR scanner, to radiate at least one inversion pulse that acts site-selectively on at least one inversion pulse range, said at least one inversion pulse range being situated at least partially outside of an examination area of the examination object; operating the RF coil of the MR scanner, while the examination object is situated in the MR scanner, to radiate at least one excitation pulse that causes MR signals to originate within said examination area; operating the MR scanner, while the examination object is situated therein, to read out said MR signals from said examination area; and providing said MR signals to a computer and, in said computer, reconstructing MR image data from the MR signals that were read out from said examination area, said MR image data depicting said examination area, and making said MR image data available from the computer in electronic form as a data file.
