METHOD AND APPARATUS FOR ACCELERATED MAGNETIC RESONANCE IMAGING

摘要

In a method and apparatus for magnetic resonance (MR) imaging, a result image is provided based on multiple MR contrasts. The result image is indicative of a value of a magnetic parameter. MR data are acquired for the multiple contrasts at different time points, in each case following preparation of a magnetization. During the acquisition of the MR data, k-space is undersampled according to a respective undersampling scheme. The undersampling schemes of the different MR contrasts are different from one another.

1. A method for magnetic resonance (MR) imaging, comprising:
operating an MR scanner, while an examination subject is situated therein, to execute an MR data acquisition sequence wherein MR data are acquired from an examination region of the examination subject with a plurality of different MR contrasts at respectively different points in time, and entering the MR data for each MR contrast at k-space points in an electronic memory, representing k-space; in said MR data acquisition sequence, operating the MR scanner to prepare nuclear spins in the examination region prior to each acquisition of MR data for each of said MR contrasts; in said MR data acquisition sequence, operating the MR scanner to enter the MR data for each MR contrast at respective k-space points so that k-space is undersampled according to a respective undersampling scheme, with each undersampling scheme for each of said MR contrasts being different; from a computer, accessing said MR data from said electronic memory and calculating a result image from the MR data, said result image being comprised of pixels having respective pixel values that indicate a value of a magnetic parameter in said examination region; and making said result image available in electronic format an output of the computer as a data file.
