acquiring the echo signals, wherein each echo signal represents a k-space profile, wherein k-space is divided into a central k-space part and one or more peripheral k-space parts, wherein the central k-space part is sampled by a single shot of the multi-echo imaging sequence, and wherein the peripheral k-space parts are sampled by one or more further shots of the multi-echo sequence,
wherein sampling of the peripheral k-space parts starts at a position in k-space where the sampling of the central k-space part starts and/or the sampling of the peripheral k-space parts ends at a position in k-space where the sampling of the central k-space part ends,
wherein the k-space profiles acquired from adjacent positions in k-space have adjacent or identical echo index numbers, the echo index number indicating the position of each echo signal within the train of echo signals generated by each shot of the multi-echo imaging sequence, and
reconstructing a MR image from the k-space profiles.

METHOD AND APPARATUS FOR MULTI-SLICE IMAGING OF T2-RELAXATION TIME

BETH ISRAEL DEACONESS MED...

1. A magnetic resonance imaging (MRI) method comprising:performing a first image acquisition module of a pulse sequence to acquire a first MR data from slices disposed at different locations in a region of interest (ROI) of an object, by applying, to each of the slices, a slice-selective magnetization preparation module and an imaging module, the slice-selective magnetization preparation module being executed with a first T2 preparation time having a first time echo;
performing a second image acquisition module of the pulse sequence, to acquire a second MR data from the slices disposed at the different locations of the ROI, by applying, to each of the slices, the slice-selective magnetization preparation module and the imaging module, the slice-selective magnetization preparation module being executed with a second T2 preparation time having a second time echo different from the first time echo;
generating a T2 map based on the first MR data and the second MR data; and
displaying the T2 map as a viewable medical image of the ROI.

a resistive MRI gradient coil system;
a main magnet coil system disposed around a z axis, said main magnet coil system having two coaxial partial coil systems that are arranged mirror-symmetrically with respect to a central plane running perpendicularly to the z axis through a first volume under investigation, said main magnet coil system generating a homogeneous field of at least 0.5 T and of at least 6th order for MRI operation within said first volume under investigation and a spatially strongly varying magnetic field profile for MPI operation within a second volume under investigation, wherein said first and said second volumes under investigation at least partially overlap, said spatially strongly varying magnetic field profile having field vectors which are different with respect to direction or magnitude at all spatial points and having a field magnitude zero at one spatial point;
a device for reversing a polarity of current through one of said partial coil systems, wherein said main magnet coil system is designed in such a fashion that it generates said homogeneous magnetic field in said first volume under investigation when polarities of said partial coil systems are the same and said spatially strongly varying magnetic field profile in said second volume under investigation when said polarities are opposite; and
a linearly controlled power supply, said linearly controlled power supply supplying a direct current to said partial coil systems, wherein said direct current is held stable to ppm during MRI operation.
