SYNTHETIC PARAMETER-WEIGTHED IMAGES BASED ON RELAXOMETRY (SPARE)

摘要

The present invention relates to a magnetic resonance (MR) imaging technique which provides high contrast images at low data acquisition times that is not limited to but especially advantageously applicable at high magnetic fields, thereby providing particularly high spatial resolution. The invention is implemented as a magnetic resonance imaging method as well as a respective device and a computer program product. The Magnetic resonance imaging method comprises providing a T 2 -map, which specifies for a plurality of voxels in a two-dimensional section of a target to be investigated a value T 2 of the magnetic resonance transverse relaxation time; deducing for each voxel a simulation time parameter value T 1* from the respective value T 2; providing a functional relationship S = S(T 1) between a magnetic resonance signal S that is expected to be measured for a predefined magnetic resonance pulse sequence and a value T 1 of the magnetic resonance longitudinal relaxation time at each voxel; calculating an imaging signal S* = S(T 1*), and outputting a two-dimensional image of the imaging signal S* = S(T 1*).
