摘要： A method of differentiating tissues in Magnetic Resonance Imaging (MRI) comprising applying a Magnetization Transfer (MT) pre-pulse in combination with the Diffusion Weighted Imaging (DWI) pulse sequence to obtain an image of the tissue under evaluation. Analysis maps and/or measurements are generated from the obtained image, from which values representative of the macromolecular content are computed for obtaining tissue differentiation.

摘要： A method for adjusting a gain for reception of a magnetic resonance signal in a magnetic resonance imaging apparatus includes defining an initially set value of a slice thickness as slthick-original, defining a gain fit therefor as prescan-R1, and calculating a gain realtime-R1 fit for a changed value slthick-realtime of the slice thickness in accordance with: realtime-R1=(prescan-R1−(int)(log(slthick-realtime/slthick-original)+0.99)).
