Abstract
A magnetic resonance tomography (MRT) method with spectral fat saturation or spectral water excitation in a tissue region that is to be represented of a patient who is to be examined, includes the following steps: (Step 1) frequency adjustment measurement of a region of a patient that is to be represented with a selected first partial coil of the MRT system, (Step 2) precise determination of the resonance frequency of water with the aid of the spectrum obtained in Step 1 exhibiting the resonance frequencies of fat and water, (Step 3) repetition of Steps 1 and 2 with at least one additionally selected second partial coil of the MRT system adjacent to the first partial coil, (Step 4) measuring of a k space data record with a partial coil or a partial coil combination on the basis of the water resonance frequency assigned to these partial coils, (Step 5) repetition of Step 4 with other partial coils or other partial coil combinations until the entire tissue region to be represented has been measured, (Step 6) combining of the measuring results obtained in Steps 4 and 5, and (Step 7) representing of the results obtained in Step 6 in the image space in the form of an overall image of th…
