A segmented MR image is provided by measuring a number of Magnetic Resonance Imaging parameters on an absolute scale. For example T1 relaxation, T2 relaxation and Proton Density PD can be measured on an absolute scale. The absolute values are then compared with known values for at least one type of tissue. For human tissue these parameters typically are in the order 300-4500 ms for T1, 50-1000 ms for T2 and 0-100% water for PD. Both T1 and T2 depend on the field strength. Based on a comparison between normal values for a particular type of tissue the values obtained for the image each pixel/voxel can be labeled with a certain probability that the voxel contains this type of tissue and segmented accordingly.
