In a magnetic resonance method and system for automatic generation of a selective MR image from a first MR image (corresponding to raw data acquired at a first echo time after excitation pulses) and a second MR image (corresponding to raw data acquired at a second echo time after the same excitation pulses), for each image point of the MR images, a time constant is calculated for tissue to be imaged at the respective image point depending on the intensity values of the corresponding image points of the first and second MR images. The calculated time constant is compared with at least one threshold in order to associate a weighting factor with that image point. The selective MR image is generated by processing the intensity values of the image points of the first and/or second MR image with the associated weighting factors.
