In a magnetic resonance a method and apparatus to generate images by a parallel acquisition technique, a first echo train is generated after a first excitation pulse, wherein the first echo train sufficiently densely scans a segment of k-space to be scanned for an acquisition of coil calibration data. Coil calibration data are acquired by means of the first echo train after the first excitation pulse. The acquired coil calibration data are stored in a coil calibration data set. A second echo train is generated after a second excitation pulse, wherein the second echo train undersamples a segment of k-space to be scanned for an acquisition of image data. Image data are acquired by means of the second echo train after the second excitation pulse. The acquired image data are stored in an incomplete image data set. An image data set is generated by substituting data missing in the incomplete image data set due to the undersampling by means of a selected PAT reconstruction technique using the coil calibration data. The first echo train and the second echo train are generated by an identical sequence technique such that each echo train has a series of echoes, with a time interval between successive echoes of the first echo train being shorter than a time interval of the second echo train.
