Abstract: In a method and apparatus for acquiring and reconstructing a four-dimensional dynamic magnetic resonance (MR) image data record, MR data are continuously acquired by radial scanning of an examination region along radial k-space lines, and a dynamic region of the examination region, in which said dynamic procedure is relevant, is determined, as well as a non-dynamic region, which is not relevant to the dynamic procedure. Static image data are reconstructed from all of the acquired MR data, and image data therein originating from the non-dynamic region are marked and are then not used for reconstructing a dynamic image data record for the dynamic region.

Abstract: For reduction of artifacts when acquiring magnetic resonance (MR) data using an MR apparatus, a SPAR pulse, which acts on spins in a first predetermined frequency range, and a saturation pulse, which acts on spins in a second predetermined frequency range, are radiated. A gradient for spatial encoding is activated at the same time as the saturation pulse, so that the saturation pulse acts on an edge region adjacent to the volume segment. The edge region borders an ellipsoidal useful volume of the scanner of the MR apparatus, in which the strength of the B0 field changes in terms of magnitude by no more than 30 ppm. Spoiler gradients are activated to destroy a transverse magnetization, before an RF excitation pulse, adjusted to the SPAIR pulse, is radiated. MR data are acquired after the SPAIR pulse, the saturation pulse and the RF excitation pulse. The second frequency range is adjusted to the first frequency range.

Abstract: In a magnetic resonance apparatus and an operating method therefore, a data acquisition sequence for operating the apparatus is repeatedly reviewed in a number of ascertainment passes executed in a processor, each ascertainment pass involving a calculation step, and in each calculation step a determination is made as to other respective values of data elements used in a previous calculation step have changed. If no change has occurred, a re-calculation in the current calculation step is not implemented, thereby reducing the time and computing capacity that are needed to generate a final data acquisition sequence.

Abstract: A method is disclosed for creating a motion correction for PET data acquired by a PET system from a volume segment of an examination object. The method includes acquisition of MR data within the volume segment by the magnetic resonance system; and determination of a motion model of a motion within the volume segment as a function of the MR data. The motion model, as a function of a respective motion state of the motion, provides a correction specification for PET data which is acquired during this motion state. During acquisition of the MR data, specific MR data is acquired in the center of the k-space or of a straight-line segment which passes through the center of the k-space. The MR data determined is converted by a mathematical function into one value, as a function of which the respective motion state is determined.
