Abstract: The present invention relates to multi-station scan. In order to improve selection of stations, a device is provided for detecting critical stations in a multi-station scan. The device comprises an input unit, a processing unit, and an output unit. The input unit is configured to receive image data taken from a patient lying on a table before start of a diagnostic scan with a magnetic resonance imaging system. The processing unit is configured to analyze the image data of the patient to identify a spatial location of the lungs of the patient to align the spatial location of the lungs of the patient with a planned multi-station scan to identify the critical stations that are potentially affected by a respiratory motion of the patient, and to assign breath-hold to the identified critical stations. The output unit is configured to provide the identified critical stations. Thus, the selection of critical stations can be automatically and consistently satisfied without operator intervention.

Abstract: A method of magnet resonance (MR) imaging of an object including: subjecting an object in an examination volume of an MR device to a dual echo steady state imaging sequence, a free induction decay signal (FID) and an echo signal (ECHO) being generated in each interval between two successive RF pulses, wherein a pair of diffusion gradient waveforms (GDIF) of equal phase integral and opposed polarity is applied in the interval between the FID signal and the echo signal; —acquiring the FID signals and the echo signals in a number of repetitions of the imaging sequence with varying phase encoding; and —reconstructing a diffusion weighted MR image from the acquired FID signals and echo signals.
