Abstract: An object (10) is placed in an examination volume of a MR device (1) and imaged using a multi-echo imaging technique which is robust with respect to motion. The imaging includes subjecting the object (10) to a number of shots of a multi-echo imaging sequence to generate a train of echo signals by each shot and acquiring the echo signals. Each echo signal represents a k-space profile, wherein k-space (20) is divided into a central k-space part (21) and one or more peripheral k-space parts (22, 23). The central k-space part (21) is sampled by a single shot of the multi-echo imaging sequence, and the peripheral k-space parts (22, 23) are sampled by one or more further shots (25, 28) of the multi-echo sequence; and an MR image is reconstructed from the k-space profiles.

Abstract: A device for alternating examination of a measurement object (170) by means of MPI and MRI with two magnetic field-generating elements is presented. The device is characterized by a main magnet coil system with two coaxial partial coil systems (100a1, 100a2; 100b2, 100b1) arranged mirror-symmetrically relative to a central plane running perpendicularly to the z-axis through the first volume under investigation (162). The volumes under investigation are superimposed. A polarity reversal device (190) reverses the polarity of the current through a partial coil system and the main magnet coil system generates a homogeneous magnetic field of at least sixth order in the first volume under investigation when the partial coil systems have identical polarity, and a spatially strongly varying magnetic field profile in the second volume under investigation when the polarities are opposite. Repositioning of the measurement object is thereby simplified or can even be eliminated.
