摘要： An object to be MR imaged (10) is placed in an examination volume of a MR device (1). For faster MR imaging a multi-echo imaging technique which is robust with respect to motion is used. The method includes generating echo signals by subjecting the object (10) to an imaging sequence, acquiring the echo signals, each echo signal being attributed to a k-space line, wherein a number of k-space lines, which are adjacently arranged in a part of k-space, are repeatedly sampled, with said number of k-space lines being sampled in a different sequential order per repetition, and reconstructing a MR image from the acquired echo signals.

摘要： 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.
