What is Continuously moving table 3D MRI with lateral frequency-encoding direction about?

## Abstract A method is presented for 3D MRI in an extended field of view (FOV) based on continuous motion of the patient table and an efficient acquisition scheme. A gradient‐echo MR pulse sequence is applied with lateral (left–right (L/R)) frequency‐encoding direction and slab selection along the direction of motion. Compensation for the table motion is achieved by a combination of slab tracking and data alignment in hybrid space. The method allows fast __k__‐space coverage to be achieved, especially when a short sampling FOV is chosen along the direction of table motion, as is desirable for good image quality. The method can be incorporated into different acquisitions schemes, including segmented __k__‐space scanning, which allows for contrast variation with the use of magnetization preparation. Head‐to‐toe images of volunteers were obtained with good quality using 3D spoiled gradient‐echo sequences. As an example of magnetization‐prepared imaging, fat/water separated images were acquired using chemical shift selective (CHESS) presaturation pulses. Magn Reson Med, 2006. © 2006 Wiley‐Liss, Inc.
