Helical MR: continuously moving table axial imaging with radial acquisitions.
A technique for extended field of view MRI is presented. Similar to helical computed tomography, the method utilizes a continuously moving patient table, a 2D axial slice that remains fixed relative to the MRI magnet, and a radial k-space trajectory. A fully refocused SSFP acquisition enables spatial resolution comparable to current clinical protocols in scan times that are sufficiently short t...
متن کاملRespiratory-Gated Continuously Moving Table 3D MRI
B. Aldefeld, P. Börnert, J. Keupp, K. Nehrke Philips Research Laboratories, Hamburg, Germany Introduction When continuously moving table imaging is applied to an extended virtual FOV that includes the abdomen and chest, the physiological motion of the patient must be addressed to achieve optimum image quality. Scanning under breath-hold conditions is unacceptable in most cases because scan time...

H. H. Hu, A. J. Madhuranthakam, D. G. Kruger, J. F. Glockner, S. J. Riederer MRI Research Lab and Department of Radiology, Mayo Clinic College of Medicine, Rochester, Minnesota, United States Introduction: SENSE is a parallel imaging method [1] that has been used to provide reduction in acquisition time or improvement in spatial resolution in a variety of clinical applications. The basis for SE...

D. G. Kruger, S. J. Riederer, J. F. Glockner, J. A. Polzin, A. J. Madhuranthakam, H. H. Hu Mayo Clinic, Rochester, MN, United States, GE Medical, Milwaukee, WI, United States Synopsis: Recently a technique has been described in which an image is formed of an extended object while it is moved continuously through the bore of the MR magnet. This initial work described the image formation process,...
متن کاملTwo Approaches to Water/Fat Selective Whole-Body Continuously Moving Table 3D Imaging
P. Börnert, B. Aldefeld, J. Keupp, H. Eggers Philips Research Laboratories, Hamburg, Germany Introduction Non-invasive measurement of the fat distribution using MRI may be of interest for future whole-body screening procedures. For example, the perilesional fat sparing can serve as an indicator for tumors or their metastases. Furthermore, the amount of body fat and its local bio-distribution sh...
