Stanford researchers have designed a system to provide accelerated magnetic resonance imaging (MRI) in the presence of metallic implants, which induce variations in the static magnetic field that normally require long scan times.
MR-guidance for biopsy procedures features high intrinsic soft-tissue contrast. However, artifacts induced by the metallic needle such as signal void and distortions can reduce the localization of the needle and thus prevent the targeting of smaller lesions.
Homodyne image reconstruction is combined with an iterative decomposition of water and fat from MR signals obtained from a partial k-space signal acquisition in order to maximize the resolution of calculated water and fat images.
Disclosed is a wideband SSFP, wherein a standard balanced SSFP MRI sequence is played with repetition times of alternating lengths, TR and TR.sub.s, where TR.sub.s
A magnetic resonance imaging system or method is provided including a balanced steady-state free-precession transient imaging (transient bSSFP) device capable of increasing the overall signal during transient bSSFP acquisition by fully or better utilization of the magnetizatio
