It's important because for the first time ever, one has been able to resolve chemical shifts with a single-sided apparatus," says Carlos A. The Stand-Up(TM) MRI demonstrated a low claustrophobic potential and yielded relatively high-resolution images with little motion, magnetic susceptibility, or chemical shift artifacts. Jinkins continued, "Mid-field MRI may be the optimal field strength for evaluation of degenerative disease of the spine because: Magnetic susceptibility artifact (directly related to field strength) is much reduced, Chemical shift artifact (also directly related to field strength) is much reduced, and Motion artifact is routinely much less than that experienced when using high-field units. |
