MR suite level designations: Don't let complex procedures overwhelm your facility
By Tobias Gilk
Over the past 20 years, the only MRI elements that have changed more than the equipment are the patients and the prescribed therapies they receive in the MRI suite. The fundamental shifts in the way the modality is used warrant a review of operations and the physical facilities through which care is delivered.

Gadolinium: A 'necessary factor' in the development of NSF?
By Sydney Schuster

The hundreds of people stricken with nephrogenic systemic fibrosis (NSF) -- allegedly after receiving the contrast medium for an MR exam -- might think so, not to mention the lawyers who are courting them. But how strong is the link between NSF and gadolinium chelates? While the scientific community untangles how this devastating disease became associated with a commonplace tool in the MR armamentarium, imaging professionals should be on guard.
