I can assure you (as an MRI radiographer) that no part of the MRI examination, including the potential use of Gd-DTPA contrast agents (and NSF or indeed any kind of adverse reaction), is EVER dismissed by the radiographer, radiologist or referrer. VERY strict processes are in place to protect patients and ensure that no risk is placed upon them. As was stated earlier, NSF has only been linked directly to certain gadolinium based MRI contrast agents (most central London hospitals no longer use) used in patients with poor renal function. Your doctor will advise you on whether there should be any concern over this in your case.
