Studies outline techniques for ramping up MR in renal artery imaging
By Shalmali Pal
Nephrogenic systemic fibrosis (NSF) continues to puzzle the MR imaging community, but patients with renal disorders must still undergo imaging exams and MRI remains the best option for detecting and grading kidney disease. Two recent studies offer advanced techniques for MR angiography (MRA) and MRI in the renal arteries. In both cases, gadolinium-based agents were used successfully without any serious side effects. AuntMinnie.com takes a look at the studies and discusses the role of gadolinium-enhanced MRA in this patient population with the authors.

Gadolinium release linked to overall stability of contrast agent, may trigger NSF
By Shalmali Pal
German researchers believe they have found a qualitative correlation between nephrogenic systemic fibrosis (NSF)-like symptoms and the release of free gadolinium in an experimental study. In this animal model, a multiple-injection scheme was used to replicate the prolonged systemic exposure to contrast media that is experienced after repeated gadolinium administration in patients with severe renal impairment.

AJR study: Women more likely to have gadolinium reactions, but acute cases remain mostly mild
By Shalmali Pal
Female patients are more likely to experience reactions to gadolinium-based contrast agents, especially as adults, according to a new study. Although the majority of these reactions are quite mild, clinicians who perform contrast-enhanced MR studies should be prepared to manage them, stated the authors.

Open MRI reduces patient claustrophobia, study confirms
By Kate Madden Yee
MRI offers powerful diagnostic information for various diseases and conditions -- if the patient doesn't experience claustrophobia and can relax enough to allow the scan to be performed. Researchers from Germany conducted a study evaluating how much patient claustrophobia was reduced by using MRI scanners with acoustic noise reduction and an open magnetic bore versus conventional scanners.
