Participants underwent an MRI exam at the beginning of the study, and again two years later. Researchers also then tested the participants’ memory using several scales. From the memory tests, researchers identified 25 participants (17 percent) whose memory declined during the two years, and 124 participants who did not.

Open design, wide bore, noise reduction MRI machines can ease claustrophobia. Do patients prefer them; are they cost effective; do they improve image quality?

On February 8, 2011, a new cardiac pacemaker received approval from the FDA, which for the first time allows MRI procedures to be performed in patients by following specific labeling requirements. http://www.medtronic.com/mrisurescan. The “MR Conditional” Revo MRI SureScan Pacing System from Minneapolis-based Medtronic Inc. was designed to minimize the potential interactions with the electromagnetic fields used during MRI examinations.

MRI could help detect Alzheimer’s disease at an early stage - before irreversible damage has been done, according to the second recent study to examine MRI use for Alzheimer’s.

Using MRI may help researchers predict which adults are likely to develop Alzheimer’s disease, according to a new study published online and in the June issue of Radiology.

Five years after the first reports linking gadolinium-based MRI contrast agents to nephrogenic system fibrosis (NSF), separate presentations of post-marketing data from manufacturers and an independent prospective study supported by agencies in France have validated the low-risk status of the contrast agent Dotarem (Gd-DOTA).

Stroke in young adults is one of the leading causes of disability, and the third leading cause of death, according to the American Stroke Association. Yet with an early MRI scan and the right treatment, the effects from strokes can be can be completely reversed.
