A serial in vivo 7T magnetic resonance phase imaging study of white matter lesions in multiple sclerosis.

The article offers information on a research that analyzes the effect of 7T magnetic resonance imaging technique in the diagnosis of multiple sclerosis (MS). It is mentioned that five patients with MS were serially scanned for around 2.5 years at 7T using high resolution gradient-echo sequence. It was observed that ring phase lesions remained unchanged over 2.5 years which contrasts the notion that acute activated iron-rich macrophages reside in such lesions.
