MRI shows benefits of Mediterranean diet on the brain
By Wayne Forrest
The fabled Mediterranean diet may be good for your brain as well as your waistline. MRI has revealed that people who adhere to the diet have reduced brain white-matter hyperintensity volume, thus reducing their chance of chronic small-vessel damage, according to a study in the February issue of Archives of Neurology.

4D MRA progresses in cerebrovascular diseases
By Philip Ward
Time-resolved, or 4D, MR angiography (MRA) seems to be making rapid advances. The development of parallel-imaging techniques and hardware improvements such as gradient performance have enabled time-resolved MRA acquisition, which provides dynamic information at a feasible temporal resolution.
