Validating Imaging Biomarkers of Small Vessel Disease in Diabetic Individuals Using Advanced MRI Techniques.

Completed

Conditions studied: Small Vessel Disease of Diabetes Mellitus

In brief

To develop a set of biomarkers for imaging of small vessel disease in diabetic individuals using advanced MRI techniques. With this the investigators want to document progression of disease both radiologically and clinically.
