3D MRI Can Spot Stroke Risk in Diabetic Patients

People with diabetes may be harbouring advanced vascular disease that could increase their risk of stroke, researchers warn.The findings suggest that arterial imaging with 3D MRI could be useful in helping to determine stroke risk among diabetics.
The carotid arteries are vessels on each side of the neck that supply oxygenated blood to the head.
Narrowing of the carotid arteries is associated with risk of stroke but less is known about stroke risk in people with little or no narrowing of these arteries.
For the new study, the team used 3D MRI to study the carotid arteries for evidence of intraplaque hemorrhage (IPH), an indicator of advanced atherosclerotic disease.
"A recent analysis has shown that people with carotid artery narrowing and IPH have a five- to six-times higher risk of stroke in the near future compared to people without," explained study author Tishan Maraj, imaging analyst at Sunnybrook Research Institute in Toronto.
