The researchers & # 39; Sherbrooke documented First Arterial and Veinous Atlas of Human Brain

Kevin Whittingstall, Professor & # 39; research in the faculty of medicine and the health sciences (FMSS) University de Sherbrooke and in the Center & # 39; Research & # 39; Chus, devoted years to develop & # 39; non-invasive imaging to see the structure and functioning of the human brain techniques. Student & # 39; his doctorate, Michaël Bernier, who is now a postdoctoral partner – Medical School & # 39; Harvard, Developed tool & # 39; & # 39 software; groundbreaking segmentation. Together, they could remove image & # 39; blood vessels in the brain that are usually difficult to see using & # 39; noninvasive procedures. Thanks to these images, are documented arterial and venous atlas of the most complete of the human mind world. Stephen Cunnane, professor and researcher at the Center of FMSS and & # 39; research organizations, has also collaborated in & # 39; this discovery.

The atlas mind: like fingerprint databank & # 39;

"We are spending 10 minutes at & # 39; & # 39 session, magnetic resonance imaging (MRI) to take two images of the patient's brain", explained Kevin Whittingstall. "The first imaging target arteries by measuring blood velocity. The second image measuring magnetic interference, to b & # 39; so they can see the veins. Our images are so precise that enable to quantify the structure, length and diameter of & # 39; each brain region Michaël then collect them using software that combines mathematics with & # 39; processing & # 39; the image before arterjovenu obtain a tree that is unique to each patient. "

The atlas of the brain can & # 39; & # 39 thus comparable; fingerprint databank & # 39 ;. The team can & # 39; comparing the vascular tree with the patient & # 39; minds with images taken from & # 39; health and determine whether there are subtle variations. If so, the team will try to determine where they originated. They are a brain concussion or early disease & # 39; Alzheimer's, and so on?

F & # 39; November still this innovation made the page & # 39; in front of the Human Brain Maps. The team is already being sought by researchers at & # 39; other countries who want to use the atlas in clinical studies on brain concussion and stroke (cerebrovascular accident).
