Patient-Specific Models May Predict Brain Aneurysms

Learn how Purdue Engineers use medical imaging technology to build patient-specific models of aneurysms to help doctors predict areas of danger.

“Aneurysms present a difficult issue for doctors,” said Vitaliy Rayz , associate professor of biomedical and mechanical engineering. “Patients often aren’t symptomatic, so many don’t even know they have them. Cerebral aneurysms are often incidentally detected during imaging exams, such as CT [computed tomography] and MRI [magnetic resonance imaging]. The real question is: how can we determine when an aneurysm will remain unchanged, or is likely to enlarge and needs to be treated to prevent a rupture?”
