Taking the Guesswork Out of Aneurysms


A collaboration between University of Minnesota radiologists and engineers is helping health professionals better understand how aneurysms work.

With support from the Wallin Neuroscience Discovery Fund, Dr. Bharathi Jagadeesan is partnering with colleagues in neurosurgery, aerospace engineering, and the Center for Magnetic Resonance Research (CMRR) to better understand why and when aneurysms rupture.

The group's research involves using high-powered 7 Tesla MRI machine at the CMRR to scan patients’ aneurysms. They then 3D-print the high-resolution scans and test them using engineering instruments.

“We want to be able to say to a patient, ‘Your aneurysm looks similar to those that have remained stable for years, so let’s stay put for now,’" said Dr. Jagadeesan in an interview. “Or we’ll have the evidence to say, ‘The pattern of blood flow in your aneurysm is a bit concerning; perhaps we should treat it.’”
