Researchers at the University of Montreal Hospital Research Centre (CRCHUM) have developed virtual models that can be used in angiography rooms to address aortic aneurysms and help medical professionals visualize the area being treated. To provide more personalized treatments, the new software maximizes the use of images generated with current ultrasound, scanning, and magnetic resonance imaging (MRI) technologies.
Using scanner images, the research of Dr. Gilles Soulez provides three-dimensional images of all components of an aneurysm, for example, the light, the thrombus or clot, the wall, and the calcification. The group's new simulations will better predict the risk of rupture, adding biomechanical properties such as tissue elasticity and connectivity at each pixel of the image.
Current images produced by X-ray show the vessels and the stent being inserted, but not the wall. The traditional approach also requires a fair amount of dye, which can be toxic for the patient if used in excessive amounts.
The new approach from the University of Montreal uses a computer to automatically recognize the tools introduced into the body and correct the deformities they cause.Dr. Soulez's research in interventional radiology also aims to ensure that the “plumbing" installed in patients fits in place and does not leak, which can cause an aneurysm rupture.
