What This Means for Your Design
Scientists used 3D printing to make a fake blood vessel with a bulge (aneurysm) that mimicked real blood flow. They then used a new imaging technique called MPI, which uses magnets, to watch how blood moved inside. MPI was found to be very good at showing the fast-changing blood flow, even better than some older methods, and it doesn't use harmful radiation.
