Diffusion Tensor Imaging… Math so scary that even Einstein ran for help! Why the switch from DWI to DTI? What is a tensor, this term Fractional Anisotropy, and why would you spend your time watching this video when you could be watching cat videos and actually enjoying life? Because there are SO MANY cat videos, and SO FEW videos going into the weeds on this critically important subject. So say your goodbyes to Felix and let’s tackle Diffusion Tensor Imaging on the latest episode of MRI Physics Explained!
