The MRI "Echo" - How it Works | MRI Physics Course Lecture 8

After a little detour, we are BACK to the main MRI Physics Explained lecture series! We’ll call this the beginning of the “intermediate” level of lectures focusing on MRI pulse sequences requested from you all by popular demand, and what better way to start than by taking an in-depth look into the Echo? What exactly is this “Echo”? How do we make our signal emerge after dephasing? Why am I incessantly yelling at the MRI machine and these lectures and hearing nothing back? These answers and more on the latest episode of MRI Physics Explained!
