The physics of clinical MR taught through images /
"To make optimal use of MRI technology, radiologists need an understanding of MRI physics. This can be a difficult area to master for radiologists, and it becomes increasingly challenging as new MRI techniques and new software programs are introduced. While most MRI physics books and chapters a...
