"This is a great tool that MRI technologists could use as a trial run for the examination. This is the best type of review book, since it mimics the format of the actual exam. It also would be helpful for seasoned MRI technologists who want to remain fresh in this ever-advancing field." (Doody's, 5 July 2013)
