This book is just great ... Wed 2nd year student, I understood MRI through this book, I use it for all the rest also ... It is simple, clear, precise, diagrams are great and all in color. Would definitely recommend, moreover in my class, many comrades bought after laminated mine. It includes all the physics of radio, scanner, Doppler ultrasound, nuclear medicine, radiotherapy, radiobiology, MRI etc. It is very easy to read and very quickly becomes a companion revisions! Do not hesitate to purchase it, it really will become a reference and I think even those who do not like the physics and technology will enjoy reading it!
