A Complete Guide to MRI Technology, Medical Imaging, and the Magnetic ForcesBy Harold M.Stevens
Length2h 43m
About this audiobook
Most people lie inside an MRI scanner and have no idea what it's doing. This book changes that.
A Complete Guide to MRI Technology, Medical Imaging, and the Magnetic Forces That Reveal Everything takes you inside the world's most sophisticated diagnostic machine — from the superconducting magnet cooled to near absolute zero, to the millisecond-by-millisecond process that turns atomic signals into crystal-clear images of your brain, heart, and spine.
Gripping. Authoritative. Written for real people — not textbooks.
If you've ever had an MRI, know someone who has, or simply want to understand one of humanity's greatest scientific achievements — start here.
