This book is concerned with imaging of the interior of the human body using signals originating from magnetic moments of hydrogen nuclei and detected using a technique known as magnetic resonance. It explains the method and gives examples of applications.The book is addressed to those who would like to understand the principle of the method exactly, but do not have university training in physics and mathematics. It will therefore be very useful to medical practitioners and researchers, radiologists, and auxiliary workers in the health service.
Part 1 The fundamentals: periodic motion; a few words about vectors; the Fourier transformation; magnetic moments and magnetic fields; electromagnetic induction; sampling of the potential; atomic nuclei. Part 2 Magnetic behaviour of the nucleus: nuclear magnetization; longitudinal relaxation; Larmor precession; nuclear magnetic resonance; free induction decay; spin echo. Part 3 Imaging: experimental procedure; transformation of the results; contrast adjustment; contrast agents; MRI angiography; localized spectroscopy. Part 4 Practical aspects: specimen images; indications and contraindications.
