Magnetic Resonance Imaging (MRI) techniques differ e. .This book, which was originally published as a topic issue of "Fast Body MR Imaging" in the European Journal of Radiology, brings together a number of prominent authors. It begins with an overview of the fast MRI techniques.
Magnetic Resonance Imaging (MRI) techniques differ e. Then the current applications and limitations of fast MR imaging are discussed by organ system: heart, lung, kidneys, liver, pancreas and biliary system, and pelvis. Each chapter finishes with a brief paragraph on scope or future direction. The book will guide to the topic of fast MR imaging technique which is changing the whole scope of body MR.
Improvements in gradient performance have made very short repetition and echo times on clinical scanners feasible, thus enabling subsecond image acquisition. The article provides a fundamental overview of the technical aspects from the concept of k-space and k-space segmentation technique, fast MR imaging techniques including fast spin echo, fast gradient echo with or without magnetization preparation to echo planar and hybrid techniques.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from CT and PET scans. MRI is a medical application of nuclear magnetic resonance (NMR).

L, An Introduction to MRI Physics and Analysis Michael Jay Schillaci, PhD, The electric charge of the proton creates a small current loop since the proton is constantly in motion and this generates a magnetic moment current times the area of the loop. The proton magnet differs from the magnetic bar in that it also possesses angular momentum caused by spinning and Analysis Michael Jay Schillaci, PhD In the absence of a strong magnetic field, the spins are oriented randomly.
History of magnetic resonance imaging. Some people think it was invented by Paul C. Lauterbur in September 1971; he published the theory behind it in March 1973.

High-field magnetic resonance imaging. Echoplanar and BOLD contrast imaging Magnetic field inhomogeneities induced by diamagnetic or paramagnetic material in the body linearly increase with field strength. These field inhomogeneities lead to more pronounced distortions in echoplanar images at higher field strength if sequence parameters are not adapted.
