MRI Physics for Radiologists by Alfred L. Horowitz Pdf

MRI Physics for Radiologsits: A Visual Approach, Third Edition delineates the principles of magnetic resonance imaging in a format that can be understood by readers who do not have a sophisticated physics or mathematics background. It is organized in three sections: sections one and two present the contrast and spatial characteristics of the image; section three deals with topics such as Half Fourier imaging, motion, aliasing, artifacts, and coils. The third edition has sections on new techniques now in common use, such as rectangular field of view and fast spin-echo (or echo-planar) sequences, a chapter on the effect of MR equipment parameters on image resolution, a chapter with a simplified mathematical discussion of the Fourier transform and an enhanced section on magnetic resonance angiography.

The Physics and Mathematics of MRI by Richard Ansorge,Martin Graves Pdf

Magnetic Resonance Imaging is a very important clinical imaging tool. It combines different fields of physics and engineering in a uniquely complex way. MRI is also surprisingly versatile, 'pulse sequences' can be designed to yield many different types of contrast. This versatility is unique to MRI. This short book gives both an in depth account of the methods used for the operation and construction of modern MRI systems and also the principles of sequence design and many examples of applications. An important additional feature of this book is the detailed discussion of the mathematical principles used in building optimal MRI systems and for sequence design. The mathematical discussion is very suitable for undergraduates attending medical physics courses. It is also more complete than usually found in alternative books for physical scientists or more clinically orientated works.

Basic Principles of Cardiovascular MRI by Mushabbar A. Syed,Subha V. Raman,Orlando P. Simonetti Pdf

This book is a comprehensive and authoritative text on the expanding scope of CMR, dedicated to covering basic principles in detail focusing on the needs of cardiovascular imagers. The target audience for this book includes CMR specialists, trainees in CMR and cardiovascular medicine, cardiovascular physicists or clinical cardiovascular imagers. This book includes figures and CMR examples in the form of high-resolution still images and is divided in two sections: basic MRI physics, i.e. the nuts and bolts of MR imaging; and imaging techniques (pulse sequences) used in cardiovascular MR imaging. Each imaging technique is discussed in a separate chapter that includes the physics and clinical applications (with cardiovascular examples) of a particular technique. Evolving techniques or research based techniques are discussed as well. This section covers both cardiac and vascular imaging. ​Cardiovascular magnetic resonance (CMR) imaging is now considered a clinically important imaging modality for patients with a wide variety of cardiovascular diseases. Recent developments in scanner hardware, imaging sequences, and analysis software have led to 3-dimensional, high-resolution imaging of the cardiovascular system. These developments have also influenced a wide variety of cardiovascular imaging applications and it is now routinely used in clinical practice in CMR laboratories around the world. The non-invasiveness and lack of ionizing radiation exposure make CMR uniquely important for patients whose clinical condition requires serial imaging follow-up. This is particularly true for patients with congenital heart disease (CHD) with or without surgical corrections who require lifelong clinical and imaging follow-up.
