Magnetic Resonance Elastography: Physical Background And Medical Applications
Hirsch S, Braun J, Sack I
Wiley-VCH ISBN-10: 3527340084

Erratum

From the cover:

Magnetic resonance elastography (MRE) is a medical imaging technique that combines magnetic resonance imaging (MRI) with mechanical vibrations to generate
maps of viscoelastic properties of biological tissue. It serves as a non-invasive tool to detect and quantify mechanical changes in tissue structure, which can be
symptoms or causes of various diseases. Clinical and research applications of MRE include staging of liver fi brosis, assessment of tumor stiff ness and investigation of
neurodegenerative diseases. The first part of this book is dedicated to the physical and technological principles underlying MRE, with an introduction to MRI physics,viscoelasticity theory and classical waves, as well as vibration generation, image acquisition and viscoelastic parameter reconstruction.The second part of the book focuses on clinical applications of MRE to various organs. Each section starts with a discussion of the specifi c properties of the organ, followed by an extensive overview of clinical and preclinical studies that have been performed, tabulating reference values from published literature. The book is completed by a chapter discussing technical aspects of elastography methods based on ultrasound.

From the content:

  • NMR and MRI (from Bloch simulations to balanced SSFP-MRE)
  • Motion encoding (from flow compensation to fractional encoding)
  • Theory of elasticity (from generalized Hooke’s law to transverse isotropy)
  • Viscoelasticity (from Kelvin-Voigt to fractal ladders)
  • Elastic waves (from Green’s function to shear wave diffusion)
  • Numerical tools (from phase unwrapping and compact gradient operators to wavelet denoising)
  • Inversion methods (from Helmholtz inversion to waveguide elastography)
  • MRE Hardware (scanners and actuators)
  • Clinical background (the pathological cascade of liver fibrosis, biophysics of cancer, cardiac dysfunction and more)
  • In vivo tissue properties (brain, liver, muscle, heart, spleen, kidney, pancreas, prostate, uterus, intervertebral disc)
  • Ultrasound elastography methods (from ARFI to time harmonic elastography)

Quantification of Biophysical Parameters in Medical Imaging
Sack I, Schäffter T (Editors)
Springer, ISBN-10: 3319659235

Among the 25% most downloaded scientific e-books of Springer

From the cover:

This book provides a selection of essential knowledge on the image-based quantification of biophysical parameters for the purpose of clinical diagnosis. The authors regard clinical imaging scanners as physical measurement systems capable of quantifying intrinsic parameters for depiction of the constitution and biophysical properties of in vivo tissue. On the one hand, this approach supports the development of new methods of imaging highly reproducible, system-independent, and quantitative biomarkers, and these methods receive detailed attention in the book. On the other hand, the reader will also gain a deeper understanding of how physical tissue properties interact with the generation of signals in medical imaging, opening new windows on the intricate and fascinating relationship between the structure and function of living tissues. The book will be of interest to all who recognize the limitations of basing clinical diagnosis primarily on visual inspection of images and who wish to learn more about the diagnostic potential of quantitative and biophysics-based medical imaging markers and the challenges that the paucity of such markers poses for next-generation imaging technologies.

This book reviews current state-of-the-art approaches and technologies in medical imaging. Most of the authors are associated to the Graduiertenkolleg GRK2260 BIOQIC (BIOphysical Quantitative Imaging towards Clinical diagnosis) which is currently funded by the German Research Foundation (DFG).
