"During the last two decades, new developments in functional MRI (magnetic resonance imaging) have made it possible to detect changes in the brain over time, as opposed to the "snapshot" produced by conventional MRI. Essentials of Functional MRI breaks down the technical challenges for physicians, researchers, and technologists who use functional MRI but may not be experts in the necessary math and physics. The author describes the theory and practical details of functional MRI (fMRI) methodology, including how to acquire and analyze images, and a wide range of examples demonstrate how fMRI has been used thus far. The author provides the essential information to study, understand, use, and teach the practical aspects of fMRI for those people who are most likely to extend its use into clinical practice"--Provided by publisher.

This proceedings volume, the sixteenth in a biannual series, presents a snapshot of the state of current research worldwide on Electron Cyclotron Emission (ECE) and Electron Cyclotron Resonance Heating (ECRH) and related technologies. The papers address the physics, both theory and experiment, of ECE and ECRH. The technologies of high power millimeter-wave sources - gyrotrons - and transmission lines and launchers are included. The focus is on physics and technology relevant to the research and development of nuclear fusion.

Hypoxia, a partial pressure of oxygen (pO2) below physiological needs, is a limiting factor affecting the efficiency of radiotherapy. Indeed, the reaction of reactive oxygen species (ROS, produced by water radiolysis) with DNA is readily reversible unless oxygen stabilizes the DNA lesion. While normal tissue oxygenation is around 40 mm Hg, both rodent and human tumors possess regions of tissue oxygenation below 10 mm Hg, at which tumor cells become increasingly resistant to radiation damage (radiobiological hypoxia) (Gray, 1953). Because of this so-called "oxygen enhancement effect", the radiation dose required to achieve the same biologic effect is about three times higher in the absence of oxygen than in the presence of normal levels of oxygen (Gray et al., 1953; Horsman & van der Kogel, 2009). Hypoxic tumor cells, which are therefore more resistant to radiotherapy than well oxygenated ones, remain clonogenic and contribute to the therapeutic outcome of fractionated radiotherapy (Rojas et al., 1992).

Continuous improvement in MRI technology in recent years has led to the application of diffusion-weighted MR imaging in organ systems outside the brain. Extra-Cranial Applications of Diffusion-Weighted MRI provides an extensive review of current and future applications of this imaging modality by world-renowned experts. Organized by organ system, each chapter is highly illustrated, offering a balance of protocols, illustrations and principles of image interpretation. An initial chapter provides an overview of relevant physics and other technical details, followed by detailed chapters on all major body systems including liver, kidney, prostate, breast and spine. A final chapter discusses assessment of therapy response. Written and edited by leading DW-MRI experts worldwide, Extra-Cranial Applications of Diffusion-Weighted MRI is an invaluable resource for radiology trainees, practising radiologists and for researchers in a wide variety of disciplines.

Since its initial development in the mid-1980's, and wide accessibility to perform diffusion MRI on all MRI scanners, the use of diffusion MRI has exploded. Nearly every MRI centre carries out diffusion MRI of some kind. Obtaining good quality diffusion MRI and making sound and robust inferences from the data is not trivial, however, and involves a long chain of events from ensuring that the hardware is performing optimally, the pulse sequence is carefully designed, the acquisition is optimal, the data quality is maximized while artifacts are minimized, the appropriate post-processing is used,
