Magnetic resonance angiography has made great strides, with continuing improvements in hardware, pulse sequencing, and know-how allowing ever-increasing speed, resolution, and suppression of artifacts. However, an inherent physical barrier has always been limited SNR. Gadolinium contrast agents help to increase SNR by facilitating T1 relaxation, but they can be injected only at a finite rate and at a limited molar dose, and there is a rapid drop in c- centration following the brief arterial phase due to redistribution into the extracellular fluid compartment. With its sixfold increase in T1 relaxivity, blood pool distribution, and longer serum half-life, Vasovist® represents a new breakthro...
This book presents the first in-depth introduction to parallel imaging techniques and, in particular, to the application of parallel imaging in clinical MRI. It will provide readers with a broader understanding of the fundamental principles of parallel imaging and of the advantages and disadvantages of specific MR protocols in clinical applications in all parts of the body at 1.5 and 3 Tesla.
During the past decade significant developments have been achieved in the field of magnetic resonance imaging (MRI), enabling MRI to enter the clinical arena of chest imaging. Standard protocols can now be implemented on up-to-date scanners, allowing MRI to be used as a first-line imaging modality for various lung diseases, including cystic fibrosis, pulmonary hypertension and even lung cancer. The diagnostic benefits stem from the ability of MRI to visualize changes in lung structure while simultaneously imaging different aspects of lung function, such as perfusion, respiratory motion, ventilation and gas exchange. On this basis, novel quantitative surrogates for lung function can be obtained. This book provides a comprehensive overview of how to use MRI for imaging of lung disease. Special emphasis is placed on benign diseases requiring regular monitoring, given that it is patients with these diseases who derive the greatest benefit from the avoidance of ionizing radiation.
This Companion is an essential guide to all aspects of the organ and its music. It examines in turn the instrument, the player and the repertoire. The early chapters tell of the instrument's history and construction, identify the scientific basis of its sounds and the development of its pitch and tuning, examine the history of the organ case, and consider the current trends and conflicts within the world of organ building. Central chapters investigate the practical art of learning and playing the organ, introduce the complex area of performance practice, and outline the relationship between organ playing and the liturgy of the church. The final section explores the vast repertoire of organ music, focusing on a selection of the most important traditions.
The pseudonymous works Kierkegaard wrote during the period 1843–46 have been responsible for establishing his reputation as an important philosophical thinker, but for Kierkegaard himself, they were merely preparatory for what he saw as the primary task of his authorship: to elucidate the meaning of what it is to live as a Christian and thus to show his readers how they could become truly Christian. The more overtly religious and specifically Christian works Kierkegaard produced in the period 1847–51 were devoted to this task. In this book Sylvia Walsh focuses on the writings of this later period and locates the key to Kierkegaard’s understanding of Christianity in the “inverse diale...
