Book Description
Pulmonary magnetic resonance (MR) imaging provides valuable information about lung anatomy and perfusion and ventilation physiology. Oxygen-enhanced MR imaging visualizes the effect of ventilation using inhaled molecular oxygen as a T1-shortening contrast agent. The technique is challenged, however, by low proton density of lung tissue and cardiopulmonary physiology that result in reduced MR signal and increased motion artifacts. With the growing interest in mouse models of respiratory disease, application of human pulmonary MR techniques to mice is highly desirable. The purpose of this work was to develop oxygen-enhanced MR imaging as a non-invasive tool to examine ventilation in free-breathing mice. An optimized cardiac-triggered, respiratory-gated fast spin echo sequence was developed for oxygen-enhanced MR and successfully demonstrated in normal mice. Ventilation was visualized as significant signal enhancement in the lung parenchyma with pure oxygen inhalation. This sequence shows potential for application to studies of abnormal ventilation in models of pulmonary disease.

Book Description
This book provides a comprehensive overview of how to use MRI for the imaging of lung disease. Special emphasis is placed on routine applications and the clinical impact of MRI in each setting. In addition, current technological developments are reviewed and information presented on dedicated applications of MRI in preclinical and translational research, clinical trials, and specialized institutions. During the past two decades, significant advances in the technology have enabled MRI to enter and mature in the clinical arena of chest imaging. Standard protocols are now readily available on MR scanners, and MRI is recommended as the first- or second-line imaging modality for a variety of lung diseases, not limited to cystic fibrosis, pulmonary hypertension, and lung cancer. The benefits and added value of MRI originate from its ability to both visualize lung structure and provide information on different aspects of lung function, such as perfusion, respiratory motion, ventilation, and gas exchange. On this basis, novel quantitative surrogates for lung function and therapy control (imaging biomarkers) are generated. The second edition of MRI of the Lung has been fully updated to take account of recent advances. It is written by an internationally balanced team of renowned authors representing all major groups in the field.

Book Description
Knowledge about the mechanisms of lung development has been growing rapidly, especially with regard to cellular and molecular aspects of growth and differentiation. This authoritative international volume reviews key aspects of lung development in health and disease by providing a comprehensive review of the complex series of cellular and molecular interactions required for lung development. It covers such topics as pulmonary hypoplasia, effects of malnutrition, and pulmaonary angiogenesis. An indispensable reference for all those involved in studying or treating lung disease in neonates and children, the book offers a unique view of the development of this essential organ.

Book Description
Over the past decade, fluorine (19F) magnetic resonance imaging (MRI) has garnered significant scientific interest in the biomedical research community owing to the unique properties of fluorinated materials and the 19F nucleus. Fluorine has an intrinsically sensitive nucleus for MRI. There is negligible endogenous 19F in the body and thus there is no background signal. Fluorine-containing compounds are ideal tracer labels for a wide variety of MRI applications. Moreover, the chemical shift and nuclear relaxation rate can be made responsive to physiology via creative molecular design. This book is an interdisciplinary compendium that details cutting-edge science and medical research in the emerging field of 19F MRI. Edited by Ulrich Flögel and Eric Ahrens, two prominent MRI researchers, this book will appeal to investigators involved in MRI, biomedicine, immunology, pharmacology, probe chemistry, and imaging physics.

Book Description
Hyperpolarized and Inert Gas MRI: Theory and Applications in Research and Medicine is the first comprehensive volume published on HP gas MRI. Since the 1990's, when HP gas MRI was invented by Dr. Albert and his colleagues, the HP gas MRI field has grown dramatically. The technique has proven to be a useful tool for diagnosis, disease staging, and therapy evaluation for obstructive lung diseases, including asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis. HP gas MRI has also been developed for functional imaging of the brain and is presently being developed for molecular imaging, including molecules associated with lung cancer, breast cancer, and Alzheimer's disease. Taking into account the ongoing growth of this field and the potential for future clinical applications, the book pulls together the most relevant and cutting-edge research available in HP gas MRI into one resource. - Presents the most comprehensive, relevant, and accurate information on HP gas MRI - Co-edited by the co-inventor of HP gas MRI, Dr. Albert, with chapter authors who are the leading experts in their respective sub-disciplines - Serves as a foundation of understanding of HP gas MRI for researchers and clinicians involved in research, technology development, and clinical use with HP gas MRI - Covers all hyperpolarized gases, including helium, the gas with which the majority of HP gas MRI has been conducted

Book Description
This textbook is a practical guide to the use of small animal imaging in preclinical research that will assist in the choice of imaging modality and contrast agent and in study design, experimental setup, and data evaluation. All established imaging modalities are discussed in detail, with the assistance of numerous informative illustrations. While the focus of the new edition remains on practical basics, it has been updated to encompass a variety of emerging imaging modalities, methods, and applications. Additional useful hints are also supplied on the installation of a small animal unit, study planning, animal handling, and cost-effective performance of small animal imaging. Cross-calibration methods and data postprocessing are considered in depth. This new edition of Small Animal Imaging will be an invaluable aid for researchers, students, and technicians involved in research into and applications of small animal imaging.
