Book Description
Lung transplantation is the established treatment for patients with chronic, end-stage lung diseases such as chronic obstructive pulmonary disease (COPD), idiopathic pulmonary fibrosis (IPF) and cystic fibrosis (CF). However, its utility remains limited by the chronic shortage of donor lungs, limited lung preservation strategies and post-transplant complications leading to graft failure. Although efforts have been made to expand the limited pool of viable donor lungs via novel preservation strategies such as ex vivo lung perfusion (EVLP), our limited understanding of the mechanism and progression of donor lung injury continues to inhibit our ability to fully exploit these advances to improve lung transplant outcomes. Furthermore, the clinical standard for post-transplant assessment is limited to whole lung measurement such as pulmonary functional tests (PFTs) and structural imaging via radiography or HRCT, both of which lack the necessary sensitivity to detect lung rejection early. Given these limitations of currently available pre- and post-transplant lung assessment tools, a novel metabolic biomarker may provide higher sensitivity for determining the viability of donated lungs, as well as for assessing the onset of rejection before permanent structural changes in the lungs become apparent. We proposed that hyperpolarized (HP) [1-13C]pyruvate magnetic resonance imaging (MRI)--which provides real-time metabolic assessment of tissue based on the conversion of [1-13C] pyruvate to [1-13C]lactate via glycolysis, or to 13C bicarbonate via oxidative phosphorylation--may be an effective tool for assessing the health of donated lungs and may also serve as an early biomarker for detecting pulmonary graft dysfunction (PGD)-associated inflammation or acute lung rejection. In a rat model, we demonstrated the feasibility of using HP [1-13C]pyruvate nuclear magnetic resonance (NMR) spectroscopy to assess the viability of ex vivo perfused lungs. We further showed that our technique can be used to measure the improved viability of those lungs after treatment with ascorbic acid. Finally, translating our previously developed technique to in vivo HP [1-13C]pyruvate imaging of an inflamed rat lung, we not only demonstrated its utility for detecting lung transplantation rejection, but found that the HP lactate-to-pyruvate ratio is a better predictor of acute lung rejection in a rat model than computed tomography.

Book Description
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.

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
The advent of contrast-enhanced MRA in the early to mid 1990s revolutionized the clinical approach to vascular imaging: an accurate non-invasive imaging modality, not requiring ionizing radiation or potentially nephrotoxic iodinated contrast media, was able to compete with the more hazardous and invasive catheter angiography. Today, MRA is a safe, easy-to-perform procedure routinely used in most imaging centers, and the continued development of faster, more powerful magnets and more effective contrast agents is increasingly helping to overcome many of the early limitations of the technique. Subdivided into three sections (technique, indications and practical applications) and written by internationally renowned experts in the field, this volume stands out in the current literature on MRA by providing: - detailed information on sequence parameters for different magnets and vascular territories for the optimization of the MRA technique; - a broad overview of the principal indications for which contrast-enhanced MR angiography is ideally suited; - the typical MR imaging findings associated with various pathologies; - the appropriateness of contrast-enhanced MRA as compared with other modalities, such as CTA and CEUS; - the potential pitfalls and limitations of the technique in clinical routine. The volume will prove invaluable to radiologists and clinicians wishing to expand, improve, or consolidate their routine approach to vascular MR imaging.

Book Description
For a long time, imaging of the chest was based on the use of either radiography, demonstrating lung morphology, or scintigraphy, looking at lung function. However, as a result of recent developments in CT and MRI technology it is now possible to perform dedicated investigations of different aspects of lung function, such as ventilation, perfusion, gas exchange, and respiratory mechanics. This volume, written by acknowledged experts in the field, provides a well-illustrated and comprehensive review of these novel approaches to functional imaging of the chest. It will be of great assistance to all who are establishing such strategies in the research or clinical arenas for the diagnostic work-up and follow-up of patients with lung diseases.

Book Description
Chronic graft versus host disease (GVHD) is the most common complication of allogenic bone marrow transplantation. Because of the protracted clinical course of chronic GVHD, transplant centers and hematology/oncology offices are inadequately equipped to manage these immuno-incompetent patients with a multi-system disorder. Practitioners need to be able to recognize and effectively manage chronic GVHD as a late effect of more than half of allogenic transplantations. The text is oriented for the clinician, with chapters covering staging, organ site and system-specific manifestations, treatment options, and supportive care. Drs Georgia B. Vogelsang and Steven Z. Pavletic have been pioneers in the recognition of the multi-organ complexity of this disease and have gathered the input of a variety of subspecialist physicians for this book. This book fills the gap in practical literature on chronic GVHD, providing a comprehensive, up-to-date, and clinically relevant resource for anyone who deals with cancer patients post-transplant.
