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
COPD and asthma have significant morbidity and mortality. Hyperpolarized (HP) 3He Diffusion MRI has been used to assess lung diseases. The results correlated well with histology, but the diffusion time for previous methods is limited to the order of milliseconds under 1.5 T. New MR methods were developed to measure HP 3He diffusion over the long-time scale (LTS: diffusion time on the order of seconds) in human lungs and were used to investigate COPD and asthma. The basic equations were developed, numerical simulation was performed, and measurements were made in phantoms. Measurements in healthy subjects confirmed that 3He diffusion still strongly depended on the diffusion time in LTS and the ADC decreased significantly. Reproducibility, anisotropy and dependence on parameters were characterized. Experiments in patients with COPD suggested that LTS diffusion was more sensitive to early COPD changes than short-time-scale diffusion. Measurements in patients with severe asthma revealed large regional elevations in LTS ADC maps while the changes in STS were smaller. And there was a good correlation between LTS ADC maps and areas of low-density "air-trapping" seen by CT.

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.
