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
Imaging of the lungs using non-ionizing approaches such as hyperpolarized 3He and 129Xe magnetic resonance imaging (MRI) is a useful tool both for research and clinical applications. This work focused on development of 129Xe MRI techniques to investigate inflammation in rat lungs. A rodent model of inflammation, specifically radiationinduced lung injury (RILI) was developed using a collimated 60Co source. A quantitative MRI technique measuring absolute ventilated lung volume (values obtained from rats using the previously established 3He method and those obtained with 129Xe, the usefulness of 129Xe for future investigations of.
