Before I went into the army after graduate school, I was certain that I wanted to be a newspaper reporter. After two years of service at a regional army headquarters in Chicago, I wondered if I sho...

Rationale and Objectives Application of a previously developed model-based algorithm on hyperpolarized (HP) 3 He magnetic resonance (MR) dynamic projection images of phantoms was extended to inve...

Rationale and Objectives Many imaging modalities and methodologies exist for evaluating the pulmonary airways. Individually, each modality provides insight to the state of the airways; however, al...

Rationale and Objectives Hyperpolarized 3 He magnetic resonance imaging ventilation defects have been observed in subjects with respiratory disorders. We quantified 3 He ventilation defects in e...

Rationale and Objectives Using a novel 129 Xe polarizer with high throughput (1–2 L/hour) and high polarization (∼55%), our objective was to demonstrate and characterize human pulmonary applicati...

Rationale and Objectives Diffusion magnetic resonance imaging (MRI) with hyperpolarized 3 He gas is a powerful technique for probing the characteristics of the lung microstructure. A key paramete...

Rationale and Objectives Although multiple detector computed tomography (MDCT) and hyperpolarized gas magnetic resonance imaging (HP MRI) have demonstrated ability to detect structural and ventila...

The order of the authors for the above article is incorrect. The correct order should be: Li-qiu Zou, MD, Jing-xia Xie, MD, Hui-shu Yuan, MD, Xin-long Pei, MD, Wen-tian Dong, MD, Peng-cheng Liu, MD...

It is an exciting time for pulmonary medicine. Genetic and molecular techniques are providing deeper insight into disease mechanisms. As a consequence, diseases are increasingly defined by genetic,...

The following abstracts of diagnostic radiology research and training grants funded by the National Institutes of Health (NIH) were awarded to principal investigators (PIs) whose primary appointmen...
