Xe Gas<unk>  of Healthy and Diseased Lungs. Colors show different intensities of Xe Gas. 129Xe gas<unk>  is being researched as a diagnostic test for respiratory diseases, such as COPD, asthma, and emphysema. Currently, spirometry pulmonary function tests are used to determine the condition of lung function. However, this is a fairly basic, global assessment of lung function that does not provide specific information about the lung structure and physiology. For structural information, X-Ray CT is most commonly used, but it exposes the patient to high doses of ionizing radiation and it provides no functional information Conventional 1H<unk>  is not effective in the lung airspace because of the minimal proton density. 129Xe gas<unk>  provides detailed, specific information about lung structure and function that are not safely or efficiently obtainable by existing technologies.
