Experimental: Asthmatic Participants
This population is made up of only confirmed asthmatics. Participants will inhale Hyperpolarized Helium-3: Participants will be required to breath in individual 1 liter bags of gas while in an MRI to produce lung images. These bags of gas are each made up of 333mL of Helium-3 gas and 667mL of Nitrogen. Three bags will be administered to acquire three different scans.

Experimental: Healthy
This population is made up of subjects who are considered clinically healthy. This means that there are no records of any chronic disorders or pulmonary history. Participants will inhale Hyperpolarized Helium-3: Participants will be required to breath in individual 1 liter bags of gas while in an MRI to produce lung images. These bags of gas are each made up of 333mL of Helium-3 gas and 667mL of Nitrogen. Three bags will be administered to acquire three different scans. |

Experimental: COPD Patients
This population is made up of only confirmed COPD patients. Diagnosis must be confirmed through their doctor prior to enrollment. Participants will inhale Hyperpolarized Helium-3: Participants will be required to breath in individual 1 liter bags of gas while in an MRI to produce lung images. These bags of gas are each made up of 333mL of Helium-3 gas and 667mL of Nitrogen. Three bags will be administered to acquire three different scans. |

Detailed Description:
Current pulmonary imaging techniques are clinically regulated to machines that produce radiation. MR which does not produce radiation was not possible due to the low concentration of fluids in the open spaces of the lungs. With hyperpolarized noble gases we can now use the safe techniques of MR imaging to view the airways of the lungs, thus limiting human exposure to radiation. This technique has already been proven to be possible in human subjects but there is insufficient data show its efficacy in a clinical setting. This study is designed to image a variety of pulmonary disorders to better find possible clinical uses for hyperpolarized gas MRI.
