Summary

The goal of this research is to use Helium-3 MRI to see the changes in airflow of the lungs at different times of an attack. These three stages are immediately after the attack, 1 month later and 4-6 months later.

Conditions

  • Asthma Exacerbation

Interventions

DRUG

Helium-3

Patients 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. The first three bags will be administered with a break between each of five to ten minutes. Then the drug aformoterol will be administered and an hour will pass. Then three additional bags will be administered, again with five to ten minutes between each bag.
