Although ventilation defects are a significant feature
of
3
He
MRI images of asthmatic lungs, the relationship of those
defects to clinical symptoms of asthma is not well
understood. Using longitudinal
3
He
MRI data, ventilation defects were classified into
categories based on their behavior over time. This
approach will be useful in characterizing the emergence,
reversal, and persistence of such defects in asthmatic
patients. Further studies will investigate the
relationship between emergent ventilation defects and
sites of new airway injury.
