The hybrid multibreath
imaging technique has been previously used to measure
regional lung parameters such as p
specific ventilation (SV) and ADC measurements
simultaneously. The combination of these three imaging
measurements effectively probes the different aspects of
lung disease in a manner analogous to current clinical
measurements. The obtained measurements are highly
correlated with conventional pulmonary tests (pulmonary
function test, six-minute walk test, and the St.
Georges Questionnaire). In this study, the p
SV and ADC measurements acquired using the hybrid
technique were assessed for their viability as markers
for distinguishing between smokers and nonsmokers.
