Design outcomes

Primary

MeasureTime frame
Whole brain and Region of Interest (ROI) are used to compare the brain distribution (neural activity) of [15O]H2O during resting breathing, voluntary cough, cough suppression and cough induction.

Secondary

MeasureTime frame
Correlation between objective parameters of cough (PEFR) and brain activity (PET, MRI images)
