Clinical Trial Summary

Male and female subjects age 18-85 with lung disease will inhale 5ml/kg (patient body weight) hyperpolarized helium and will be scanned using MRI at 3 Tesla, to evaluate the Apparent Diffusion Coefficient (ADC), ventilation defect volume and percent ventilation.


Clinical Trial Description

Briefly, during a one to two hour visit, subjects will provide written informed consent and then undergo: 1. brief medical history and vital signs, 2. full pulmonary function tests, 3. proton MRI, 4. spin-density and/or diffusion weighted Helium-3 MRI. Full pulmonary function tests including spirometry, plethysmography and diffusing capacity of carbon monoxide (DLCO), Lung Clearance Index (LCI) and Airwave Oscillometry (AO) will be performed according to ATS guidelines. MedGraphics Elite Series, MedGraphics Corporation. St. Paul, MN USA and/or nDD EasyOne Spirometer, nDD Medical Technologies Inc. Andover, MA USA will be used. All measurements will be performed in the Pulmonary Function Laboratory at Robarts Research Institute. ;
