Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
magnetic resonance imaging (MRI)
The test will be administered a trained medical physicist and radiology technologist at the Centre for Cardiac Magnetic Resonance Imaging at the University of Auckland. Each participant will have one MRI and the torso will be imaged. There is no radiation dose. The procedure takes approximately 30 minutes. Eight healthy volunteers have already been recruited and the data from those participants helped set the algorithms for the study of 8 participants with diseased lungs

Early detection / Screening
Comparator / control treatment
The eight healthy volunteers were used to set the imaging parameters in this pilot study. There will be no direct comparison of physiologic or imaging data and hence they are not true controls. That part of the study has been completed
Control group
Uncontrolled

Outcomes
Primary outcome [1] 308157 0
MRI measured regional ventilation/perfusion ratio (V/Q)
Timepoint [1] 308157 0
at time of measurement
Secondary outcome [1] 354102 0
tolerance of procedure will be measured by whether the patient can lie flat for the duration of the test. Tests that are aborted because of patient discomfort will be noted. There is no validated tool that allows us to describe this better. We will ask patients if they would consider that MRI is a test that they would consider having as part of routine diagnosis based on their experience on the day. This is a pilot study.

Summary
Brief summary
The aim of the study is to develop functional MRI capabilities at the Centre for Advanced MRI (CAMRI) to measure regional lung function. This is a proof of concept study - to develop, test and establish functional MRI techniques – providing a non-invasive, non-ionising imaging method to measure regional ventilation, perfusion and tissue density in the lung. Initial protocol development has been undertaken in approximately 8 healthy volunteers. This will now be followed by a comparative study of measurements of ventilation (V) and perfusion (Q) in approximately 8 patients with various respiratory disease (with known V/Q dysfunction) against data from 8 healthy age matched volunteers.
