Respiratory function imaging

Bioxydyn offers imaging biomarkers for respiratory diseases such as cystic fibrosis, asthma, pulmonary hypertension, interstitial disease and COPD. We are the world leaders in delivering oxygen-enhanced MRI (OE-MRI) for imaging lung function.


OE-MRI is a non-invasive and non-ionising imaging method that uses oxygen as an MR imaging agent, which is delivered to the patient in the scanner. OE-MRI can be deployed on most hospital MRI scanners.

Lung OE-MRI monitors the delivery of oxygen to the patient's lungs and the acquired quantitative imaging biomarkers relate to regional lung ventilation and gas diffusion in diseases such as chronic obstructive pulmonary disease (COPD), cystic fibrosis, and asthma. 

The images show ventilation defects in an adult cystic fibrosis patient. Blue regions show parts of the lung that are receiving oxygen; the black regions of the lung represent areas with no detectable oxygen delivery.

Bioxydyn is also a leader in dynamic contrast-enhanced MRI (DCE-MRI) in the lung, providing information on lung perfusion and other microvascular function, including endothelial permeability and leakage space in diseases such as pulmonary embolism, asthma, pulmonary hypertension, interstitial disease and COPD.

Bioxydyn also provides imaging biomarkers of lung ventilation based on the motion of the lung over time. These measurements provide ventilation-weighted imaging in a short scan without administration of gases or contrast agents.
