Physiologists Playing with Protons

Magnetic Resonance Imaging of the lung is not commonly used because of the combined effects of  low proton density (the lung is mostly full of air) and rapid signal decay from magnetic susceptibility effects from the myriad of air-tissue interfaces.
Nevertheless, proton MRI is an attractive imaging  modality, as it carries no dose of ionizing radiation making it suitable for studies in which repeated imaging is required.
Our group has developed methods to quantitatively measure lung density (providing a measure of air to tissue ratio), perfusion without the use of exogenous contrastagents, and ventilation using only O2 as a contrast agent.Together these allow quantitative insight into the primary function of the lung, gas exchange.
