“…Oxygen alters the T 1 -weighted signal intensity of the pulmonary blood circulation ( 14 , 230 , 231 ), permitting indirect imaging of the lungs. During tidal breathing, a series of T 1 -weighted images are acquired using a conventional MRI scanner during both normoxic and pure oxygen conditions ( 232 , 233 ), with output data represented as T 1 maps or quantified as relative enhancement ratio or oxygen transfer function (OTF) ( Figure 4 ) ( 235 ). Using these metrics, individuals with CF and COPD were found to exhibit a heterogeneous reduction in T 1 relaxation time compared to healthy individuals ( 233 , 236 , 237 ).…”

Respiratory diseases are leading causes of death and disability in the world. While early diagnosis is key, this has proven difficult due to the lack of sensitive and non-invasive tools. Computed tomography is regarded as the gold standard for structural lung imaging but lacks functional information and involves significant radiation exposure. Lung magnetic resonance imaging (MRI) has historically been challenging due to its short T2 and low proton density. Hyperpolarised gas MRI is an emerging technique that is able to overcome these difficulties, permitting the functional and microstructural evaluation of the lung. Other novel imaging techniques such as fluorinated gas MRI, oxygen-enhanced MRI, Fourier decomposition MRI and phase-resolved functional lung imaging can also be used to interrogate lung function though they are currently at varying stages of development. This article provides a clinically focused review of these contrast and non-contrast MR imaging techniques and their current applications in lung disease.
