Synopsis

Keywords: Lung, COVID-19

The long term effects of COVID-19, including those affecting the lung, represent a new global health burden. Lung water density (LWD) MRI is an emerging quantitative technique that can be used to measure relative LWD (rLWD) in 3D. 187 patients were imaged 5 months after COVID-19 recovery using LWD MRI and were compared to 91 healthy controls. The COVID-recovered group displayed significantly higher mean rLWD values as compared to healthy controls. Additionally, local and global patterns of abnormally increased and decreased rLWD were observed in the COVID-recovered group.
