Chest CT of Lung Injury 1 Year after #COVID19 Pneumonia

The researchers assessed lung abnormalities on chest CT in 91 participants, mean age 59 years, at several points over one year after the onset of COVID-19 symptoms.

At one year, CT abnormalities were present in 49, or 54%, of the 91 participants. 

Of these 49 participants, two (4%) had received outpatient treatment only, while 25 (51%) were treated on a general hospital ward and 22 (45%) had received intensive care unit (ICU) treatment.

While CT abnormalities decreased in initial follow-ups, 63% of participants with abnormalities did not show any further improvement after six months. 

Age over 60 years, critical COVID-19 severity and male gender were associated with persistent CT abnormalities at one year.
