Overview

The purpose of the study is to learn about the problems that some individuals who recover from a COVID-19 infection continue to have months after they recover from the initial phase of the infection. We will be performing specific type of imaging called x-ray velocimetry. This allows us to understand regional lung ventilation. We will be examining if the measures of regional lung ventilation are more abnormal in participants who have previously had COVID-19 compared to those who have not previously acquired this infection. We will also investigate if the measurements obtained from x-ray velocimetry correlate with ratings of certain symptoms, quality of life ratings, and results of pulmonary function test and a walking test. 

The study includes 1 study visit and will be performed at Tufts Medical Center in Boston, MA.

We expect up to 48 participants will be enrolled in this study at Tufts Medical Center in order to have 40 participants complete the study.
