Capturing MultiORgan Effects of COVID-19

The COVERSCAN study uses MRI and other tests to look at how COVID-19 affects not just the lungs but multiple organs — including the heart, kidneys, and liver — in patients who had moderate to severe illness. Understanding which organs are damaged and how they recover over time is critical for managing long-COVID and preventing future health problems in survivors. Participants include adults who were hospitalized with moderate-to-severe COVID-19 confirmed by PCR, as well as healthy volunteers without prior COVID infection for comparison. MRI and blood tests are used to assess organ function. You may be eligible if: - You are 18 years or older - You had a confirmed COVID-19 infection (positive PCR test) - Your illness was moderate to severe (requiring hospitalization for more than 48 hours with signs of pneumonia or low oxygen) - OR you have no prior COVID infection (to serve as a control/comparison subject) You may NOT be eligible if: - You have a contraindication to MRI (e.g., pacemaker, ferromagnetic implants, severe claustrophobia, pregnancy) - You have significantly impaired kidney function (eGFR < 30) - You have signs of active COVID-19 infection on the day of your visit - You have another significant medical condition that might interfere with participation Talk to your doctor to see if this trial is right for you.
