A Long-term Follow-up Study of Pulmonary Function Changes Using Phase-resolved Functional Lung MRI in Patients With COVID-19

Recruiting

• Conditions: Pulmonary Function

• Registration Number: NCT05933317
• Lead Sponsor: Beijing Chao Yang Hospital

Brief Summary

So far, the number of COVID-19 infections worldwide has exceeded 700 million. Long-term damage to the lungs is a major sequela of COVID infection. Pulmonary function testing is an important means for the evaluation of lung damage. MRI examinations with free breathing and no contrast agent can prevent patients from suffering from ionizing radiation damage caused by multiple CT examinations.
