People living with long Covid after being admitted to hospital are more likely to show some damage to major organs, according to a new study.
MRI scans revealed patients were three times more likely to have some abnormalities in multiple organs such as the lungs, brain and kidneys.
Researchers believe there is a link with the severity of the illness.
It is hoped the UK study will help in the development of more effective treatments for long Covid.
The study, published in Lancet Respiratory Medicine, looked at 259 patients who fell so ill with the virus that they were admitted to hospital.
