The trial is looking for adults who had COVID-19 at least 12 months ago, to compare microclots on a PET scan. Post-COVID patients and controls are compared.
- Age
- 40-65 years (the registry lists 18 to 64 years)
- Sex
- All sexes
- Disease stage
- Symptomatic COVID-19 confirmed by a positive PCR test for SARS-CoV-2, at least 12 months ago.
- Earlier treatment
- Must not use anti-coagulant drugs.
- Biomarker or test result
- Positive PCR test for SARS-CoV-2 when COVID-19 was diagnosed.
Main reasons for not taking part
- Other conditions linked to amyloid formation, such as diabetes, rheumatoid arthritis or neurodegenerative disorders
- Cannot undergo scanning, for example due to claustrophobia, severe back pain or fear of needles

What the trial wants to find out
To assess whether we are able to visualize and quantify a difference in amyloid containing microclots between post-COVID patients and controls using total-body dynamic [18F]flutemetamol PET.
