Exclusion Criteria:
The presence of any of the following will preclude inclusion:
* Low affinity binder for TSPO ligands based on genotyping for single nucleotide polymorphism (SNP) rs6971.
* Any use of immunomodulatory drugs or biologic agents (such as azathioprine, mycophenolate, methotrexate, ciclosporin, cyclophosphamide etc.) within 12 months prior to screening visit, or between screening and baseline.

* Treatment with oral corticosteroids for greater than 2 weeks within 12 months prior to screening visit, or any oral or injected steroid use within 3 months prior to screening visit, or between screening and baseline.
* Regular use of non-steroidal anti-inflammatory drugs (NSAIDs) - including aspirin \> 75 mg, naproxen, ibuprofen and meloxicam - on more than 2 days per week.
* Known inflammatory or autoimmune disease.
* Chronic or latent infection.
* Severe infection requiring the use of parenteral antimicrobial agents within 2 months prior to screening visit, or between screening and baseline.

* A known genetic mutation associated with PD.
* A positive test for human immunodeficiency virus (HIV), hepatitis B (HBV)/C (HCV) or syphilis.
* Chronic liver disease.
* Any concurrent medical or psychiatric condition or disease that is likely to interfere with the trial procedures or results, or that in the opinion of the investigator, would constitute a hazard for participating in this trial.
* Women of childbearing potential - female participants must be surgically sterile or be post-menopausal. (A post-menopausal state is defined as no menses for 12 months without an alternative medical cause).
* Male participants must be surgically sterile or must agree to use effective contraception during the period of therapy and for 6 months after the last dose of the trial treatment.
* Known hypersensitivity to dapansutrile or its excipients.
* Received an investigational drug or used an invasive investigational medical device within 12 weeks before the screening assessment, or is currently enrolled in another interventional investigational trial. Participants currently enrolled in other observational studies may be recruited.
* Contraindications to PET-magnetic resonance imaging (MRI) scanning including metal implants, claustrophobia or inability to lie flat for 90 minutes.
* Concomitant treatment with any medications that could interfere with \[18F\] DPA-714 binding (e.g., benzodiazepines).
* Current use of any drugs of abuse or average alcohol intake of \>21units per week over the last 3 months.
* Any other significant disease, disability or investigation result which, in the opinion of the Chief Investigator (CI), may either put the participant at risk, or may influence the result of the trial, or the participant's ability to participate in the trial.
