    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study

Assessing disease activity in people with Takayasu's arteritis is difficult, as most people with the disease do not exhibit visible, measurable symptoms. Combination positron emission tomography/computed axial tomography (PET/CT) is a particularly sensitive, accurate scanning method that may improve researchers' ability to evaluate people with the disease. This study will determine the effectiveness of PET/CT in assessing disease activity in people with Takayasu's arteritis.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
