NCT ID: NCT04585113 Completed - Osteoarthritis Clinical Trials

Diagnostic Accuracy of Dual-energy CT

DAD
Start date: October 1, 2020
Phase:
Study type: Observational

The study will include 20 people with hand OA awaiting surgery in the fingers. Participants will undergo dual-energy CT, cone-beam CT, ultrasound, clinical examination, blood sampling and questionnaires. Images will be analysed for the presence of joint-associated crystal including monosodium urate, calcium pyrophosphate and calcium hydroxyapatite. Material obtained during surgery will be used for crystal verification and calculation of diagnostic accuracy of dual-energy CT and cone-beam CT.
