Key clinical point: This follow-up comparison of fluorescence optical imaging (FOI) with musculoskeletal ultrasound (MSUS) showed that FOI can be considered a useful screening tool for the early diagnosis of psoriatic arthritis (PsA).
Major finding: Patients diagnosed with PsA after the baseline evaluation had a higher prevalence of joints with pathological enhancement in FOI during follow-up (P = .046), notably in phase 2 FOI (P = .037). Similar to MSUS (area under the curve [AUC] 0.77), detecting newly affected joints by FOI (phase 2 in PrimaVista Mode; AUC 0.78) was positively linked with the shift of diagnosis from suspected to confirmed PsA.
Study details: In this follow-up study of 30 patients with psoriasis who had tender or swollen joints, the FOI of both the hands and the grayscale/power Doppler MSUS of the clinically dominant hand were compared.
Disclosures: This study was supported by the BMBF, German Ministry for Education and Research. The authors declared no conflict of interests.
