    Background And ObjectiveGiant cell arteritis (GCA) is the most frequent systemic vasculitis in adults. In recent years, the usefulness of temporal artery ultrasound (TAUS) as a diagnostic tool to assess the underlying inflammation of the vascular wall during the inflammatory process has been under clinical investigation.Material And MethodsObservational and descriptive cohort study of 120 TAUS in 60 patients with clinical suspicions of GCA, according to the ACR (American College of Rheumatology) classification criteria.ResultsAmong all patients who underwent ultrasound, 42.3% met clinical criteria for GCA according to ACR. Sensitivity and specificity of TAUS in our cohort with clinical suspicion was 81.8% and 93.3%, respectively. A PPV of 90.1% and a VPN of 87.5% were observed.ConclusionOur results showed that TAUS as a useful, indolent, fast, and accessible tool with high diagnostic specificity and diagnostic value.Copyright © 2018.
