View on ClinicalTrials.gov →
Summary
Ultrasound evaluation of the temporal and axillary arteries is currently well recognized in the field of giant cell arteritis (GCA), a disease primarily affecting medium- and large-caliber vessels. Structural ultrasound abnormalities are now well described in this pathology, but their association with relapse and clinical concordance is unknown. There is currently a follow-up score (the OGUS score) for medium- and large-caliber arteries that could also predict the clinical course of the disease.
