Disease activity in giant cell arteritis (GCA) patients can be well monitored by ultrasound. The number of temporal arterial segments with halo sign, and temporal arterial intimal-media thickness were sensitive to change over 24 weeks. Moreover, halo features and disease activity markers demonstrated significant associations. These results were not found for axillary arterial halo features [1]. In patients aged ≥50 years, GCA is the most prevalent form of primary vasculitis. Irreversible blindness occurs in up to 30% of the cases. Although high dose glucocorticoids are an effective treatment, toxicity is a major problem and occurs in over 80% of patients. Therefore, a correct diagnosis and accurate monitoring of the disease are important. In prior studies, a non-compressible halo sign of the temporal and axillary arteries has demonstrated discriminative value for diagnosing GCA [2]. The current 2-centre, prospective study aimed to assess the potenti...
