Searching for Predictors of Temporal Artery Biopsy Positivity in Giant Cell Arteritis

Diagnostic accuracy in patients with giant cell arteritis (GCA) is paramount given the need for immunosuppressive treatment, which carries significant potential for side effects. Temporal artery biopsy (TAB), the gold-standard diagnostic test, has variable sensitivity. MRI, in addition to Doppler ultrasound, may have a potentially valuable role in the diagnosis of GCA. In our study, we reviewed the experience in our medical center to identify predictors of positive and negative TAB in patients with GCA
