It has potentially devastating visually complications and produces a broad range of symptoms and signs that mimic many other medical and surgical conditions. Blood tests reflect the underlying inflammatory process, yet the erythrocyte sedimentation rate (ESR) may be normal in 8% of patients with biopsy proved GCA.1 Nevertheless, making a definitive diagnosis has importance therapeutically as patients are committed to a lengthy oral corticosteroid regimen. Non-invasive techniques, such as colour Doppler or duplex ultrasonography, have been studied in an attempt to improve patient preselection for temporal artery biopsy (TAB).2,3 Magnetic resonance imaging (MRI) has … ER -
