Vasculitis & polymyalgia rheumatica
Biopsy vs imaging in the diagnosis of giant cell arteritis. Viewpoint 1: in favour of imaging
Authors' conclusion
A suspected diagnosis of GCA should be confirmed or excluded via imaging or TAB. Imaging, particularly US, offers several advantages over TAB as the initial diagnostic test.
Study context
- Population
- Suspected giant cell arteritis (GCA)
- Comparison
- Imaging vs temporal artery biopsy (TAB) as the primary diagnostic method for suspected GCA
- Outcome
- Advantages of imaging over TAB

Main finding
As reported in the abstract
- Author advocates imaging, particularly US, as the initial diagnostic test, in line with EULAR recommendations
- Imaging is non-invasive, reliable, sensitive also to extracranial GCA, and specific
- US is widely available, cost-effective and patient-friendly
- Fast-Track Clinics with rapid access to specialist care and US have reduced instances of permanent vision loss
- If clinical presentation and imaging are not conclusive, a second test (PET for suspected extracranial GCA, or TAB for suspected cranial GCA) should be conducted
- Diagnostic process should not delay initiation of GC treatment
