Vasculitis & polymyalgia rheumatica
Added diagnostic yield of temporal artery magnetic resonance angiography in the evaluation of giant cell arteritis
Authors' conclusion
TAMRA has proven utility in diagnosing GCA, and these data suggest that it also has utility in identifying alternative diagnoses to rule out the disease. Intracranial vasculitis was also seen in 14.3% of patients
Study context
- Population
- Patients who underwent temporal artery magnetic resonance angiography (TAMRA) for a possible diagnosis of GCA, St Joseph's Healthcare, Hamilton, Ontario, Canada, February 2007–April 2020126 (37.1%) GCA diagnoses
- Participants
- 340 patients
- Outcome
- Other significant abnormalities on TAMRA, either associated with GCA or potentially mimicking GCA
