In this episode, we speak with a leading investigator in large-vessel vasculitis, Dr. Anne Bull Haaversen, to clarify the full spectrum of giant cell arteritis (GCA), including its aortic involvement. We reviewed the prevalence of GCA-related aneurysms, why the team compared ultrasonography with other imaging modalities, and how the ascending aorta can be assessed with ultrasound. Our Dr. Haaversen summarizes the study design, key findings, and limitations, and reflects on how these results may inform future guidelines. We close by discussing the evolution of their research focus on large-vessel imaging and how rheumatologists can balance advanced diagnostics with empathetic patient care.
