Vasculitis, a group of inflammatory diseases affecting the blood vessels, can cause significant damage to internal organs and vital arteries. There are three general types based on the size of the vessel affected: small, medium, and large vessel vasculitis. Large vessel vasculitis (LVV), in particular, can often be difficult to diagnose.

Kimberly Liang, MD, assistant professor of rheumatology at UPMC, has performed extensive research of LVV, and is studying more effective imaging methods for diagnosis and disease monitoring. She explains that through ongoing research, these new techniques may improve the diagnostic and monitoring process.
