So I just listened to the excellent Episode  #61: Vasculitis and Giant-Cell Arteritis: ‘Rheum’ for improvement [Link is to the podcast and show notes] OCTOBER 9, 2017 By MATTHEW WATTO, MD [Link is to the About Page For Dr. Watto and his cohosts].

This episode features rheumatologist, Dr. Rebecca Sharrim who gives us an outstanding review of vasculitis in general as well as of Giant Cell Arteritis.
The show notes of this episode #61 are perfect so just go there to review the notes.

Since the episode was published there have been new recommendations for imaging of Large Vessel Vasculitis from EULAR – Links to the article are in Resource 2 below. I have included the EULAR imaging recommendations table in the body of this post after the images section.

I’ve embedded the podcast here for my convenience and I’ve followed it with the episode’s wonderful time stamp so I can review whatever part I want.

Here is the figure from the show notes:

Resource (1) below was useful for me in clarifying my understanding of vasculitis classification.

Resource (2) below, EULAR recommendations for the use of imaging in large vessel vasculitis in clinical practice, has excellent recommendations. I have included the Summary Table from the article:

Resource (2), on p 640, also has a useful summary of on the technical aspects of the imaging of large vessel vasculitis:

Box 1 Suggestions for technical and operational parameters on imaging modalities in large vessel vasculitis

Dr. Rebecca Sharim, rheumatologist and guest expert on this podcast, states that one of the keys to a successful rheumatologic diagnosis is a comprehensive rheumatologic review of symptoms. And I in Resource (3) below there is a link to that resource.
