Imaging diagnosis and interventional radiology in systemic vasculitis with particular emphasis on Takayasu arteritis: Part 1

This is a review article describing some new and interesting aspects in the diagnosis and treatment in systemic vasculitis and demonstrating several cases that we have encountered. Particular emphasis will be put on Takayasu arteritis (also known as aortitis syndrome) most commonly observed in Japan and other oriental countries. CT and MRI better demonstrate the vessel wall abnormality of Takayasu arteritis than angiography. Importance of plain chest radiograph should also be kept in mind; it could provide a clue in the diagnosis of Takayasu arteritis in its early stage.

In part 1 of this article, clinical features and imaging findings of Takayasu arteritis (also known as aortitis syndrome) were described in detail. In part 2, treatment of Takayasu arteritis will be first described and discussed. This will be followed by description of clinical features and imaging findings of other systemic vasculitis. Comments on interventional radiology for systemic vasculitis will also be made.
