Imaging the Vasculitides.

"Neuroimaging plays a vital role in the diagnosis of primary and secondary vasculitic disorders. There multiple neuroimaging options available to accurately describe the underlying clinical deficits of involved cases. Noninvasive neuroimaging modalities provide less risk and when interdigitated, form the basis for a more conclusive understanding of the disease process. There are instances in which invasive cerebral angiography may be needed to image the intricate and at times, small involved vessels. Neuroradiologists should be included in the multidisciplinary team of physicians caring for patients with vasculitides and in research to provide more sensitive and safe modalities for accurate diagnosis."
