Roentgenographic findings in major vasculitic syndromes

Angiography provides valuable diagnostic information in vasculitis. The diagnosis of vasculitis is made by identifying specific arterial abnormalities and their patterns of distribution. Based upon the specific disease in question, the scope of the angiographic procedure needs to be tailored to provide the answer. Other diagnostic modalities, such as Doppler ultrasound, computed tomography, and magnetic resonance imaging, have limited but important roles that have not been fully explored.
