AbstractDetermination of disease extension and disease activity are in the foreground of diagnostic imaging in vasculitides. There are several radiologic modalities available each having specific indications. Magnetic resonance imaging (MRI) readily depicts granulomas and mucosal inflammations in the paranasal sinuses, nasal cavity and orbits. Computed tomography detects osseous lesions of the skull. Due to its superb sensitivity MRI is an established screening modality for CNS vasculitides, although there are limitations with regard to specificity. In spite of its limited accuracy in most institutions angiography is still required for radiological confirmation of CNS vasculitis. Perfusion and diffusion MR-imaging may combine the advantages of "conventional" MRI and angiography. By now the method is not fully validated for vasculitides, however. Vascular disease in Takayasu's arteritis and in giant cell arteritis involving predominantly large and medium sized vessels is readily diagnosed by non invasive magnetic resonance angiography. Percutaneous transluminal angioplasty has proven to be an effective and save therapeutic modality for the cure of vascular stenoses and occlusions. Plain film radiography in two planes is the established modality for pulmonary imaging. In pulmonary vasculitides a more thorough analysis of lung disease is provided by high resolution computed tomography. Diagnostic imaging does substantially assist in the interdisciplinary management of patients suffering from vasculitides.
