In large-vessel vasculitis, imaging studies are useful to document temporal artery involvement and crucial to show large-vessel involvement. Color Doppler sonography, magnetic resonance, and computed tomography show early vasculitic lesions. Angiography delineates later vascular complications well. Color Doppler sonography, magnetic resonance angiography, and computed tomography angiography can also be used to show vascular luminal changes. Positron emission tomography is very sensitive in detecting large-vessel inflammation. Imaging procedures can also be used to monitor the course of large-vessel vasculitis. In medium-vessel vasculitis, imaging studies can be used to show both vascular changes and internal organ changes.
在大血管血管炎中，影像学检查有助于记录颞动脉受累情况，对于显示大血管受累至关重要。彩色多普勒超声、磁共振成像和计算机断层扫描显示早期血管炎性病变。血管造影术能很好地显示晚期血管并发症。彩色多普勒超声、磁共振血管造影术和计算机断层血管造影术也可用于显示血管腔变化。正电子发射断层扫描在检测大血管炎症方面非常敏感。影像学检查也可用于监测大血管血管炎的病程。在中等血管血管炎中，影像学检查可用于显示血管变化和内脏器官变化。
