Abstract:
In the past, the diagnosis and course of Takayasu arteritis were monitored by following angiographic findings, in addition to clinical symptoms and biological tests. More recently, cross-sectional imaging techniques especially Computed Tomography (CT) depicted mural changes in aorta and main vessels in this disease. Within the same acquisition, spiral mode also allows to show luminal changes, similarly to conventional angiography. In addition to its diagnostic value especially in the early phase of the disease, CT seems accurate in the follow-up of treated patients and may be proposed as a therapeutic guide. CT features are presented, according to the stage of the disease and the vessels involved.
