CT and MRI in the Evaluation of Thoracic Aortic Diseases
Figure 18
Takayasu arteritis—(a) axial T2-weighted double inversion recovery black blood image in a 31-year-old female patient with Takayasu arteritis shows severe circumferential thickening of the aortic arch (arrows). (b) T2-weighted triple inversion recovery black blood image in the same patient with Takayasu arteritis shows very high signal of the thickened aortic arch (arrows), which is consistent with edema, indicative of active arteritis. (c) 3D contrast enhanced MR angiography images of the arch demonstrate severe stenosis of the left common carotid (LCA), right common carotid artery (RCA), and proximal left subclavian artery (LSCA) with occlusion of the right subclavian artery (RSCA).
