Overview
MRI can demonstrate mural thickening with luminal stenosis of the aorta and branching vessels of the aortic arch. It can directly visualize the vessel wall independent of luminal diameter and can be helpful in diagnosis of inflammation in early vasculitis.
Key MRI findings in Takayasu's arteritis
MRI may be helpful in the diagnosis of Takayasu's arteritis. Features that might be seen on MRI are as follows:[1][2]
- Mural thickening with luminal stenosis of the aorta and aortic branch vessels
- Visualizing of the vessel wall
- Detecting pathologic features of the arterial wall
- Diagnosis of inflammation in early vasculitis that may manifest as:
