Contrast-enhanced 3D MR angiography. Forty-year-old woman known with Takayasu disease treated with steroids and immunosuppressive therapy (Imuran). At coronal MIP a focal high-grade narrowing of the right subclavian (thin arrows) and less severe stenosis of the left subclavian coronary artery (thick arrow) can be well appreciated. No evidence of aneurysm formation of the thoracic aorta (ascending aorta 32 mm) nor of the side branches.
