The Utility of MRI in the Diagnosis of Takayasu Arteritis

Figure 2

MRI/MRA through the chest, abdomen, and pelvis was obtained. (a) Axial double inversion recovery sequence through the upper chest demonstrates mural thickening of the brachiocephalic, left common carotid, and left subclavian arteries. (b) Axial double inversion recovery sequence demonstrates mural thickening of the ascending aorta which measures 3.4 cm in diameter. (c) Axial double inversion recovery sequence demonstrates a focal narrowing of the descending aorta, measuring 2.2 cm. (d) Inferior to the focal narrowing visualized in (c), the aorta measures 3.2 cm on axial double inversion recovery sequence. (e) Sagittal oblique cine-FIESTA sequence demonstrates the undulating contour of the abdominal aorta. (f) Axial T2 FIESTA fat saturated sequences through the abdomen demonstrate wall thickening and mural narrowing of the superior mesenteric artery. The white arrow represents in (b) ascending thoracic aorta; (c) and (d) descending thoracic aorta; (f) SMA.
