Abstract

The patient was a 15-year-old girl with suspected Takayasu arteritis. Magnetic resonance (MR) imaging, using the fast low angle shot (FLASH) technique, revealed aneurysmal dilation of the aortic root and irregular thickening of the aortic wall. Three-dimensional (3-D) contrast-enhanced MR angiography successfully demonstrated narrowing of the left carotid and left subclavian arteries. In addition, 2-dimensional (2-D) FLASH MR imaging clearly visualized narrowing of two right renal arteries and the left renal artery. These were angiographically evident. Thus, MR imaging is particularly useful for early detection of subtle arteritic changes and involvement of stenotic lesions in branch vessels in the early phase of Takayasu arteritis.

摘要

该患者为一名15岁疑似大动脉炎的女孩。采用快速低角度激发（FLASH）技术的磁共振（MR）成像显示主动脉根部呈瘤样扩张，主动脉壁不规则增厚。三维（3-D）对比增强MR血管造影成功显示左颈动脉和左锁骨下动脉狭窄。此外，二维（2-D）FLASH MR成像清晰显示了两条右肾动脉和左肾动脉狭窄。血管造影证实了这些情况。因此，MR成像对于大动脉炎早期细微动脉炎改变及分支血管狭窄病变累及的早期检测尤为有用。
