Four-dimensional flow magnetic resonance imaging (4D flow MRI) was utilized to analyze an aortic dissection with an aberrant right subclavian artery, revealing vortex formation and an increased oscillatory shear index (OSI), both indicative of variations in wall shear stress. An elevated OSI has been associated with an elevated risk of aortic dissection.
利用四维血流磁共振成像（4D流MRI）分析一例伴有迷走右锁骨下动脉的主动脉夹层，结果显示存在涡流形成且振荡剪切指数（OSI）升高，这两者均表明壁面剪应力存在变化。OSI升高与主动脉夹层风险增加相关。
