摘要
目的 :评价MRI在诊断主动脉缩窄中的作用和影像学表现。方法 :主动脉缩窄患者 16例 ,单纯型 14例 ,复杂型 2例 ,其中 1例合并动脉导管未闭 ,4例合并动脉瘤 ,1例合并DebakeyⅡ型主动脉夹层。 16例均经手术证实。全部病例MRI检查包括SE序列、CineMRI和三维动态增强磁共振造影 (3DDCEMRA)。结果 :16例MRI检查均清楚显示主动脉缩窄的部位、范围和程度 ,与手术所见完全一致。结论 :MRI检查是诊断主动脉缩窄的可靠方法之一 ,可多方位、直观的显示病变部位及合并畸形 ,基本上可替代心血管造影 ,为临床手术提供明确的定位和定性诊断 ,MRI可作为诊断主动脉缩窄的首选方法之一。
Objective: To evaluate the imaging feature and the roles of congenital coarctation of the aorta. Methods: Sixteen patients with coarctation of aorta were studied, including 14 cases of simple type and 2 cases of complex type. All of them underwent surgery and were examined by MRI including SE sequence, Cine MRI, 3 dimension dynamic contrast enhanced magnetic resonance angiography (3D DEC MRA) scanning. Results: 16 cases of coarctation of aorta studied by MRI can directly show the whole picture of abnormality, including the position, limits and degree, in comparison with operation was almost accordance. Conclusion:MRI is a noninvasive technique with excellent accuracy in the diagnosis of congenital coarctation of aorta, it well shows the position, extent and degree of coarctation of aorta, and may basically replace X-ray angiography.
