DCE-MRA在胸腹部大血管病变中的价值探讨

Diangostic Evaluation of DCE-MRA for Thoracic and Abdominal Great Vessel Disease

目的：探讨DEE—MRA在胸腹部大血管病变诊断中的价值。材料与方法：收集我院31例患者的资料，使用SIEMENS公司生产的1．5T磁共振机。应用梯度回波加脂肪抑制层块扫描技术（f13d—cor-fs），经肘静脉快速注入20ml造影剂后8-15s开始对靶血管区行屏气扫描。结果：31例中主动脉离断2例，大动脉炎3例，肾动脉狭窄10例，腹主动脉硬化合并局限性动脉狭窄及动脉瘤．1例，动脉硬化合并左锁骨下动脉狭窄1例，主动脉夹层4例，肺癌侵及肺动脉及分支5例，纵隔恶性淋巴瘤侵及心脏和周围血管1例，布加综合征4例，均能明确诊断且与DSA有良好的诊断符合性。结论：DEE—MRA在胸腹部大血管病变的诊断中作用显著，可作为筛选胸腹部大血管病变首选检查方法，且对临床治疗有指导意义。

Purpose： To evaluate the diagnostic value of dynamic contrast- enhanced magnetic resonance angiography （DCE- MRA） in thoracic and abdominal great vessel disease. Materials and Methods： 31 Cases were studied with 1. 5T novous MRI （made by SIEMENS） on fl3d- cor- fs. The time of which tile radiography pharmaceutical arrived tile Target blood vessels were accurately controlled. Results： 31 cases of thoracic and abdominal great vessel disease included interruption of aortic arch in 2 cases, aorto - arteritis in 3 cases, renal artery stenosis in 2 cases, abdominal aorta sclerosis amalgamate limitation artery stenosis and aneuysm in 1 case, artery sclerosis amalgamate left subclavain artery stenosis in 1 case, aortic dissection in 4 case, lung cancers invaded their pulmonary amies and branches in 5 cases, malignant mediastinal lymphoma invaded heart and around blood vessel in 1 case, Budd - Chiari syndrome in 4 cases , all of cases can be diagnosed clearly, and there are good consistent according with DSA. Conclusion： The function is remarkable among DCE - MRA is in diagnosis of the thoracic and abdominal great vessel disease. It can regard as the first＂ selected insepection method of disease of chest belly trunk, and to treating directive significance clinically.
