DCE-MRA在胸腹部大血管病变中的价值探讨

目的探讨DCE-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(fl3d-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DCE-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。

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

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 the radiography pharmaceutical arrived the 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 artries 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.
