摘要
目的评价磁共振平扫及三维增强MR血管造影(3D CEMRA)在主动脉病变中的诊断价值。方法使用GE Signa1.5T扫描仪对31例临床怀疑主动脉病变的患者行MRI平扫及单次屏气三维增强扫描检查,并与彩超、DSA及手术所见进行对照分析。结果8例为主动脉夹层,另23例分别为动脉瘤、主动脉弓畸形、大动脉炎及动脉硬化。31例患者中8例行手术治疗,MRI与手术对照诊断符合率为100%(8/8),19例行彩超检查,MRI检查与彩超结果对照诊断符合率为89.5%(17/19),3例行DSA检查确诊,MRI结果与其相符。结论MR成像,尤其3D CEMRA是一种无创、快速、准确诊断主动脉病变的影像学检查方法,能指导治疗方案的制定,对手术有较大的帮助。
Objective To evaluate the value of conventional MRI and three - dimensional contrast enhanced magetic resonance angiography（3D CEMRA）for diagnosing the aortic diseases. Methods Thirty - one patients with clinically suspected aortic diseases underwent conventional MRI and 3D CEMRA, in addition, surgery, color Doppler uhrasonography（CDUS）and digital subtraction angiography（DSA） were performed in 8, 19 and 3 cases, respectively. MRI findings in all patients were comparatively analyzed with those of surgery, CDUS and DSA. Results Among 31 cases, 8 were aortic dissection, while other 23 were aneurysms, aortic arch defermities, big - arterititis and arterial sclerosis, respectively. 8 patients underwent surgery whose corresponding rate to MRI was 100%, 19 patients underwent CDUS whose corresponding rate to MRI was 89.5%, and 3 patients underwent DSA whose corresponding rate to MRI was 100%. Conclusion MRI, especially 3D CEMRA is a noninvasivc, rapid and accurate method in the diagnosis of aortic diseses and it can provide the reliable evidence for planning therapeatic protocol or surgery.
