团注追踪3DCE-MRA在腹部、盆腔及双下肢血管成像中的应用

3D CE MR angiography technique of abdomen and lower extremity arteries with Moving-Bed Infusion Tracking

目的探讨团注追踪3D CE-MRA在腹部、盆腔及下肢血管成像中的应用意义。方法对48例疑有腹部、盆腔及下肢血管疾病的患者行团注追踪3D CE-MRA检查。使用Philips gyroscan intera 1.5T超导磁共振机,采用体部正交线圈,运用其独特的Bolustrack和Mobitrack结合的智能化扫描技术,移床跟踪采集腹部、盆腔及双下肢动脉血管图像。结果48例患者的腹部、盆腔及双下肢动脉成像均获得满意的效果,血管清晰,病变明确。结论团注追踪3D CE-MRA在腹部、盆腔及双下肢血管成像中有着重要的临床意义,是目前能部分取代DSA和3D CE-CTA的一种新的血管成像技术。

Objective: To evaluate the advantages and clinical efficacy of 3D CE-MRA of abdomen and lower extremit arteries with Moving-Bed Infusion Tracking. Methods: 48 cases with suspicious disease of abdomen and lower extremity arteries were performed by dynamic 3D scan examination, the images of the abdomen and lower extremity arteries were rapidly collected using Philips Gyroscan Intera 1.5T MR scanner, which particularly has the intellectualized scan technique with Bolustrack and Mobitrack. Results: Arteries in all cases were well demonstrated and diagnosis was definite. Conclusions: The dynamic 3D CE-MRA technique of abdomen and lower extremity arteries can be a new technique instead of DSA and CTA at present.
