| 目的 探讨彩色多普勒超声(CDFI)与三维增强磁共振血管成像(3D CE MRA)在糖尿病椎-基底动脉供血不足(VBI)患者病因诊断中的价值。方法 对46例糖尿病患者临床诊断椎-基底动脉供血不足患者行3D CE MRA及CDFI检查,观察椎动脉走形、管径,是否存在狭窄、血流参数以及病变的部位。结果 CDFI检查阳性38例,其中单侧椎动脉受累32例,双侧受累6例。3D CE MRA检查阳性发现者40例,其中单侧椎动脉受累33例,双侧受累7例,两种方法对对椎动脉狭窄 |

| Objective To evaluate the diagnostic values of color doppler flow imaging (CDFI) and three dimentional contrast enhance magnetic resonance angiography (3D CE MRA) in patients with vertebral arterial insufficiency of diabetes mellitus. Methods Fourty-six vertebral arterial insufficiency patients in diabetes mellitus were diagnosed clinically. All the patients were examined by CDFI and 3D CE MRA to investigate the tracks, diameters and stenosis location of vertebral arterials. Results CDFI was positive in 38 patients with 32 ipsilateral and 6 bilateral. 3D CE MRA was positive in 40 patients with 33 ipsilateral and 7 bilateral. The both methods had higher accordence in vertebral arterial insufficiency (88.1%), and in diagnosis of vertebral arterial obstruction was 100%. Conclusion CDFI can observe the samll change and light stenosis more accurately, but it can not display the whole vertebral arterial with bone shadows. 3D CE MRA was a useful tool in diagnosing diffused, long segmental artery stenosis and obstruction. The disadvantage was its lower sensitivity in samll pathological changes or light stenosis and posture demand during examination. |
