目的:探讨相位对比法磁共振血管成像技术对脑血管显示效果及其临床应用价值。方法:收集于瓮安县人民医院影像科2020年8月—2021年7月使用三维时间飞跃法磁共振血管成像(3D time of flight magnetic resonance angiography,3D-TOFMRA)和...目的:探讨相位对比法磁共振血管成像技术对脑血管显示效果及其临床应用价值。方法:收集于瓮安县人民医院影像科2020年8月—2021年7月使用三维时间飞跃法磁共振血管成像(3D time of flight magnetic resonance angiography,3D-TOFMRA)和三维相位对比法磁共振血管成像(3D phase contrast magnetic resonance angiography,3D-PC-MRA)行脑血管检查的32例患者的影像资料,采用主观评价法对两种血管成像技术的脑血管成像质量、血管狭窄显示能力进行评分,总结两种不同技术的血管成像特点及对血管性病变显示效果。结果:两种方法对脑血管图像质量和血管狭窄显示的评分差异无统计学意义(P>0.05),但对部分血管性病变如脑血管动静脉畸形(AVM)的显示效果存在差异。结论:两种方法对脑动脉的显示都能取得满意效果,3D-PC-MRA对AVM的显示效果明显优于3D-TOF-MRA,并能较好观察颅内静脉窦情况,提供更多血管诊断信息,3D-PC-MRA具有较好的临床应用价值。展开更多
For further reaseach on endovascular embolization treatment of AVMs, 54 patients with AVMs treated with embolization were observed. It was found that embolization was an effective procedure for the treatment of AVMs. ...For further reaseach on endovascular embolization treatment of AVMs, 54 patients with AVMs treated with embolization were observed. It was found that embolization was an effective procedure for the treatment of AVMs. Combined treatment of AVMs with presurgical embolization and direct surgery could reduce the comphcations resulting from large and high flow AVMs with lone surgical removal.展开更多
