目的：以 DSA 为金标准,探讨 MRA(TOF 法和 PC 法)在脑血管动静脉畸形成像中的临床应用价值。方法收集临床疑为脑血管畸形患者60例为研究对象,3 d 内先后行 MRA(TOF 法和 PC 法)和 DSA 检查,并对供血动脉、畸形血管团及引流静脉进行影像学比较和统计学分析。结果60例脑血管动静脉畸形患者,其供血动脉和小动脉的显示 DSA 和 MRA-TOF 法均优于MRA-PC 法,差异有统计学意义(χ2值/P 值 DSA? PC-4.175/0.000、χ2值/P 值TOF? PC-3.508/0.000),DSA 与 MRA-TOF 法相比,差异无统计学意义(χ2值/P 值 DSA? TOF-0.740/0.459)；引流静脉和小静脉血管的显示 DSA 和 MRA-PC 法均优于 MRA-TOF 法,差异有统计学意义(χ2值/P 值 DSA? TOF-2.445/0.014、χ2值/P 值PC? TOF-3.443/0.001)；DSA 与 MRA-PC 法相比,差异无统计学意义(χ2值/P 值 DSA? PC-1.085/0.278)。结论MRA-TOF 法在显示脑动脉与 MRA-PC 法显示脑静脉方面与 DSA 基本一致,而MRA-TOF 和MRA-PC 法在显示动、静脉方面不能相互替代。

Objective To explore the clinical application value of MRA (TOF and PC)in cerebrovacular arteriovenous malforma-tion imaging when DAS as a reference gold standard.Methods 60 patients clinically suspected cerebral vascular malformations were enrolled in our study.They were all underwent MRA (TOF and PC)and DSA examinations successively within three days.Then, the imaging of feeding arteries,vascular malformation masses and venous drainages were compared and analyzed.Results Of all 60 patients with AVM,their feeding arteries and arterioles images were showed better by DSA and MRA-TOF technology than by MRA-PC.The difference was statistically significant (χ2/P DSA?PC - 4.1 75/0.000,χ2/P TOF ?PC - 3.508/0.000 ),no statistically difference was found between DSA and MRA-TOF findings,(χ2/P DSA?TOF -0.740/0.459).However,their venous drainages and venules show better with DSA and MRA-PC technology than with MRA-TOF method,the difference was statistically significant (χ2/P DSA?TOF -2.445/0.014,χ2/P PC?TOF -3.443/0.001),no statistically difference was found between DSA and MRA-PC findings (χ2/P DSA?PC -1.085/0.278).Conclusion MRA-TOF to display cerebral arteries and MRA-PC to show cerebral venues are basically consistent with the DSA,MRA-TOF and MRA-PC cannot replace each other when showing cerebral arteries and venous.
