磁共振血管成像定量研究脑后循环缺血患者的功能性后交通动脉的血流动力学特征

目的 研究脑后循环缺血(PCI)患者功能性后交通动脉(F-PCoA)定量分析中磁共振血管成像(MRA)的应用价值.方法 采用回顾性分析方法,研究对象为2019年1月至2020年1月沧州中西医结合医院收治入院的63例行MRA检查者,根据是否存在PCI分为PCI组(n=32)和非PCI组(n=31),且非PCI组根据是否存...

Magnetic resonance angiography quantitative study on the hemodynamic characteristics of functional posterior communication artery in patients with posterior cerebral circulation ischemia

Objective To study the application value of functional Posterior communication(PCI)in quantitative analysis of magnetic resonance angiography(MRA)in functional posterior cerebral ischemia(F-PCOA).Methods Using a retrospective analysis method,the subjects of the study were 63 routine MRA examiners admitted to Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine from January 2019 to January 2020,and were divided into PCI group(n=32)and non-PCI group(n=31)according to whether there was PCI.And the non-PCI group was divided into F-PCoA group(n=13)and no F-PCoA group(n=18)according to whether there was F-PCoA.The results of functional posterior communicating artery MRA examinations between the PCI group and the F-PCOA group(the F-PCoA front and back absolute sub-flow,cross-sectional area,average flow velocity,and average flow)were observed and compared;at the same time,The F-PCOA group with Basilar artery MRA inspection results without F-PCOA group(peak flow rate,peak flow rate,maximum flow rate,minimum flow rate,average flow rate,maximum flow rate,minimum flow rate,average flow rate,cross-sectional area)were observed and compared.Results There was no significant difference between the PCI group and the F-PCOA group of F-PCoA front and back absolute sub-flow,cross-sectional area,average flow rate,and average flow rate(P>0.05).There was no significant difference between the F-PCOA group and the non-F-PCOA group in flow peak height,flow peak height,maximum flow rate,minimum flow rate,average flow rate,maximum flow rate,minimum flow rate and average flow rate(P>0.05);F-PCOA The cross-sectional area of the group was significantly smaller than that of the group without F-PCOA,the difference was statistically significant(P<0.05).Conclusion The application effect of MRA in the quantitative analysis of F-PCoA in PCI patients is significant,and the forward and backward absolute shunt of F-PCoA can provide reference for clinical diagnosis and treatment of PCI.
