摘要:
目的 探讨静息态下正常人左心室各节段CT心肌灌注的差异性。方法 对57例冠状动脉CT血管成像显示无狭窄的受检者行动态CT心肌灌注扫描分析,采用17节段标准分段方法(排除心尖),记录各节段心肌血流量(MBF)和心肌血容量(MBV),并进行同层面或不同层面间的比较。结果 前壁MBF和MBV值分别为(82.6±14.23)mL/(100 mL·min)和(10.51±1.66)mL/100 mL; 侧壁MBF和MBV值分别为(87.8±14.36)mL/(100 mL·min)和(11.54±1.47)mL/100 mL。高于室间隔[MBF(77.3±15.06)mL/(100 mL·min)和MBV(10.4±1.60)mL/100 mL]及下壁[MBF(75.83±14.48)mL/(100 mL·min)和MBV(9.85±1.24)mL/100 mL](P<0.05)。在4个心肌壁中,前壁基底段MBF低于中间段和心尖段(P<0.05)。下壁基底段MBF低于心尖段(P<0.05),略低于中间段(P=0.085)。侧壁基底段MBF低于中间段和心尖段,但节段之间比较的差异无统计学意义(P>0.05)。结论 对于健康人群左心室各节段的灌注存在差异,侧壁和前壁MBF及MBV高于室间隔和下壁,其中侧壁最高,下壁最低; 各壁的基底段灌注值较低。
Abstract:
Objective To investigate whether there are differences in perfusion in each segment of the left ventricle of normal people at rest.Methods A total of 57 cases of coronary artery CT angiography showed no stenosis underwent dynamic CT myocardial perfusion scan analysis,using the 17-segment standard segmentation method(excluding the apex),recording each segmental myocardial blood flow(MBF)and myocardial blood volume(MBV), and compare the same level or different levels.Results The anterior wall MBF and MBV values were(82.6±14.23)mL/(100 mL·min)and(10.51±1.66)mL/100 mL,respectively;the lateral wall MBF and MBV values were(87.8±14.36)mL/(100 mL·min)and(11.54±1.47)mL/100 mL,respectively,high in the interventricular septum[MBF(77.3±15.06)mL/(100 mL·min)and MBV(10.4±1.60)mL/100 mL] and inferior wall [MBF(75.83±14.48)mL/(100 mL·min)and MBV(9.85±1.24)mL/100 mL](P<0.05).Among the four myocardial walls,the MBF of the anterior basal segment was lower than the middle and apical segments(P<0.05).The MBF of the inferior basal segment was lower than the apical segment(P<0.05),and slightly lower than the middle segment(P=0.085).The MBF of the lateral basal segment was lower than that of the middle and apical segments,but there was no significant difference between the segments(P>0.05).Conclusion There are differences in the perfusion of each segment of the left ventricle in healthy people.The MBF and MBV of the sidewall and anterior wall are higher than the septum and the inferior wall.The lateral wall is the highest and the inferior wall is the lowest.The perfusion value of the basal segment of each wall is lower.
