摘　　要：目的使用双源CT(MDCT)心脏成像技术显示房间隔瘤(atrial septal aneurysm ASA),研究房间隔瘤瘤体大小、位置以及瘤体在不同心动周期的摆动情况,探讨双源CT心脏成像对房间隔瘤的诊断价值。方法回顾性分析17例采用西门子双源CT冠状动脉检查时偶然发现的ASA患者,通过多平面重建、多时相重组技术以及电影回放软件对ASA患者的影像进行观察,对瘤体基底宽度和最大垂直距离(长径)进行测量,对不同心动周期的瘤体摆动情况进行研究比较分析,并将双源CT心脏扫描的结果与经胸超声的结果进行对比分析。结果大小:瘤体最大垂直距离平均8.91±2.46 mm;瘤基底部宽度平均17.35±2.95 mm。位置:15例位于房间隔卵圆窝水平,2例累及全部房间隔。方向:9例房间隔瘤突向右心房,2例房间隔瘤突向左心房,6例左心房收缩期突向左心房,舒张期突向右心房。运动:9例房间隔瘤始终膨突向右心房,随着心动周期轻微摆动;2例房间隔瘤始终膨突向左心房,随着心动周期轻微摆动;6例房间隔瘤在两房之间随着心动周期摆动。合并症:所有患者左心房内和瘤体凹面未见血栓形成,5例合并房间隔缺损,12例未合并。结论MDCT心脏成像可以静态观察房间隔瘤发生的位置,瘤体的大小、长径、宽度:可以动态观察房间隔瘤在心动周期内的摆动情况,并可对临床潜在风险进行评估,可以作为ASA诊断的简单、快捷、实用、可靠的方法。Objective Double source CT(MDCT)cardiac imaging technique was used to display atrial septal tumor(atrial septal aneurysm ASA),to study the size and position of the CT and the swing of the tumor in different cardiac cycles,and to explore the diagnosis of atrial septal aneurysm with double source cardiac imaging.Methods A retrospective analysis of 17 ASA patients accidentally discovered during coronary angiography with SIEMENS quantum dual source CT.The images of ASA patients were observed by multiplanar reconstruction(MPR),multitemporal reconstruction(MPR)and film playback software.The base width and maximum vertical distance(length and diameter)of the tumor were measured.The swing of the tumor in different cardiac cycles was studied and compared.The results of dual source CT cardiac imaging were compared with those of transthoracic echocardiography.Results Size:The maximum vertical distance between the large and small tumors averaged 8.91±2.46 mm.The average width of the base of the tumor was 17.35±2.95 mm.Site:15 cases were located at the level of oval fossa of interatrial septum,2 cases involved all interatrial septum.Direction:Atrial septal aneurysm protruded to right atrium in 9 cases and to left atrium in 2 cases.In 6 cases,the left atrium was convex to the left atrium in systolic phase and to the right atrium in diastolic phase.Wobble:Atrial septal aneurysm(ASA)always swelled to the right atrium in 9 cases and swayed slightly with the cardiac cycle.In 2 cases,the aneurysm of atrial septum always swelled to the left atrium and swayed slightly with the cardiac cycle.In 5 cases,the atrial septal aneurysm oscillated between the two chambers of the heart.Complication:No thrombosis was found in the left atrium and the concave surface of the tumor in all patients.5 cases were complicated with atrial septal defect and 12 cases were not.Conclusion MDCT cardiac imaging can be used to observe the location,size,length and width of atrial septal aneurysm under static condition,to observe the swing of atrial septal ane
