摘要
目的结合横、冠、矢状面解剖尸体标本,采用16层螺旋 CT(MSCT)三维(3D)重组技术,评价心包窦、隐窝积液的 CT 表现特征及其影像学意义。方法观察横、冠、矢状面尸体标本各1具的心包窦、隐窝的解剖及其通连关系,以及104例心包窦、隐窝积液患者的16层 MSCT 影像学表现特征,并对积液的显示率进行分析。结果 3具断面尸体标本以及 MSCT 图像均显示心包窦、隐窝系心包脏、壁两层在出入心脏大血管的根部相互移行而形成的腔隙。心包少量积液组与中至大量积液各组心包窦、隐窝积液的显示率差异有统计学意义(P<0.05)。心包积液易积聚于主动脉上隐窝。结论 MSCT 3D 重组技术能直观、立体地显示心包窦、隐窝积液的形态学特征以及与固有心包腔的直接通连关系,能有效地与纵隔或心包内其他病变相鉴别。
Objective To evaluate the CT features and implications of the pericardial sinuses and recesses effusion by combining the sectional cadavers and 16 multi-slice CT （MSCT） reformation. Methods The anatomy and communication of the pericardial sinuses and recesses on the axial, coronal and saggital sectional cadavers （respectively 1 case）, and the morphologic features on MSCT reformatted images in 104 patients were observed. The detection rate of effusion was analyzed. Results The sectional cadavers and CT images showed that the perieardial sinuses and recesses were formed by the reflections of the pericardium on the root of the great vessels. The detection rate of the sinuses and recesses was lower in small effusion than in moderate and large effusion （ P 〈 0. 05 ）. The superior aortic recess was the most common recess for pericardial effusion. Conclusion The MSCT reformatted images can show the morphologic features of pericardial sinuses and recesses effusion and communications with the pericardial cavity, help differentiate pericardial effusion from other mediastinal or pericardial lesions.
