心包窦、心包隐窝及心包间隙影像横断解剖

目的 了解心包腔在心脏、大血管周围形成的诸窦、隐窝、间隙,分析其横断解剖位置及其鉴别诊断。方法 本文搜集50例正常纵隔结构CT扫描病例,采用西门子螺旋CT Somatomplus。结果 心包横窦显示率100%,心包斜窦显示率84%,心包前下窦显示率100%,心包上隐窝显示率（主动脉前隐窝82%、主动脉后隐窝68%）,上腔静脉后隐窝显示率20%,左肺静脉隐窝显示率82%。结论 CT为横断扫描,具有很高的密度分辨率,能清晰显示纵隔正常结构,从而分析心包诸窦、隐窝、心包间隙的横断解剖及其鉴别诊断。

Dissection of the image of sinus, recess and clearance of pericardium

Objective In order to know the sinus, recess and clearance around heart and vasa formed by pericardium antrum. Methods This paper collected 50 cases of CT scannings using Siemens spiral CT Somatom Plus. Results It can be seen from these CT scannings that the display ratios of horizontal, slanting, front sinus and up recesses of pericardium including the front and back recesses of main artery, back recess of up antrum vein and recess of left lung vein is 100%, 84%, 100%, 82%, 68%, 20% and 82%, respectively. Conclusion It can therefore be concluded that the CT with the function of traverse scanning can clearly distinguish the normal configuration in length and breadth, whereby can analyze the dissection of sinus, recess and clearance of pericardium with diagnoses.
