【摘要】 目的研究螺旋CT横断面上肠系膜上动、静脉与冠状线间夹角的测量在胰头疾病诊断中的意义。方法对行上腹部螺旋CT扫描的1127例成人,先确定冠状面为虚拟水平线,再对肠系膜上动、静脉连线与水平线间夹角予以测量分析。结果<60岁胰腺正常组成年人肠系膜上动、静脉水平夹角正常值范围为4.9°～34.7°;≥60岁胰腺正常组成年人肠系膜上动、静脉水平夹角正常值范围为-4.7°～17.3°;慢性胰腺炎组肠系膜上动、静脉水平夹角为-2.0°～17.6°;急性胰腺炎组肠系膜上动、静脉水平夹角为1.5°～48.5°;<60岁胰头恶性占位组肠系膜上动、静脉水平夹角为38.8°～42.8°;≥60岁组胰头恶性占位组肠系膜上动、静脉水平夹角为39.0°～53.6°。结论螺旋CT横断面上肠系膜上动、静脉与冠状线间夹角的测量对胰头病变的CT诊断具有一定的提示价值,是临床上诊断胰头病变的一种新思路。更多还原

【Abstract】 Objective To measure the angle between line of superior mesenteric artery and superior mesenteric vein with horizontal line by SCT and to explore its clinic significance. Methods From Feb. 2004 to Feb. 2006, 1127 adults were scanned by spiral CT. The coronal plane were definited as horizontal line, and then measured the angle between line of superior mesenteric artery and superior mesenteric vein with horizontal line by SCT. Results The range of angle were 4.9°～34.7° in normal adults whose age were less than 60; -4.7°～17.3°in normal adults whose age were more than 60;-2.0°～17.6°in chronic pancreatitis; 1.5°～48.5° in acute pancreatitis; 38.8°～42.8 ° in malignant pancreatic occupying lesion whose ages were less than 60; were 39.0°～53.6° in malignant pancreatic occupying lesion whose ages were more than 60. Conclusion The angle between line of superior mesenteric artery and superior mesenteric vein with horizontal line by SCT is useful to diagnosis the malignant pancreatic diseases.更多还原
