摘　　要：目的为胰腺病变的断层影像诊断和外科治疗提供实用的形态学依据。方法研究2例成人上腹部连续冠状断层标本和86例健康成人上腹部多层螺旋CT(MSCT)冠状位图像上胰腺的分部、毗邻和大小。结果胰腺在连续冠状断层上集中出现在下腔静脉后缘前55 mm和其后13 mm的范围内。标志性层面为:经肠系膜上静脉层面、经肝门静脉主干层面、经下腔静脉前份及左肾静脉层面、经下腔静脉后份和主动脉裂孔层面。相应层面胰颈、胰头、胰体、胰尾的最大上下径和左右径分别为(21.63±3.62)、(11.06±2.33)mm,(47.56±6.47)、(36.55±6.69)mm,(30.13±5.32)、(52.29±10.80)mm,(22.16±2.07)、(35.14±6.06)mm。结论胰腺MSCT冠状位图像可应用于临床诊断,弥补了横断位CT图像显示病变的局限性。Objective To provide practical anatomic data for the imaging diagnosis and surgical treatment of the disease of pancreas.Methods The division,adjoin and size of pancreas on the coronal plane were investigated on 2 sets of serial coronal sections of superior abdomen of Chinese adult cadavers,multi-spiral computed tomography（MSCT） imaging of 86 superior abdomen of Chinese adult healthy volunteers.Results The pancreas was visualized mainly on the serial coronal sections ranging from 55 mm to 13 mm before and after the posterior margin of inferior vena cava respectively.The representative section was the section through the superior mesenteric vein,the section through the trunk of hepatic portal vein,the section through the anterior part of inferior vena cava and left renal vein,the section through the anterior part of inferior vena cava and left renal vein,the section through the posterior part of inferior vena cava and aortic hiatus.The left and right dimensions of pancreas were（21.63±3.62）mm and（11.06±2.33）mm;（47.56±6.47）mm and（36.55±6.69）mm;（30.13±5.32）mm and（52.29±10.80）;（22.16±2.07）mm and（35.14±6.06）mm respectively.Conclusion Coronary MSCT images can be used for diagnosis,which make up for the Deficiency of transversal CTimages.
