Abstract:

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 55mm to 13mm 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.
