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 a practical morphological basis for the diagnosis and surgical treatment of pancreatic lesions. Methods The sections, adjacent and size of the pancreas in two consecutive adult patients with upper abdomen coronal CT and 86 healthy adults with MSCT images were studied. Results The pancreas was concentrated in the continuous coronal plane 55 mm anterior to the trailing edge of the inferior vena cava and 13 mm thereafter. The landmark level: the superior mesenteric vein level, the main hepatic portal vein level, the former by the inferior vena cava and left renal vein layer, the inferior vena cava after the copy and aortic hiatus level. The maximum upper and lower diameter and left and right diameter of pancreas neck, pancreas head, pancreas and pancreas at the corresponding level were (21.63 ± 3.62), (11.06 ± 2.33) mm, (47.56 ± 6.47) and (36.55 ± 6.69) mm, respectively ± 5.32), (52.29 ± 10.80) mm, (22.16 ± 2.07) and (35.14 ± 6.06) mm, respectively. Conclusions Coronal CT images of pancreas can be used in clinical diagnosis and make up for the limitations of transverse CT images showing lesions.
