自从CT问世以来,很快就成为我们诊断胰腺包块的一种不可缺少的工具。它不但能帮助我们明确包块的形状、密度、血供,还能提供包块周围及其胰腺组织的变化情况。髓着CT检查结果的普及,正确分析CT检查结果,就成为我们每个临床医生面临的一个重要向题。现就多种胰腺包块的CT表现进行以下评述。正常胰腺正常胰腺外形狭长,位于腹膜后,横跨第1~2腰椎,分头、颈、体、尾四部分。胰头最低,胰尾最高。其头、体、尾三部分的横断面宽度分别为3~4cm、2~3cm、1~2cm,胰头部最宽,位于十二指肠降部内侧,横断面为圆形,其下方的钩突为三角形,尖端向左,在肠系膜上动脉及上静脉的右后方,与左肾静脉位于同一水平。胰体为弓形,凸面向前,其背侧有肠
Since the advent of CT, it has quickly become an indispensable tool for us to diagnose pancreatic masses. It not only helps us to define the shape, density, and blood supply of the mass, but also provides changes in the mass around the mass and in the pancreas. The popularity of CT scans and accurate analysis of CT findings have become an important issue for each of our clinicians. The following review is performed on CT manifestations of various pancreatic masses. Normal pancreas normal pancreas shape is narrow, located behind the retroperitoneum, across the first to 2 lumbar vertebrae, head, neck, body, tail four parts. The head of the pancreas is the lowest and the pancreas tail is the highest The cross-sectional widths of the head, body, and tail were 3 to 4 cm, 2 to 3 cm, and 1 to 2 cm, respectively. The pancreatic head was the widest and was located inside the descending portion of the duodenum. The cross-section was circular and below it. The uncinate process is triangular, with the tip pointing to the left, at the right of the superior mesenteric artery and the superior vein, and at the same level as the left renal vein. The body of the pancreas is bow-shaped, with its convex surface facing forward, and its dorsal side has an intestine
