目的利用64排螺旋CT重建方法测量统计成人胰腺的影像形态学数值,为影像学诊断及临床诊治提供解剖学影像资料。方法对168例成人进行64排螺旋CT下平扫加增强扫描后处理数据。统计测量胰腺体积、形态、胰腺与脾脏的关系。所得数值按年龄、性别进行分组统计处理并进行相关性分析。结果利用多平面重建、容积再现和最大密度投影等技术重建后,胰腺形态位置直观。胰腺平均体积(122±25)cm3,胰腺体积与年龄相关,男性组大于女性组(P<0.05)。轮廓光滑106例,分叶54例。胰尾与脾门紧贴者50例,占31.3%;分开者102例,占63.8%;胰尾越过脾门者8例,占5%。结论成人胰腺体积与年龄、性别相关,胰腺萎缩多发生于老年人,男性大于女性。64排螺旋CT可以作为解剖学手段,应用于成人胰腺及周围毗邻的形态学研究。
Objective To measure and measure the morphological values of adult pancreas using 64-slice spiral CT reconstruction method and provide anatomical imaging data for imaging diagnosis and clinical diagnosis and treatment. Methods 168 adult patients underwent 64-slice spiral CT enhanced scan post-processing data. Statistical analysis of pancreatic volume, morphology, the relationship between the pancreas and the spleen. The values obtained by age, gender, grouping and statistical processing and correlation analysis. Results Using multiplanar reconstruction, volume rendering and maximum density projection technology reconstruction, the pancreas morphological location intuitive. The mean volume of pancreas was (122 ± 25) cm3. The volume of pancreas was related to age. The male group was larger than the female group (P <0.05). Contour smooth 106 cases, 54 cases of lobulation. 50 cases of pancreatic tail and spleen door close, accounting for 31.3%; 102 cases were separated, accounting for 63.8%; 8 cases of pancreatic tail over the spleen door, accounting for 5%. Conclusion The volume of adult pancreas is related to age and gender. Pancreatic atrophy occurs more frequently in the elderly than in women. 64-slice spiral CT can be used as an anatomical method for the morphological study of the adjacent pancreas and its surroundings.
