由3名经验丰富的超声师对161例正常胰腺超声图像进行胰腺回声评价。超声检查根据胰腺的回声程度与肝脏的S回声程度进行比较，对胰腺回声程度进行分级。当胰腺与肝脏相等时为I级，II级略大于肝脏，III级明显大于肝脏，IV级时胰腺回声与腹膜后脂肪相同。胰腺回声与患者S年龄和皮下脂肪有关。计算机方法的统计分析表明，年龄和身体脂肪沉积都是回声增加的决定因素，而且它们独立发挥作用。给出了预期胰腺回声(PE)随年龄和皮下脂肪的变化公式：PE=0.788+(年龄)(0.021.+-)。0.003)+(皮肤厚度)(0.48.+-.0.08)。
Normal pancreatic sonograms of 161 patients were evaluated by 3 experienced sonographers for pancreatic echogenicity. Sonograms were given a grade for pancreatic echogenicity based on its echogenicity compared with the liver''s echogenicity. Grade I was given when the pancreas equaled the liver, grade II slightly greater than the liver, grade III definitely greater than the liver and grade IV when the pancreas was as echogenic as the retroperitoneal fat. Pancreatic echogenicity was correlated with the patient''s age and subcutaneous fat. Statistical analysis by computer methods indicated that both age and body fat deposition are determinants of increasing echogenicity and that they function independently. A formula is given for the expected pancreatic echogenicity (PE) as a function of age and subcutaneous fat: PE = 0.788 + (age)(0.021 .+-. 0.003) + (skin thickness)(0.48 .+-. 0.08).
