The use of ultrasound (US) elastography to assess the pancreas is subject to serious limitations, and it is not easy to perform US elastography for the pancreas with satisfactory and reproducible accuracy. The aim of our study was to show the normal pancreatic stiffness values with shear wave elastography (SWE) and to evaluate the pancreatic tissue stiffness at two different respiratory phases.
Sixty-three subjects were included in the study. Median values of pancreatic stiffness were recorded. Values during deep inspiration and free breathing were compared.
The stiffness values of the pancreatic tissue measured during deep inspiration breath holds and during free breathing were 5.70 ± 1.74 kPa and 4.15 ± 1.70 kPa, respectively. It was found that the values of pancreatic tissue stiffness measured during deep inspiration were statistically significantly higher than those measured during physiological breathing (p < 0.001).
Because of the reference value differences between different ultrasound elastography devices, it is important to know the reference ranges of normal pancreatic stiffness according to the device, in order to distinguish possible pathologies. In addition, the variability of pancreatic stiffness measurements with respiratory phases should be considered in clinical applications.
超声弹性成像（US）评估胰腺受到严重限制，并且不容易对胰腺进行具有满意和可重复准确性的 US 弹性成像。我们的研究旨在通过剪切波弹性成像（SWE）显示正常胰腺的弹性值，并评估在两个不同呼吸阶段的胰腺组织的硬度。
共纳入 63 名受试者。记录胰腺硬度的中位数。比较深吸气和自由呼吸时的数值。
深吸气呼吸暂停和自由呼吸时胰腺组织的弹性值分别为 5.70±1.74 kPa 和 4.15±1.70 kPa。发现深吸气时测量的胰腺组织硬度值明显高于生理呼吸时测量的值（p<0.001）。
由于不同超声弹性成像设备之间的参考值差异，根据设备了解正常胰腺硬度的参考范围以区分可能的病变非常重要。此外，在临床应用中应考虑呼吸阶段对胰腺硬度测量的可变性。
