摘要
探讨实时剪切波弹性成像(Shear wave elastography,SWE)检测腮腺及颌下腺硬度的可行性,建立正常成人杨氏模量的参考值范围。方法:对820名健康成人进行腮腺及颌下腺实时剪切波弹性成像检查,比较左右两侧及不同性别、年龄组之间杨氏模量值的差异。结果:左右两侧腮腺及颌下腺杨氏模量值差异均无统计学意义(P>0.05)。不同性别间腮腺杨氏模量值差异有统计学意义(P<0.05);不同性别间颌下腺杨氏模量值差异无统计学意义(P>0.05)。不同年龄组的腮腺及颌下腺杨氏模量值差异均无统计学意义(P>0.05)。结论:实时剪切波弹性成像可用于评估腮腺及颌下腺的硬度,为疾病的鉴别诊断提供有价值的信息。
Objective： To explore the feasibility of detecting parotid gland and submaxillary gland＇s stiffness by shear wave elastography （SWE） and establish a reference range of Young＇s modulus in healthy adult. Methods： There were 820 healthy volunteers underwent SWE in parotid gland and submaxillary gland. The difference of Young＇s modulus in bilateral parotid and submaxillary gland, the values in different sex and age groups were also compared. Results： The differences of Young＇s modulus between two sides of parotid gland and submaxiUary gland has no statistically significant（P〉O.05）; the differ ences of Young＇s modulus of parotid gland between different sex groups has statistical significance （P〉O.05） but no statistical significance in submaxillary gland （P〉0.05）; The differences of Young＇s modulus in parotid gland and submaxillary gland be tween different age groups has no statistical significance （P〉0.05）. Conclusion： SWE can be successfully applied to assess parotid gland and submaxillary gland＇s stiffness and can provide valuable information for diagnosis.
