简介：本研究的目的是评估超声剪切波弹性成像（SSWE）在诊断非恶性肾上腺肿块中的可行性和有用性。材料和方法：本研究纳入了 13 名患者，总共 16 个肾上腺肿块。在每种情况下，均进行了传统超声成像和 SSWE 进行刚度评估。最终诊断基于CT、MRI、生化检查、手术或一年以上的随访。结果：最终诊断：6个肿块结节性增生、6个腺瘤、3个囊肿和1个髓脂肪瘤。所有实性肾上腺肿块均呈现弹性成像信号，与没有弹性成像信号的囊性病变形成对比，因为剪切波不通过液体传播。结论：SSWE 是一种可行的技术，可在腹部和腹膜后超声检查期间应用。 SSWE 具有区分实性和囊性肾上腺病变的潜力。有必要进行进一步的大规模研究，评估 SSWE 区分肾上腺和其他腹膜后肿块的可能性。
Introduction: The aim of this study was to evaluate the feasibility and usefulness of supersonic shear wave elastography (SSWE) in the diagnosis of nonmalignant adrenal masses.Material and methods: 13 patients with a total number of 16 adrenal masses were enrolled in the study. In each case, both conventional ultrasound imaging and SSWE for stiffness assessment were performed. The final diagnosis was based on CT, MRI, biochemical studies, surgery or more than one year of follow up.Results: The final diagnosis: nodular hyperplasia in six masses, six adenomas, three cysts, and one myelolipoma. All solid adrenal masses presented the elastography signal in contrast to cystic lesions that were devoid of it, as shear waves do not propagate through fluids.Conclusions: SSWE is a feasible technique that can be applied during ultrasound of the abdomen and retroperitoneum. SSWE presents potential for the differentiation of solid and cystic adrenal lesions. Further large scale studies evaluating the possibility of differentiation of adrenal and other retroperitoneal masses with SSWE are warranted.
