Background: Early diagnosis of mild lymphedema and treatment are important to prevent its progress. The tissue dielectric constant (TDC), measuring local tissue water in the skin and upper subcutis, has neither been related to the water displacement method (WDM) nor been used to diagnose mild arm lymphedema in patients at risk. Our aims were to evaluate TDC and WDM in combination with palpation, examine the association between TDC and WDM measurements, and compare lymphedema-related factors.

皮肤和皮下厚度增加的触诊、组织介电常数和水置换法用于诊断早期轻度手臂淋巴水肿。

背景：轻度淋巴水肿的早期诊断和治疗对于防止其进展很重要。测量皮肤和上皮下组织局部组织水分的组织介电常数 (TDC) 既与水置换法 (WDM) 无关，也未用于诊断高危患者的轻度手臂淋巴水肿。我们的目标是结合触诊评估 TDC 和 WDM，检查 TDC 和 WDM 测量值之间的关联，并比较淋巴水肿相关因素。
