Background: Bioimpedance spectroscopy (BIS) devices are routinely used in the assessment of breast cancer-related lymphedema (BCRL). The equipotential electrode placement is a commonly used protocol for the assessment of BCRL. However, the sternal notch electrode placement protocol is also in use. Whether these two protocols are interchangeable is not known.

生物阻抗光谱设备在检测乳腺癌相关淋巴水肿时使用的两种电极放置协议的互换性

背景：生物阻抗谱 (BIS) 设备通常用于评估乳腺癌相关淋巴水肿 (BCRL)。等电位电极放置是评估 BCRL 的常用协议。然而，胸骨缺口电极放置协议也在使用中。这两种协议是否可以互换尚不得而知。
