Lymph edema of the arm is a common complication after breast cancer treatment. To evaluate lymph edema volume and treatment outcome, an easy to use, objective quantification method of arm volume is necessary. Most often, water displacement is used to measure arm volume, as it is an easy and robust method that can be performed at any place with a simple equipment. However, when using water displacement, no exact localization of volume difference can be seen. To accurately measure hand and forearm volumes separately, an in-house-developed device was constructed for an accurate landmark placement.
An in-house developed measurement tool was used for placing artificial landmarks proximal to the wrist crease on ten healthy subjects. Three-dimensional (3D) images of the hand and forearm were acquired, and volume measurements of the hand and forearm were performed. Measurements were repeated to investigate the intra- and inter-rater variability caused by the landmark placement.
Measuring volume of the hand and forearm while using artificially placed landmarks turned out to be a highly reproducible, quick, and easy procedure. Both intra- and inter-rater variability showed high reproducibility for hand (ICC = 0.96 and 0.98, respectively) and forearm (ICC = 0.99 and 0.99, respectively) volumes.

手臂淋巴水肿是乳腺癌治疗后的常见并发症。为了评估淋巴水肿的体积和治疗效果，需要一种易于使用的客观手臂体积量化方法。最常用的是排水法来测量手臂体积，因为它是一种简单且可靠的方法，可在任何地方使用简单设备进行操作。然而，使用排水法时，无法看到体积差异的确切定位。为了分别准确测量手部和前臂的体积，我们制作了一种自行研发的装置，用于精确地标放置。
使用自行研发的测量工具在十名健康受试者的手腕褶皱近端放置人工地标。获取手部和前臂的三维（3D）图像，并对手部和前臂进行体积测量。重复测量以研究地标放置引起的评分者内和评分者间的变异性。
使用人工放置的地标测量手部和前臂的体积是一种高度可重复、快速且简单的程序。评分者内和评分者间的变异性对手部（ICC分别为0.96和0.98）和前臂（ICC分别为0.99和0.99）的体积均显示出高重复性。
