Vectra 3D Imaging for Upper Limb Lymphedema: Author Response | Dr. Daniel Gould

Dr. Daniel Gould co-authored this response published in Plastic and Reconstructive Surgery, continuing the scientific discussion surrounding the use of Vectra three-dimensional imaging to measure upper limb volume in patients with lymphedema.

The response follows the team’s earlier feasibility study exploring Vectra 3D imaging as a noninvasive method for evaluating changes in arm volume. Accurate measurement is particularly important in lymphedema care, where clinicians need reliable ways to assess disease progression and response to treatment.

Dr. Gould and his co-authors address questions surrounding how different volumetric measurement techniques compare. They note that variation between methods and user-related differences can make measurements difficult to interchange, reinforcing the need for standardized and reproducible approaches.

The authors also discuss ways to improve consistency when using three-dimensional imaging, including establishing standardized anatomical reference points. As imaging technology develops, greater measurement precision may allow clinicians and researchers to identify subtle changes and more accurately track long-term treatment outcomes.

The response reinforces the potential role of 3D imaging in lymphedema assessment while recognizing that further research is needed to determine how these technologies compare with established measurement techniques.
