It is for this reason that we would recommend implementing the Vectra 3D imaging technique for measurement of BCRL.Ask the doctor The need of the patient who wishes to be subjected to rhinoplasty, chin and other cosmetic procedures of the faceĪlways the patient’s issue during the discussion of any change in appearance was to be able to see the result before taking the “big decision”. By software automation, this technique could easily be integrated into clinical routine. Even though image processing is time consuming, 3D imaging combines high reproducibility with high precision. 3D imaging had a high intrarater reliability (Intraclass Correlation Coefficient = 0.999).Ĭonclusion: Results show that 3D imaging is an innovative method for measuring upper limb volume in BCRL patients. Bland–Altman plots showed a high limit of agreement between the single measurements. There was no significant difference between the two measurements for healthy arms ( p = 0.323) or BCRL arms ( p = 0.807) in 3D imaging. All measurements were performed twice by the same researcher to evaluate reliability. Slightly larger volumes were measured by the WD method in healthy arms (+9.8 mL p = 0.058) and also in BCRL arms (+18.5 mL p < 0.001). Methods and Results: Thirty-nine women with unilateral breast cancer-related lymphedema (BCRL) were included, of which 37 completed two volume measurement techniques (3D and WD) on the BCRL and contralateral healthy arm. The aim of this study is to determine the validity and reliability of 3D imaging by comparing it to the WD method in women with unilateral upper limb lymphedema. The high precision of three-dimensional (3D) imaging in comparison to WD has already been reported for healthy subjects.
A more precise and easy-to-use method would be favorable. For various reasons, however, the use of WD is restricted in clinical settings. Background: In the past, measurement of upper limb lymphedema was done by water displacement (WD), which is frequently cited as the gold standard.
