Three-dimensional (3D) body surface scanning offers a viable alternative for accurate breast volume calculation in surgical planning. This non-invasive method shows good patient tolerance and provides better spatial interpretation than traditional techniques.

Area of Science:

  • Medical Imaging
  • Surgical Planning
  • Biomedical Engineering

Background:

  • Accurate breast volume quantification is crucial for effective breast surgery, yet current methods are subjective and lack standardization.
  • Three-dimensional (3D) body surface imaging presents a novel approach to address these limitations in breast volume computation.

Purpose of the Study:

  • To compare the accuracy and reproducibility of breast volume calculations using 3D scanning against three established methods: MRI, thermoplastic castings, and anthropomorphic measurements.
  • To evaluate the relative advantages and disadvantages of each technique for clinical application.

Main Methods:

  • Breast volumes of six patients (n=12 breasts) were measured using a 3D laser scanner, MRI, thermoplastic castings, and anthropomorphic measurements.

  • Repeated measurements were performed to assess precision, with mean volumes, deviations, and regression analyses calculated.

    • Main Results:

    • MRI demonstrated the highest precision (1.56% mean deviation), followed by 3D scanning (2.27%), anthropomorphic measurements (6.26%), and thermoplastic castings (7.97%).
    • 3D scanning showed excellent agreement with MRI (r=0.990), superior to anthropomorphic measurements (r=0.947) and thermoplastic castings (r=0.727).

    Conclusions:

    • 3D body surface scanning provides acceptable accuracy and superior spatial interpretation compared to traditional methods, with non-invasiveness and good patient tolerance.
    • Further development of 3D scanning technology holds promise for enhancing preoperative planning and postoperative control in clinical breast surgery.
