Summary
Magnetic resonance imaging (MRI) accurately measures silicone breast implant volumes using various software. This technology aids in surgical planning and objective assessment of breast augmentation results.
Area of Science:
- Plastic Surgery
- Medical Imaging
- Radiology
Background:
- Lipofilling and silicone implant augmentation are increasingly common in breast plastic surgery.
- Accurate assessment of breast volume is crucial for controlling postoperative outcomes.
- Magnetic resonance imaging (MRI) is utilized for evaluating breast volume post-surgery.
Purpose of the Study:
- To evaluate the accuracy of MRI-based breast volumetry software tools.
- To compare MRI-derived measurements of augmented breasts with actual silicone implant volumes.
- To assess the reliability of different software programs for breast implant volumetry.
Main Methods:
- MRI-based volume analysis was conducted on eight bilaterally augmented patients.
- Three software programs were used: Brainlab©, Medis©, and OsiriX©.
- Measurements were compared against manufacturer-specified silicone implant volumes.
Main Results:
- All tested software demonstrated high accuracy in measuring silicone implant volumes.
- Mean deviations ranged from 2.2% (Brainlab©) to 3.1% (Medis©).
- High correlation (r=0.99) was observed between MRI-derived and actual implant volumes.
Conclusions:
- MRI-based volumetry is a reliable tool for calculating native breast and silicone implant volumes.
- The evaluated software solutions (Brainlab©, Medis©, OsiriX©) performed well in accuracy and speed.
- MRI breast volumetry can assist in surgical planning, determining implant size, and objectively assessing postoperative results.
