Summary
This study shows that a real-time 3D virtual reality navigation system with open MRI is a safe and effective tool for excising nonpalpable breast tumors. Further research is needed to assess long-term outcomes.
Area of Science:
- Medical Imaging
- Surgical Navigation
- Virtual Reality
Background:
- Breast-conserving surgery aims for accurate tumor removal.
- Nonpalpable, MRI-detected breast tumors present excision challenges.
Purpose of the Study:
- To evaluate early experiences with a real-time 3D virtual reality navigation system integrated with open MRI for breast cancer surgery.
Main Methods:
- A 3D virtual reality navigation system was developed and tested using a 3D phantom.
- Two patients with nonpalpable tumors underwent surgery guided by the system.
- The system generated a 3D model for guiding tumor excision and dye marker placement.
Main Results:
- The navigation system demonstrated a mean mismatch of 2.01 mm with real distance in phantom tests.
- Tumor excision and dye marker placement were successfully performed in both patients.
- Histopathological analysis confirmed clear surgical margins in both cases.
Conclusions:
- The real-time 3D virtual reality navigation system with open MRI is feasible for precise excision of nonpalpable breast tumors.
- The technique shows promise for safe and accurate breast-conserving surgery.
