Summary
Augmented reality navigation systems enhance percutaneous CT-guided lung biopsies, reducing procedure time and radiation exposure. This technology proves safe and effective for improving diagnostic accuracy and efficiency.
Area of Science:
- Medical imaging and interventional radiology
- Surgical navigation systems
- Computer-assisted surgery
Background:
- Augmented reality (AR) integrates real-time imaging with virtual data for enhanced visualization.
- Percutaneous CT-guided lung biopsies are crucial for diagnosing lung lesions.
- Traditional methods may face challenges in accuracy and efficiency.
Purpose of the Study:
- To verify the accuracy and clinical utility of an AR navigation system for percutaneous CT-guided lung biopsies.
- To compare the outcomes of AR-assisted biopsies with traditional CT-guided procedures.
Main Methods:
- A comparative study involving 180 patients with solitary lung lesions.
- Patients were divided into two groups: traditional CT-guided biopsy (Group C, 90 patients) and AR navigation system-assisted biopsy (Group S, 90 patients).
- Key metrics recorded included procedure time, CT scans, radiation dose, and complications.
Main Results:
- Successful pathological diagnosis was achieved in 96% of AR-assisted cases versus 90% in traditional cases.
- AR navigation significantly reduced procedure time, CT scans, and radiation dose (P <0.001).
- Complication rates were comparable: 14% for AR-assisted and 17% for traditional procedures.
Conclusions:
- The AR navigation system is a safe, reliable, and effective tool for percutaneous CT-guided lung biopsies.
- It shortens procedure time, reduces radiation exposure, and lowers the rate of insufficient specimens.
- AR technology has the potential to increase procedure throughput without increasing complications.
