Summary
The bone cement injector significantly reduced radiation exposure for physicians during percutaneous vertebroplasty compared to a standard syringe. This finding highlights a safer method for interventional procedures.
Area of Science:
- Interventional radiology
- Medical physics
- Radiation safety
Background:
- Percutaneous vertebroplasty (PV) is an interventional procedure requiring fluoroscopic guidance.
- Physician radiation exposure during PV can be significant, necessitating methods to reduce dose.
- Evaluating different injection devices is crucial for optimizing radiation safety in PV.
Purpose of the Study:
- To quantify and compare physician radiation doses during PV using two distinct injection devices.
- To assess radiation exposure with computed tomography (CT) and an angiographic/CT system.
Main Methods:
- Twenty patients undergoing PV were divided into two groups: 1-mL syringe and bone cement injector.
- Radiation doses (Ha, Hb, HE) were measured using electronic personal dosimeters worn by operators.
- Procedures were performed using an integrated angiographic/CT system (IVR-CT).
Main Results:
- The bone cement injector group showed significantly lower mean doses (Ha, Hb, HE) compared to the 1-mL syringe group.
- Mean Ha: 116.2 microSv (injector) vs. 320.8 microSv (syringe).
- Mean HE: 19.7 microSv (injector) vs. 48.2 microSv (syringe), with no significant difference in fluoroscopy time.
Conclusions:
- Physician radiation exposure during PV is substantial.
- The bone cement injector is effective in reducing operator radiation exposure during PV.
- This device offers a practical solution for enhancing radiation safety in PV procedures.
