Summary
This study shows the X'TENS range extender significantly reduces radiation dose to the operator's hand during vertebroplasty. Proper use is crucial for effective radioprotection in fluoroscopy procedures.
Area of Science:
- Medical Physics
- Interventional Radiology
Background:
- Radioprotection for operators during fluoroscopy is a significant concern.
- The X'TENS range extender is a novel device designed to reduce operator radiation exposure.
Purpose of the Study:
- To evaluate the effectiveness of the X'TENS range extender in reducing radiation dose to the operator's hand.
- To provide performance data for this new radioprotective device.
Main Methods:
- A prospective clinical study involving 14 interventions and 20 vertebrae.
- Radiation dose to the operator's hand was measured with and without the X'TENS device using a UNFOR Instrument sensor.
- Data were analyzed using the Wilcoxon matched pairs test.
Main Results:
- The dose to the hand per ml injected was significantly lower with the X'TENS device (111.37) compared to without (166.91) (p<0.05).
- Average injection time showed no significant difference between procedures (p=0.75).
- Results align with the inverse-square law, indicating device effectiveness is dependent on its length and proper usage.
Conclusions:
- The X'TENS range extender effectively reduces operator hand radiation dose during vertebroplasty.
- Rigorous and correct application of the device is essential for optimal radioprotection.
- Findings contribute to safer practices in interventional radiology procedures.
