A novel dual-array ultrasound probe allows for in-plane needle visualization during thoracic and lumbar facet joint injections. This technology shows promise for improving procedural accuracy, though a learning curve exists.
Area of Science:
- Medical Imaging
- Interventional Pain Management
- Ultrasound Technology
Background:
- Ultrasound-guided neuraxial injections often lack accuracy compared to fluoroscopy due to poor needle visualization, especially with out-of-plane approaches.
- A new dual-array ultrasound probe facilitates in-plane needle visualization, even for perpendicular insertions.
- This study investigates the accuracy of this novel ultrasound probe for thoracic and lumbar facet joint injections.
