Summary
Active biplanar MR needle tracking shows promise for clinical use. This technique, utilizing an integrated signal source, was successfully evaluated in patient procedures on a 0.5-T open MRI system.
Area of Science:
- Medical Imaging
- Interventional Radiology
Background:
- Minimally invasive procedures require precise instrument navigation.
- Magnetic Resonance (MR) imaging offers excellent soft-tissue contrast for guidance.
Purpose of the Study:
- To assess the feasibility of active biplanar MR needle tracking.
- To evaluate a novel needle with an integrated signal source.
- To test the technique in both in vitro and in vivo settings.
Main Methods:
- Utilized a 0.5-T open-configuration MR system.
- Employed a specially designed needle with an internal signal source.
- Performed procedures on patients for in vivo evaluation.
Main Results:
- Demonstrated successful biplanar MR needle tracking.
- Confirmed the technique's applicability in a clinical setting.
- Showcased the benefit of an integrated signal source for tracking.
Conclusions:
- Active biplanar MR needle tracking is viable for clinical application.
- The integrated signal source significantly enhances tracking capabilities.
- This technology holds potential for improving interventional MR procedures.
