Summary
Magnetic Resonance Imaging (MRI) enhances minimally invasive procedures by guiding interventions. Further development is needed for accessible MRI systems and compatible instruments for interventional applications.
Area of Science:
- Medical Imaging
- Interventional Radiology
- Minimally Invasive Surgery
Background:
- Magnetic Resonance Imaging (MRI) offers significant advantages for guiding, monitoring, and controlling diagnostic and therapeutic interventions.
- MRI is particularly valuable for minimally invasive and minimal access surgical approaches.
- Its role is prominent in monitoring interstitial ablative procedures like thermal therapy, cryosurgery, and focused ultrasound surgery.
Purpose of the Study:
- To highlight the advantages of MRI in interventional procedures.
- To identify requirements for effective MR-guided interventions.
- To address challenges in implementing interventional MRI.
Main Methods:
- Review of current MRI capabilities in interventional settings.
- Discussion of pulse sequence requirements for dynamic imaging.
- Consideration of magnet configurations and instrument compatibility.
Main Results:
- MRI excels in monitoring and controlling interstitial ablative therapies.
- Effective MR monitoring requires optimized pulse sequences for spatial/temporal resolution and image quality.
- Accessible magnet configurations and MR-compatible instruments are crucial.
Conclusions:
- MRI is a powerful tool for guiding and monitoring minimally invasive interventions.
- Advancements in accessible MRI systems and device compatibility are essential for broader clinical adoption.
- Integration of therapy delivery with MR systems requires further attention.
