Summary
Magnetic Resonance (MR) imaging guides abdominal interventions like biopsies and tumor ablations. New MR techniques also monitor ablation and drain fluid collections, aiding difficult-to-locate lesions.
Area of Science:
- Medical Imaging
- Interventional Radiology
- Oncology
Background:
- Abdominal interventions require precise guidance for optimal outcomes.
- Magnetic Resonance (MR) imaging offers unique soft-tissue contrast for lesion localization.
- Advancements in MR technology enable real-time monitoring of interventional procedures.
Purpose of the Study:
- To provide an overview of current abdominal interventional applications guided by MR imaging.
- To highlight the role of MR imaging in diagnostic biopsies, tumor ablations, and fluid management.
- To discuss the benefits of MR guidance for challenging lesion localizations.
Main Methods:
- Review of current MR-guided abdominal interventional techniques.
- Discussion of new pulse sequences for enhanced monitoring.
- Case examples illustrating optimal patient selection.
Main Results:
- MR imaging is effective for guiding diagnostic biopsies and tumor ablations.
- Advanced MR pulse sequences allow real-time monitoring of ablation processes.
- MR guidance facilitates aspiration and drainage of fluid collections.
Conclusions:
- MR imaging is a valuable tool for a range of abdominal interventional procedures.
- MR guidance is particularly beneficial for lesions difficult to localize or in suboptimal positions.
- Ongoing technological advancements continue to expand the utility of MR in interventional radiology.
