Conventional laparoscopy lacks 3D views. An open-configured MRI system enables minimally invasive procedures with MR-guidance, combining surgical benefits with MRI

Area of Science:

Medical Imaging
Minimally Invasive Surgery
Interventional Radiology

Context:

Conventional laparoscopy offers limited 3D visualization, hindering surgical precision.
Minimally invasive surgery (MIS) aims to reduce patient trauma but often lacks advanced imaging.
Magnetic Resonance (MR) imaging provides superior soft-tissue contrast and temperature sensitivity.

Purpose:

To introduce an open-configured 0.5 Tesla MR-imaging system designed for intraoperative guidance.
To evaluate the feasibility of performing minimally invasive procedures under MR-guidance.
To explore the diagnostic and therapeutic potential of MR-guided interventions, particularly for inoperable metastases.

Summary:

An open-configured MR-imaging system (0.5 Tesla, GE) provides unimpeded patient access for MR-guided minimally invasive procedures.

This approach integrates the benefits of MIS with the detailed tissue visualization and thermal sensitivity of MR imaging.

The system facilitates both diagnostic evaluations and therapeutic interventions, including interstitial therapy for parenchymal organ metastases.

Impact:

Enhances surgical precision through true 3D visualization, overcoming a key limitation of conventional laparoscopy.
Enables novel MR-guided interventional therapies, expanding treatment options for challenging conditions like inoperable metastases.
Paves the way for combining the advantages of minimally invasive approaches with the diagnostic power of advanced MR imaging.
