White Paper: Interventional MRI: Current Status and Potential for Development Considering Economic Perspectives, Part...

Area of Science:

• Medical Imaging and Interventional Radiology
• Minimally Invasive Procedures
• Cardiovascular Interventions

Background:

• Magnetic resonance imaging (MRI) offers superior soft tissue contrast and physiological parameter measurement (e.g., flow, cardiac function), making it attractive for guiding and monitoring interventional procedures.
• The development of MR-safe monitoring systems and instruments has historically limited interventional MRI (iMRI) to procedures not feasible with other modalities.

Purpose of the Study:

• To analyze the current status and clinical routine application of interventional MRI.
• To assess the potential for broader future application of iMRI based on its advantages.

Main Methods:

• Analysis of the current clinical status of interventional MRI procedures.
• Review of established and emerging applications of MRI-guided interventions.

Main Results:

• Interventional MRI is established for specific indications, including breast and prostate biopsies, and cardiovascular interventions like atrial fibrillation ablation.
• MR-guided biopsies are replacing traditional methods, often enhanced by image fusion techniques (e.g., MRI with ultrasound).
• Endovascular iMRI is clinically established for pediatric congenital heart defects and atrial ablation, with potential for wider use.

Conclusions:

• Interventional MRI has proven its value in clinical routine for various indications, particularly where MRI significantly facilitates or improves the intervention.
• Broader clinical adoption is anticipated due to the inherent advantages of MRI over alternative techniques.
• Further development and economic considerations will likely drive expanded use of iMRI in the future.
