Real-time magnetic resonance imaging offers detailed cardiovascular insights, guiding interventions in animal models. This advanced imaging may surpass traditional methods for various heart and vascular procedures.

Area of Science:

  • Cardiovascular imaging and interventions
  • Medical physics and engineering

Background:

  • Magnetic resonance imaging (MRI) offers superior soft tissue contrast for cardiovascular assessment.
  • Current imaging modalities have limitations in guiding complex cardiovascular interventions.

Purpose of the Study:

  • To explore the potential of real-time magnetic resonance imaging (rt-MRI) for guiding transcatheter cardiovascular interventions.
  • To detail technical considerations, preclinical data, and early clinical findings of rt-MRI in this field.

Main Methods:

  • Review of technical advancements enabling real-time MRI acquisition and processing.
  • Analysis of preclinical studies in large animal models.
  • Summary of early clinical experiences with rt-MRI guided interventions.

Main Results:

  • Real-time MRI provides high-resolution structural and functional cardiovascular information.
  • rt-MRI successfully guided complex interventions in preclinical settings.
  • Emerging clinical data suggest potential advantages over conventional imaging.

Conclusions:

  • Real-time MRI is a promising technology for guiding a range of cardiovascular interventions.
  • Further development and clinical validation are warranted to establish rt-MRI as a standard of care.
