Overview

Supports CMR for precise serial ventricular monitoring in trials; leaves open broader clinical adoption and cost-effectiveness.

Key Points

  • To review the technical modalities and primary clinical applications of cardiovascular magnetic resonance (CMR) imaging across acquired and congenital heart conditions.
  • Synthesized evidence on cardiovascular MRI techniques for anatomical, functional, and tissue-level cardiac characterization.
  • Evaluated clinical utility of delayed contrast enhancement and first-pass myocardial perfusion relative to conventional diagnostic methods.
  • Cardiovascular MRI provides the highest precision and reproducibility for measuring ventricular volumes, ejection function, and myocardial mass.
  • Delayed contrast enhancement reliably identifies tissue scarring and fibrosis in ischemic cardiomyopathy, nonischemic cardiomyopathy, myocarditis, and cardiac sarcoidosis.
  • First-pass contrast myocardial perfusion offers a non-ionizing alternative to radionuclide techniques for diagnosing coronary atherosclerotic disease.

Structured PICO

I
Intervention
Cardiovascular magnetic resonance imaging (MRI)

Cardiovascular MRI is a versatile and highly accurate imaging modality with broad clinical applications in ischemic and nonischemic heart disease, congenital anomalies, and vascular conditions.

Limitations

  • Contraindicated in patients with pacemakers, implanted cardioverter-defibrillators, neurostimulators, cochlear implants, and certain vascular clips.
  • Claustrophobia during MRI is reported in approximately 5% of patients.
  • Small vessel size and cardiac motion limit the clinical value of MRI for suspected coronary atherosclerotic disease.
  • High initial cost for comprehensive cardiovascular MRI testing.
