Area of Science:

  • Cardiovascular Imaging
  • Medical Physics
  • Diagnostic Radiology

Background:

  • Gated magnetic resonance imaging (MRI) provides high-resolution cardiac visualization.
  • Assessing cardiac physiology requires capturing both systolic and diastolic phases.

Purpose of the Study:

  • To evaluate the accuracy of MRI in determining left ventricular ejection fraction.
  • To compare MRI findings with established angiocardiography and radionuclide ventriculography.

Main Methods:

  • Left ventricular ejection fraction was calculated using the area-length formula from oblique long axis MRI views in 50 patients.
  • Electronic gradient angulation was employed for acquiring angulated views.
  • Comparison data included monoplane angiocardiography and radionuclide ventriculography.

Main Results:

  • MRI ejection fraction showed a strong correlation with angiocardiography (r=0.90).
  • MRI also demonstrated acceptable correlation with radionuclide ventriculography (r=0.79).
  • MRI provides data on regional wall motion in addition to global function.

Conclusions:

  • Gated cardiac MRI is a reliable method for assessing left ventricular ejection fraction.
  • Emerging MRI techniques with faster imaging show promise for detailed cardiac cycle analysis.
  • MRI offers combined anatomical and functional information for cardiovascular assessment.
