Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Area of Science:

  • Cardiovascular Imaging
  • Preclinical Research
  • Magnetic Resonance Imaging

Background:

  • Assessing myocardial perfusion is crucial for understanding ischemic heart disease.
  • Mouse models are vital for preclinical cardiovascular research.
  • Advanced imaging techniques are needed for high-resolution cardiac assessment in mice.

Purpose of the Study:

  • To develop and validate a first-pass myocardial perfusion sequence for mouse cardiac MRI.
  • To assess the reproducibility and accuracy of the technique in detecting perfusion deficits.
  • To establish a tool for preclinical studies of ischemic heart disease.

Main Methods:

  • Utilized a segmented, ECG-triggered acquisition with parallel imaging acceleration.
  • Captured the first pass of a Gadolinium-DTPA (Gd-DTPA) contrast agent bolus.
  • Achieved a temporal resolution of 300-400 milliseconds.
  • Applied the method in healthy mice and mice with induced coronary artery occlusion.

Main Results:

  • Demonstrated excellent reproducibility of semiquantitative perfusion values in healthy mouse myocardium.
  • Identified significantly decreased myocardial perfusion values in infarct regions (0.05 ± 0.02) compared to remote myocardium (0.20 ± 0.04).
  • Showed strong correlation between areas of decreased perfusion and infarct areas on delayed-enhancement scans.

Conclusions:

  • The developed first-pass myocardial perfusion MRI sequence is a valuable addition to the preclinical research toolbox.
  • This technique enables accurate, reproducible assessment of myocardial perfusion in mouse models of ischemic heart disease.
  • The findings support the use of this method for evaluating therapeutic interventions in preclinical settings.
