Cardiac MR

Cardiac MR

Radiology Regional Center is proud to introduce an exciting new technological advance in cardiac imaging, Cardiac MRI Stress Testing and infarct imaging. For years, we have anticipated a time when Cardiac MRI would play an integral role in the evaluation of coronary heart disease (CHD). We are pleased to inform you that the time for Cardiac MRI is now.

Comprehensive Cardiac Exam

Perhaps the greatest advantage Cardiac MRI offers is the ability to acquire several different data sets within the time frame of a single examination. Stress perfusion, functional and viability (infarct) imaging can all be performed within a one hour exam.

Cardiac MRI Stress Test

Recent advances in hardware and software allow rapid dynamic MR imaging of the heart. By acquiring one image every heartbeat while performing pharmacologic vasodilation (adenosine) enables one to perform MR perfusion imaging of the heart.

Functional Cardiac Imaging

Cardiac MR imaging excels at functional imaging. In fact, Cardiac MR is the gold standard for imaging ventricular function. Cardiac MR can provide much of the information currently acquired by echocardiography. However, unlike echocardiography, the exam is not operator dependent and not limited by body habitus (ie. COPD or elevated body mass index). Valvular stenosis or regurgitation and cardiac shunts are just a few of the pathologies well assessed by Cardiac MR.

Viability (Infarct) Imaging

By administering intravenous contrast and acquiring special imaging sequences, Cardiac MRI can evaluate the myocardium for any evidence acute or chronic myocardial infarction. Because Cardiac MRI has 60 fold greater spatial resolution compared to Cardiac Nuclear SPECT imaging, Cardiac MR can detect subendocardial infarcts that are invisible to Nuclear SPECT imaging.

Heart Disease Facts
  • Heart disease is by far the number one killer of both men and women in the United States.
  • Over one million people in the U.S. will have a heart attack this year.
  • Half of all heart attacks are fatal.
  • Every 60 seconds, an American suffers a fatal heart attack.
  • Two out of every three first-time heart attack victims have no previous warning.
  • Heart disease can be effectively managed through lifestyle modifications, medications or surgery
