MRI

Powerful magnets and fast electronics have made it possible to use MRI to image the moving heart. The use of Gadolinium as a contrast agent permits angiography of medium to large arteries without the risk of radiation or iodine containing dyes. CARI is proud to be the only Rhode Island facility that has a cardiac capable MRI scanner and a cardiologist credentialed in interpreting the studies.

• Cardiac MR

  MRI of the heart allows for exquisite imaging of the heart and its surrounding tissues – with more functional resolution than with Echo. Structural and functional assessment of valve function (stenosis and regurgitation) and ventricular function mimic data obtained with echocardiography. Dobutamine stress is used to assess ischemia. MRI is uniquein its ability to distinguish viable myocardium from scar, facilitating decisions regarding the value of revascularization.
  
  

• Cardiac MR Angiography (MRA)

  MRI allows for arterial angiography of most arteries. The small size and constant movement of the coronaries prevents adequate coronary arteriography in most patients (see CT). The choice between MR angiography and CT angiography is made on a case-by-case basis. CARI offers both tests in the same office facility.
