Brief Summary:

The investigator aims to determine the feasibility of understanding the process of active versus chronic calcification using Na-F PET scan and contrast CT scan of the heart.

The patient cohort will consist of patients diagnosed to have either acute coronary syndrome (ACS) (comprising of either unstable angina pectoris or acute myocardial infarction) or suspected coronary artery disease (CAD). The PET images will be compared to images obtained from standard contrast CT of the coronaries. This study will provide additional insights about active versus non-active calcification amongst patients with ACS or suspected CAD.

Detailed Description:

Contemporary techniques used to visualize coronary artery calcification include standard non-contrast computed tomography (CT) of the coronaries measuring amount of calcium deposition in the coronaries, contrast CT and more recently, using sodium-fluoride (Na-F) positron emission tomography (PET) to image coronary and valvular calcification. Na-F has been shown to accumulate in areas of active calcification where contrast CT of the heart has been shown to accumulate in areas of chronic calcification. The investigator aims to determine the feasibility of understanding the process of active versus chronic calcification using Na-F PET scan and contrast CT scan of the heart.

Primary Outcome Measures :
  1. Coronary artery calcification will be determined by Tc-99m MDP SPECT-CT and Na-F PET-CT [ Time Frame: 12 months ]
    Na-F has been shown to accumulate in areas of active calcification where contrast CT of the heart has been shown to accumulate in areas of chronic calcification. We aim to determine the feasibility of understanding the process of active versus chronic calcification using Na-F PET scan and contrast CT scan of the heart.
