Perfusion Imaging: Assessing the extent of coronary heart disease before and after treatment

Myocardial perfusion, or blood flow to the heart can be quantitatively determined with PET, allowing changes in blood flow to be measured before and after treatment of coronary heart disease. The highly sensitive PET scan can re-evaluate blood flow after bypass surgery or angioplasty, can measure progression of coronary heart disease over time, and can measure the improvement in coronary heart perfusion with therapies, such as lipid lowering treatment.
