Myocardial Viability

Myocardial viability is the ability of heart muscle to contract and have adequate muscle tone around the left ventricle to pump blood throughout the body.

If blood flow to the heart muscle has been decreased or absent due to coronary artery disease, the heart tissue may appear to have irreversible myocardial damage. In some cases, if the blood flow is restored to the heart through angioplasty or coronary bypass surgery, the heart tissue will recover.


Information from the PET/CT scan allows physicians to detect damaged heart tissue.


The results of the PET/CT scan will help the physician determine the best course of treatment.


Myocardial viability imaging can be used to assess whether the treatment was successful.

PET/CT Utilization and Case Studies

PET/CT is a noninvasive test that physicians utilize to stage the entire body for the presence or absence of active tumor, localize the tumor, assess the tumor response to treatment and detect recurrence in treated lesions.
