Measuring metabolic and perfusion rate within the heart, cardiac PET scans can pinpoint areas of blockage or impairment and evaluate myocardial viability.
This information is particularly important for patients with a history of myocardial infarctions and those being considered for a revascularization procedure. PET can help determine if bypass surgery or a transplant would be the appropriate treatment.
PET cardiac can aid in the treatment of your patients with the following indications:
- Myocardial viability (F-18-FDG)
Particularly helpful after a nonreversible defect is seen on thallium-201 SPECT (some of these patients have extensive viability by PET)
- Myocardial perfusion (rubidium-82)
Particularly helpful in the following situations:
- After equivocal thalllium or sestamibi (Cardiolite) SPECT study
- Discordant clinical, ECG, and myocardial perfusion SPECT results
- Large breasted women or very obese patients
