Viability assessment
Checking whether heart muscle with reduced function is still alive and may benefit from treatment.
Cardiac PET-CT
Cardiac PET-CT in Gurugram.
PET-CT to assess heart muscle viability and inflammation.
FDG PET-CT studies of the heart to assess whether damaged heart muscle is still viable, and to look for inflammation in conditions such as cardiac sarcoidosis.

About Cardiac PET-CT
Understanding heart musclebeyond its structure.
Cardiac FDG PET-CT shows how heart muscle uses glucose. Heart muscle that is still metabolically active looks different from scarred tissue, and areas of active inflammation can also take up FDG. Results are interpreted together with your echocardiogram, MRI, angiography and clinical findings.
Myocardial viability
FDG PET-CT helps show whether heart muscle with reduced function is still viable, which can inform decisions about restoring blood flow.
Inflammation imaging
FDG uptake can help identify active inflammation, as in suspected cardiac sarcoidosis, and may be used to review response to treatment.
Your cardiologist will advise whether this study is appropriate for you.

When It May Help
Supporting decisions about your heart.
Your cardiologist recommends imaging based on your clinical needs.
Cardiac sarcoidosis
Looking for active inflammation of the heart muscle when sarcoidosis is suspected or known.
Reviewing treatment response
Where inflammation is being treated, imaging may help your team review how it is responding.
Heart team decisions
Findings are one part of the information your cardiology team uses to plan your care.
Your Visit, Step by Step

The exact process depends on your scan and clinical needs.
Before Your Visit
Preparing for your visit.Simple steps.
What to discuss with the team
Your referral & cardiac reports
Bring the referral and earlier echocardiogram, MRI, angiography or ECG reports where available.
Diet & fasting
Cardiac FDG scans often need a specific diet or fasting beforehand, and the instructions differ for viability and inflammation studies. The team will give you exact instructions.
Diabetes & medicines
Blood sugar control matters for these scans. Tell the team about diabetes, insulin and all heart medicines, and do not change any without advice.
Pregnancy, breastfeeding & allergies
Let the team know before your appointment.
Guidance tailored to you
Preparation varies by study. Contact the team if you are unsure about any instruction.

FAQs
Common questionsabout cardiac PET-CT.
Answers to questions patients often ask before a cardiac scan.
Still have questions?Speak to our team for guidance before your visit.
For some cardiac FDG scans, diet or fasting is used to control how normal heart muscle takes up FDG so the images can be read correctly. The plan depends on the reason for your scan and the team will explain it.
No. A viability study asks whether heart muscle is still alive and able to benefit from restored blood flow, while stress tests look at blood flow under stress. Your cardiologist decides which is needed.
It can, because FDG behaves like sugar in the body. Tell the team about diabetes and your medicines so they can advise you on preparation.
The time varies by study. The team will tell you what to expect when arranging your appointment.
Nuclear medicine studies use a small amount of radioactivity and the team follows radiation safety practices. Tell the team if you are pregnant or breastfeeding, or think you might be.
Your referring doctor will usually discuss the findings with you. Contact the team about when your report will be available.
