PET-CT Scan in Delhi

How is PET-CT different from a regular CT scan?

A regular CT only shows anatomy and structure, while PET-CT overlays metabolic activity onto that anatomy, helping distinguish active cancer cells from scar tissue or benign changes.

Do I need to fast before a PET-CT scan?

Yes, fasting for about 4-6 hours and avoiding sugary foods or strenuous exercise the day before is usually required for accurate tracer uptake.

Is the radiation exposure from a PET-CT scan a concern?

The combined radiation dose is higher than a plain X-ray but considered acceptable for the diagnostic benefit it provides, and your doctor will only recommend it when clinically necessary.

How soon will I get my PET-CT report?

Reports are typically ready within 24-48 hours and should be reviewed with your oncologist to interpret the findings in the context of your treatment plan.

Can diabetics undergo a PET-CT scan?

Yes, but blood sugar levels need to be well controlled before the scan since high glucose can interfere with tracer uptake and image accuracy; inform the center about your diabetes in advance.
