Answered by Master, Doctor Pham Quoc Thanh - Department of Diagnostic Imaging, Vinmec Hai Phong International General Hospital.
Hello,
With the question “Can you eat and drink before PET/CT scan? ", the doctor would like to answer as follows:
PET/CT scan is a diagnostic imaging method of computed tomography combined with oral radiotherapy (PET) to evaluate and detect tumors in the colon. body, especially evaluate the stage of cancer and re-evaluate after treatment when cancer is confirmed.
This diagnostic method is expensive and you may get 2 times of radiation (computed tomography and oral radiation). A PET/CT scan can screen you for lung cancer, but it should be replaced with a less expensive, less radioactive method like computed tomography.
Before the PET/CT scan, you need to fast for at least 6 hours before the scan, and don't drink energy drinks, sugar and caffeine. You should also drink plenty of water.
If you still have questions about whether you can eat or drink before a PET/CT scan, you can go to a hospital under Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
