As the name implies, PET/CT combines two state-of-the-art technologies in one. PET (Positron Emission Tomography) highlights the abnormal metabolic function of cells. CT (Computed Tomography) then can depict the exact location of the cells with precision and clarity.  Together, these images create a 3-D picture that enables doctors to make better decisions for earlier cancer treatment. PET/CT is also useful for following response to therapy and allows early detection of cancer recurrence, which can increase the likelihood of treatment success.  PET/CT's critical data are used today in treating various forms of cancer, cardiovascular diseases, and even Alzheimer’s disease. 

To prepare for a PET/CT: 

  • Wear warm, comfortable clothing. 

  • Patient should arrive 30 minutes early to register and have blood sugar checked.

  • Patient’s entire visit to the hospital will last about two hours. 

  • Eat a low carbohydrate/high protein diet (e.g. meat, cheese, beans, vegetables) the evening before your procedure.

  • Refrain from eating foods high in sugar or desserts. 

  • Do not eat or drink (except plain water) four hours prior to your procedure.

  • Take medications with water or saltine crackers if food is required. 

  • Do not exercise the morning of your procedure. 

  • If you take insulin, it must be taken at least four hours before your procedure. 

  • You should bring medications for pain, anxiety or claustrophobia, if you need them. If you take medications for anxiety or claustrophobia, please make sure you have someone with you to drive you home after your appointment. 

  • Materials for this procedure are ordered in advance and are time-sensitive. If you need to cancel or re-schedule, you must call 606-833-3926 at least 48 hours prior to your appointment time. 

  • Bring recent CT scan results from facilities other than Our Lady of Bellefonte Hospital.
