PET scan in Israel uses a radiotracer—18F-FDG (fluorodeoxyglucose)—to highlight areas of abnormal metabolic activity. This enables doctors to detect tumors and metastases, even at very early stages. It is a key method in PET imaging for cancer and increasingly applied in complex diagnostic cases abroad as well, including in PET-CT abroad clinics.
PET-CT Scan with 18F-FDG
What is a PET-CT Scan with 18F-FDG?
Preparation for the Procedure
For optimal results, certain preparation guidelines must be followed:
- Patients undergoing chemotherapy should wait at least two weeks before scheduling a PET-CT with 18F-FDG.
- After radiation therapy, it is advised to wait at least six weeks.
- If you are receiving medications that increase white blood cells, pause for 14 days before the scan.
- In cases of biological therapy or steroid treatment, consult the Nuclear Medicine Center regarding optimal timing.
- Hormonal and bisphosphonate therapy can usually continue as scheduled.
Additional instructions:
- Avoid physical exertion for 48 hours before the scan.
- Do not eat or drink (except water) for 4–6 hours prior to the procedure.
- Bring recent bloodwork showing creatinine levels (within the past 3 months).
- If you have prior imaging results (CT, MRI, PET), bring them on a CD, along with biopsy reports.
- Wear warm clothing and avoid jewelry on the day of the scan.
Special Instructions for Diabetic Patients
Diabetic patients should ensure blood sugar is below 150 mg/dL to maximize scan quality. In such cases, it is recommended to schedule the scan in the afternoon. Medication or insulin can be taken in the morning, followed by a light breakfast, after which fasting should continue (only water allowed).
If your scan includes contrast material, and you are taking oral hypoglycemic agents, suspend the medication 48 hours before and after the procedure in consultation with your referring physician.
How the PET-CT Scan Is Performed
The visit to the PET-CT center in Israel usually takes around four hours and includes:
- Registration and a brief consultation with the physician and nurse.
- Blood glucose check, IV catheter placement, and administration of 1.5 liters of contrast fluid to enhance intestinal visualization.
- Intravenous injection of 18F-FDG (fluorodeoxyglucose). If there are no contraindications, IV contrast may also be used.
- One-hour resting period in an isolation room.
- The FDG PET scan itself, lasting approximately 20 minutes.
Are There Any Side Effects?
There are no known side effects associated with PET-CT without waiting time or delays. The procedure is safe and non-invasive.
