PET/CT Scan Treatments at Gulf International Cancer Center
What is a PET/CT Scan?
A PET/CT scan combines two advanced imaging technologies—Positron Emission Tomography (PET) and Computed Tomography (CT)—to provide both functional and anatomical insights into the body. The PET scan detects metabolic activity, revealing how tissues and organs are functioning, while the CT scan produces detailed cross-sectional images of the body's structure.
This powerful combination enables doctors to detect cancer, accurately stage its progression, plan targeted treatments, and monitor response to therapy. By offering a comprehensive view of both tumor activity and location, PET/CT scans are invaluable in delivering precise and personalized cancer care.

PET/CT scans combine two advanced imaging technologies to deliver highly accurate diagnostic insights:
- Radioactive Tracers: A small amount of a disease-specific radioactive tracer is injected into the patient’s body. The tracer travels to the targeted area, highlighting abnormal metabolic activity.
- PET Scan: The PET component detects and maps metabolic activity, identifying areas of abnormal function, such as cancer cells with high glucose uptake.
- CT Scan: The CT component captures detailed structural images of the body, providing precise localization of abnormalities identified by the PET scan.
The synergy of these imaging methods allows for comprehensive diagnosis, accurate cancer staging, and effective treatment monitoring, enhancing patient outcomes.

Advanced Tracers for PET/CT Imaging
18-FDG (Fluorodeoxyglucose)
18-FDG is the most commonly used tracer for PET/CT imaging, particularly in detecting and staging cancers. It measures glucose metabolism, as tumors typically exhibit higher glucose uptake than normal tissues, aiding in accurate diagnosis and monitoring.
PSMA (Prostate-Specific Membrane Antigen)
PSMA is a specialized tracer for prostate cancer imaging. It identifies prostate cancer cells and metastatic sites with precision, making it invaluable for staging and detecting disease spread, even at early stages.
DOTA (DOTA-Peptides)
DOTA-based tracers target somatostatin receptors, making them highly effective in imaging neuroendocrine tumors. They provide clear localization of tumors, guiding treatment decisions with enhanced accuracy.
Choline
Choline tracers are particularly useful for prostate cancer imaging, especially in cases of biochemical recurrence. They track cell membrane synthesis in rapidly dividing cancer cells, enabling precise detection and treatment planning.
DOPA (Dihydroxyphenylalanine)
DOPA tracers are used to image neuroendocrine tumors and certain brain disorders. By detecting specific metabolic activity, they help identify and assess tumors with high precision.
FAPI (Fibroblast Activation Protein Inhibitors)
FAPI is an innovative tracer targeting cancer-associated fibroblasts, which are critical in tumor development. It shows great potential in imaging various cancers, including those that are traditionally hard to detect.
FES (Fluoroestradiol)
FES is specifically designed to image estrogen receptor-positive breast cancer. It helps evaluate treatment options and monitor tumor response, supporting personalized cancer care.
Sodium Fluoride (NaF)
NaF is a highly effective tracer for imaging bone metastases and assessing bone health. It provides detailed, high-resolution images of bone lesions, aiding in diagnosis and treatment planning.
What to Expect During a PET/CT Scan
- Preparation Before the Scan: You may be asked to fast for 4–6 hours before the procedure to ensure accurate results. Avoid strenuous activity 24 hours prior, and inform your healthcare team about any medications or medical conditions, such as diabetes or pregnancy.
- Tracer Injection: A small amount of a specific radioactive tracer, tailored to your medical condition (e.g., 18-FDG or PSMA), is injected into your bloodstream. You’ll rest quietly for about 30–60 minutes while the tracer circulates and accumulates in the target area.
- During the Scan: The scan typically takes 20–45 minutes. You’ll lie still on a cushioned table as it moves through the PET/CT scanner, which captures both functional and structural images of your body.
- After the Scan: You can resume normal activities immediately, as the tracer is safely eliminated from your body naturally. Your doctor may provide additional recommendations based on your results or treatment plan.
