FDG PET/CT Scan for Cancer Imaging
Advanced Cancer Detection and Monitoring
At Capitol Imaging Services, we offer advanced FDG PET/CT imaging to help physicians detect, stage, and monitor a wide range of cancers with exceptional accuracy.
FDG (fluorodeoxyglucose) is a specialized radiotracer used during a PET/CT scan. Because cancer cells are more metabolically active than normal cells, they absorb more FDG—allowing physicians to identify abnormal activity throughout the body.
By combining PET (which shows how cells function) with CT (which shows detailed anatomy), FDG PET/CT provides a powerful, comprehensive view of cancer.
What Is FDG PET/CT Imaging?
FDG PET/CT is a type of nuclear medicine imaging that evaluates how tissues and organs are functioning at the cellular level.
- PET imaging detects metabolic activity in cells
- CT imaging pinpoints the exact location of abnormalities
- Together, they allow physicians to identify cancer earlier and with greater precision
This combination enables detection of disease before structural changes are visible on traditional imaging, supporting earlier diagnosis and more effective treatment planning.
When Is FDG PET/CT Used?
Physicians commonly use FDG PET/CT to:
- Detect cancer and differentiate between benign and malignant disease
- Determine if cancer has spread (staging)
- Evaluate how well treatment is working
- Identify recurrence after treatment
Cancers Commonly Evaluated with FDG PET/CT
Thoracic & Pulmonary Cancers
These cancers affect the lungs and chest and are often associated with abnormal growths or nodules that may be benign or malignant.
- Pulmonary nodules / solitary pulmonary nodules
- Non-small cell lung cancer
- Small cell lung cancer
This imaging helps distinguish between benign and malignant nodules, accurately stage lung cancer, and evaluate how well treatment is working.
Gastrointestinal Cancers
These cancers involve the digestive system and may develop in the colon, esophagus, or pancreas, often progressing without early symptoms.
- Colorectal cancer
- Esophageal cancer
- Pancreatic cancer
PET/CT imaging is used to detect the spread of disease, guide treatment planning, and monitor response to therapy.
Gynecologic & Genitourinary Cancers
These cancers affect reproductive and urinary organs and may require imaging to evaluate both local disease and potential spread.
- Ovarian cancer
- Endometrial Cancer
- Cervical cancer
- Testicular cancer
Advanced imaging allows physicians to identify metastatic disease, assess recurrence, and support treatment decisions.
Head, Neck & Endocrine Cancers
These cancers occur in the throat, mouth, sinuses, and hormone-producing glands such as the thyroid.
- Head and neck cancer
- Thyroid cancer
This technology helps locate primary tumors, evaluate lymph node involvement, and detect recurrence.
Hematologic & Systemic Cancers
These cancers affect the blood, lymphatic system, or bone marrow and often involve widespread disease throughout the body.
- Hodgkin lymphoma
- Non-Hodgkin lymphoma
- Multiple myeloma
PET/CT imaging is essential for staging, assessing treatment response, and detecting residual or recurrent disease.
Other Cancers
These cancers can develop in various tissues throughout the body and may require comprehensive imaging to fully evaluate.
- Breast cancer
- Melanoma
- Brain cancer
- Soft tissue sarcoma
- Unknown primary
These scans help evaluate the extent of disease, detect metastases, and monitor treatment effectiveness.
FDG PET/CT helps physicians evaluate both primary tumors and metastatic disease, providing a complete picture of cancer throughout the body.
What to Expect During Your Exam
FDG PET/CT Scan for cancer imaging is a noninvasive and safe medical study.
- A small amount of FDG tracer is injected into a vein
- You will rest quietly while the tracer circulates (typically 60–90 minutes)
- The scan itself usually takes about 15 - 30 minutes
- You will lie comfortably on a table while images are acquired
These studies are generally painless and provide critical information for diagnosis and treatment planning.
