Fluorodeoxyglucose
Full Form of FDG
What is FDG?
Fluorodeoxyglucose (FDG) is a radiolabeled glucose analog used extensively in positron emission tomography (PET) imaging. In the Indian healthcare system, FDG-PET scans are a cornerstone for oncology, neurology, and cardiology diagnostics. FDG is administered intravenously and accumulates in cells with high glucose metabolism—such as cancer cells, inflamed tissues, and active brain regions. The emitted positrons are detected by PET scanners to create detailed metabolic maps. In India, FDG is produced in cyclotron facilities under strict regulatory guidelines from the Atomic Energy Regulatory Board (AERB). It is used in major hospitals and diagnostic centers across cities like Mumbai, Delhi, and Bangalore for staging cancers, monitoring treatment response, and detecting recurrences. For medical students and radiology residents, understanding FDG kinetics and standardized uptake values (SUV) is important for exams like NEET PG and AIIMS. The tracer is generally safe with low radiation exposure, though pregnancy and uncontrolled diabetes are relative contraindications. FDG-PET has revolutionized non-invasive disease assessment, making it a vital tool in precision medicine.
