What does FDG in medical terms mean?

Those abbreviations stand for: fluorodeoxyglucose (FDG)-positron emission tomography (PET). The role of this procedure is to detect metabolically active malignant lesions including lung cancer, colorectal cancer, lymphoma, melanoma, breast cancer, ovarian cancer, brain cancer and multiple myeloma.

What does FDG mean on a scan?

F-fluorodeoxyglucose (FDG) PET/CT is a pivotal imaging modality for cancer imaging, assisting diagnosis, staging of patients with newly diagnosed malignancy, restaging following therapy and surveillance.

What does FDG positive mean?

FDG-positive lesions often mean cancer, but not always. A variety of lesions have increased FDG radiotracer including infection, inflammation, autoimmune processes, sarcoidosis, and benign tumors. If such conditions are not identified accurately and in a timely manner, misdiagnosis can lead to inadequate therapies.

What is the FDG used in PET scan?

The PET scanner takes a picture of where glucose is being used in the brain. PET scanning utilizes a radioisotope tracer that is an analog to glucose, called fluorodeoxyglucose (FDG). FDG accumulates within malignant cells because of their high rate of glucose metabolism.

What is whole body FDG?

A PET-CT is a Nuclear Medicine imaging test used commonly for diagnosis in oncology (cancers), heart diseases, neurological conditions, infections and PUO (Pyrexia of Unknown Origin).

What is difference between FDG PET and PET-CT?

However, in the majority of cases, FDG PET is a sensitive imaging modality for the detection, staging, re-staging as well as for assessment of therapy response in oncology [6, 17–25]. In contrast to PET, computed tomography (CT) uses an x-ray beam to generate tomographic images.

Is PET scan the same as full body scan?

Whole-body scans use a lot of radiation. The scans use two kinds of technology: CT (computed tomography) scan: Takes many X-ray pictures of the body. PET (positron emission tomography) scan: Radioactive material is injected into the body and collects in areas with cancer.
