What is physiologic uptake on a PET scan?
The normal physiologic accumulation of 18F FDG in the body is based on glucose metabolism, which can be variable. Physiologic uptake is normally seen in the brain, heart, liver, spleen, gastrointestinal tract, urinary collecting system (including the bladder), and bone marrow (Fig 1).
What is likely physiologic?
Physiologic: Something that is normal, that is due neither to anything pathologic nor significant in terms of causing illness. For example, physiologic jaundice is jaundice that is within normal limits.
What does physiologic mean in medical terms?
What does physiologic excreted activity mean?
The physiological process by which an organism disposes of its nitrogenous by-products is called excretion. The mechanisms for that process constitute the excretory systems, particularly such organs of vertebrate animals as elaborate and complicated as the kidney and its associated urinary ducts.
What is physiological FDG?
INTRODUCTION. F-18 fluorodeoxyglucose (FDG) is the radiotracer most commonly used for PET imaging. The molecule is easiest to understand by interpreting it backwards, starting with the molecule of glucose. The deoxy part implies cleavage of a hydroxyl group from the glucose.
Which is the best definition of physiological activity?
Physiological activity refers to the normal function of an organism. It may refer to specific organs or the organism as a whole.
How does age affect FDG uptake in the liver?
Impact of age on FDG uptake in the liver on PET scan Age has a significant and positive impact on both maximum and mean standard uptake values of the liver on FDG PET imaging. High physiological background FDG uptake will reduce diagnostic sensitivity and accuracy for malignancy detection in the liver.
Where does physiologic uptake take place in the body?
The normal physiologic accumulation of 18F FDG in the body is based on glucose metabolism, which can be variable. Physiologic uptake is normally seen in the brain, heart, liver, spleen, gastrointestinal tract, urinary collecting system (including the bladder), and bone marrow (Fig 1). Explore more on it.
