There is an increased level of metabolic activity of the bone throughout the body.
There is metabolic activity in the bone at levels expected through normal (physiologic) processes.
Physiological increased uptake in a bone scan refers to the normal uptake of the radioactive tracer by certain structures in the body, such as the bones, liver, and spleen. This uptake is considered to be within the expected range and does not necessarily indicate any abnormality or disease. It is important for the interpreting physician to distinguish between physiological uptake and abnormal uptake associated with a pathology.
Diffuse osteopenia refers to a decrease in bone density throughout the skeleton. This condition can predispose individuals to fractures and may be caused by various factors such as aging, hormonal changes, nutritional deficiencies, or certain medical conditions. Treatment may involve lifestyle modifications, medication, and monitoring bone health.
The term uptake, when used in connection with the imaging method called a bone scan, refers to the amount of radioactive material that is taken in (taken up - uptake) by the bones to facilitate the imaging. To image bones this way, a radioactive chemical that "looks" like stuff that bones want to facilitate their health is injected into a patient. The bones see this material and start to collect it, and they end up gathering about half of it up (ball park figure). This causes the bones to "glow" with the emissions of the decaying radioactive material used in the procedure. An imaging system with a camera sensitive to the gamma rays is used to "look" at the bones and an image results. The uptake of the tracer will be determined by how fast the metabolism of the bone is working. Faster metabolism will mean more uptake. Cancer, infection and a few other things cause a lot of uptake, and that is what makes them visible. They stand out as "hot spots" on the image. The body metabolizes and dumps the radioactive material through the kidneys and urinary tract. You don't get any more radiation than a conventional X-ray gives you - probably quite a bit less. The tracer, commonly 99mTc-Medronate (MDP), is a phosphate-based compound with technetium hooked in so the material will "glow" in the gamma ray spectrum and can be seen with equipment set up to look for electromagnetic radiation in those energy ranges. The nuclear medicine technologist can probably answer more questions for you, as can your physician.
Increased uptake seen in a Bone scan can mean many things:To name a few of the most popular causes:InfectionTraumaDegenerative ChangesCancerIncreased uptake is also known as a Hot Spot - This helps Doctors locate problematic areas for further investigation and specific imaging that best shows anatomical structures of the HOT SPOT. Correlation is made with imaging along with blood work, symptoms and history to reach a diagnosis or good reason that warrants further investigation for more sinister causes.Hopefully this helps!Sean DIncreased uptake seen in a Bone scan can mean many things:To name a few of the most popular causes:InfectionTraumaDegenerative ChangesCancerIncreased uptake is also known as a Hot Spot - This helps Doctors locate problematic areas for further investigation and specific imaging that best shows anatomical structures of the HOT SPOT.

Increased uptake in a sacroiliac joint on imaging studies like bone scans or MRI may suggest inflammation or active disease in the joint. This could be related to conditions such as sacroiliitis or arthritis affecting the joint. Further evaluation and follow-up may be needed to determine the underlying cause.

Standardized Uptake Value (radionucleide uptake used in reading a PET scan)
'Diffuse' means "spread out," so diffuse abdominal pain is pain that encompasses the entire abdomen and is not limited to one certain part of the abdomen.
