Increased uptake in medical terms refers to an increase in the absorption or utilization of a substance by the body. This can refer to the uptake of nutrients, medications, or other substances that are essential for health and functioning.
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.
There is a particular area of bone that is much more metabolically active than the bone in the rest of the body.
The focal increased tracer uptake in multiple bones suggests the possibility of metastatic bone disease, where cancer cells have spread to the bones from a primary tumor. Further evaluation and imaging studies are needed to determine the primary source of the cancer. Treatment would involve addressing the primary tumor, as well as managing the metastatic bone disease.
There is an increased level of metabolic activity of the bone throughout the body.
Inhomogeneous uptake in the osseous structure refers to uneven distribution of a radioactive tracer in the bones during a nuclear medicine bone scan. This may indicate areas of abnormal bone metabolism, such as fractures, infections, tumors, or bone remodeling. Further evaluation is typically needed to determine the underlying cause of the inhomogeneous uptake.
A radioactive tracer called technetium-99m is commonly used in bone scans. This tracer is injected into the bloodstream and accumulates in areas of the bones where there is increased activity, such as in cases of fractures, infections, or tumors.
Black spots on a bone scan may indicate areas of increased bone activity or hot spots, which can be caused by conditions such as fractures, infection, inflammation, or bone tumors. These areas typically show up as dark areas on the scan due to higher uptake of the radioactive tracer used in the scan.

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 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.
