What does persistent diffuse uptake mean on a bone scan?
There is an increased level of metabolic activity of the bone throughout the body.
What does physiologic uptake mean in a bone scan?
There is metabolic activity in the bone at levels expected through normal (physiologic) processes.
What does physiological increased uptake mean in a bone scan?
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.
Can bone injury cause uptake in bone scan?
Yes, bone injuries can lead to increased uptake in a bone scan. This occurs because bone scans detect areas of increased bone metabolism or activity, which often happens in response to injury, inflammation, or infection. Conditions such as fractures, stress injuries, or even arthritis can result in heightened radiotracer accumulation, indicating the presence of healing or pathological processes in the bone.

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.
What is inhomogeneous uptake in the osseous structure?
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.

What do black spots indicate on bone scan?
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.
What does uptake mean in a bone 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.
What is mild uptake at the tip of femoral component of the prosthesis?
Mild uptake at the tip of the femoral component of a prosthesis, often observed on imaging studies like a PET scan or bone scan, typically indicates low-level metabolic activity or bone remodeling in that area. This can be a normal response to the presence of an implant, suggesting that the bone is adapting to the prosthesis. However, it could also indicate potential issues such as infection, loosening, or stress reactions. Clinical correlation and further evaluation may be necessary to determine the significance of the uptake.
What does asymmetric increased uptake mean in a bone scan?
Asymmetric increased uptake in a bone scan refers to a situation where one side of the skeleton shows greater radioactive tracer absorption compared to the other side. This finding can indicate various conditions, such as inflammation, infection, trauma, or neoplastic activity in the bone. The asymmetry suggests that there may be an underlying pathology affecting the more active area, warranting further investigation to determine the cause.
What is foci in a bone scan?
In a bone scan, "foci" refers to specific areas of increased uptake of the radioactive tracer used during the imaging process. These areas may indicate abnormal bone metabolism, which can be associated with various conditions such as fractures, infections, tumors, or arthritis. The presence and pattern of these foci help physicians assess bone health and diagnose underlying issues.
