What is meant by scintigraphy?

(sin-TIH-gruh-fee) A procedure that produces pictures (scans) of structures inside the body, including areas where there are cancer cells. Scintigraphy is used to diagnose, stage, and monitor disease.

Is nuclear medicine the same as chemotherapy?

Nuclear medicine therapy is an approach to treating cancer that might be used with or after other treatment options, such as chemotherapy and surgery. It won’t usually lead to a cure unless combined with other therapies.

Which is the most common indication for a nuclear bone scan?

Listed below are some common reasons to refer for a bone scan: occult fractures, stress fracture, shin splints; osteomyelitis, cellulitis or assessing response to treatment (e.g. antibiotics);2017-07-26

What is a gamma scan used for?

It can be used to diagnose various conditions and examine the structure and function of many different parts of the body, including the heart, brain, lungs, and kidneys. It may be used to assess if the patient’s organs or tissues are healthy enough to undergo a certain operation or to assess if they need one.

Can a bone scan tell the difference between cancer and arthritis?

Many changes that show up on a bone scan are not cancer. With arthritis, the radioactive material tends to show up on the bone surfaces of joints, not inside the bone. But it can be hard to tell the difference between arthritis and cancer — especially in the spine.2022-02-02

What is scintigraphy in nuclear medicine?

A bone scan (skeletal scintigraphy) is a special type of nuclear medicine procedure that uses small amounts of radioactive material to diagnose and assess the severity of a variety of bone diseases and conditions, including fractures, infection, and cancer.

Is scintigraphy the same as nuclear medicine?

A Scintigraphy or Radionuclide Scan is commonly called nuclear medicine. It produces pictures of structures inside the body, and helps with diagnosis for a wide range of conditions. Nuclear medicine uses a tracer dye, which is mildly radioactive but is considered very safe.

What counts as nuclear medicine?

Nuclear medicine is a specialized area of radiology that uses very small amounts of radioactive materials, or radiopharmaceuticals, to examine organ function and structure.

What are examples of nuclear medicine?

Nuclear medicine procedures are used in diagnosing and treating certain illnesses. These procedures use radioactive materials called radiopharmaceuticals. Examples of diseases treated with nuclear medicine procedures are hyperthyroidism, thyroid cancer, lymphomas, and bone pain from some types of cancer.

Does uptake on a bone scan mean cancer?

Defects in uptake in the bone may be seen with a number of malignancies, typically lung cancer and breast cancer and occasionally in myeloma. Also through a number of benign diseases such as haemangioma, bone infarct associated with haemoglobinopathies and fat infiltration as in Gaucher’s disease.

What can a gamma camera diagnose?

The most widespread of nuclear medical diagnostics. Gamma cameras or scintillation cameras are pieces of apparatus which allow radiologists to carry out ‘scintigraphy scans’, tests which provide detailed diagnoses about the functioning of the thyroid, the heart, the lungs and many other parts of the body.

What does a gamma scan show?

Certain tumours and areas of your body absorb specific chemicals. These chemicals are made mildly radioactive and then put into your bloodstream. Because the tumours and/or the area of your body absorb the substance which is giving off gamma rays, they show up on the scan.

What is nuclear medicine also known as?

Nuclear medicine radiologists, also called nuclear radiologists, are physicians who use radioactive materials, called radiopharmaceuticals, to diagnose and treat disease. They employ such techniques as scintigraphy, which uses radiopharmaceuticals to produce images of the body’s organs or to visualize certain diseases.

Is scintigraphy same as PET scan?

18F-FDG-PET/CT and bone scintigraphy exploit different mechanisms to detect tumor involvement in bone skeleton. Bone scintigraphy relies on an osteoblastic bone response to tumor, whereas 18F-FDG-PET/CT measures glucose uptake into the tumor itself.2016-05-27

Is nuclear medicine harmful?

Yes, nuclear medicine procedures are very safe. We carefully select the radiotracer and radiation dose to ensure the minimum radiation exposure and maximum accuracy. You are exposed to about as much radiation in a nuclear medicine test as with a diagnostic X-ray.

What is nuclear medicine treatment?

Nuclear medicine uses radioactive material inside the body to see how organs or tissue are functioning (for diagnosis) or to target and destroy damaged or diseased organs or tissue (for treatment).

What causes increased uptake on bone scan?

Thus, increased radiotracer uptake occurs with multiple pathologic processes such as fractures, infection, malignant disease and less commonly encountered osseous diseases like Paget disease, fibrous dysplasia, osteoid osteoma, and complex regional pain syndrome.2021-08-11
