Quick Answer: How Does Nuclear Scintigraphy Work?

What does a spot on a bone scan mean?

The areas where the radionuclide collects are called “hot spots,” and may indicate the presence of conditions such as arthritis , malignant (cancerous) bone tumors , metastatic bone cancer (cancer which has spread from another site, such as the lungs), bone infections , bone trauma not seen on ordinary X-rays, and ….

How long does nuclear medicine stay in your body?

Are bone scans accurate?

Ohta and colleagues compared PET and bone scan in evaluation of skeletal metastases in 51 patients with breast cancer and found that the sensitivity, specificity and accuracy of the bone scan were 77.7%, 80.9% and 80.3%, respectively.

How does a nuclear medicine scan work?

Nuclear scans use radioactive substances to see structures and functions inside your body. They use a special camera that detects radioactivity. Before the test, you receive a small amount of radioactive material. … Nuclear scans can help doctors diagnose many conditions, including cancers, injuries, and infections.

Can I use my cell phone after radioactive iodine?

You will have to stay in your room for at least 1 to 2 hours after your treatment. You can use your cell phone or watch TV to help pass the time. You won’t be able to have visitors during this time. You may not have any side effects from the treatment right after you get it, but you may have side effects later.

What is nuclear scintigraphy used for?

Nuclear Scintigraphy. Nuclear scintigraphy uses very small, tracer amounts of radioactive molecules to diagnose diseases involving bone, soft tissues and vessels. We can attach these molecules to agents that bind to bone lesions, soft tissue tumors and sites of infection.

Can nuclear medicine make you sick?

There are no known long-term adverse effects from such low-dose exposure. Some potential side effects that might occur include: Bleeding, soreness or swelling may develop at the injection site and allergic reactions to the radiopharmaceutical may occur, but are extremely rare.

What is a nuclear medicine whole body scan?

A Whole Body Scan (WBS) is a scan performed in nuclear medicine. This scan is done to check for the return or spread of thyroid cancer cells.

How is scintigraphy done?

Scintigraphy (from Latin scintilla, “spark”), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by external detectors (gamma cameras …

How do I read my bone scan results?

Understanding Bone Density Test ResultsA T-score of -1.0 or above is normal bone density. Examples are 0.9, 0 and -0.9.A T-score between -1.0 and -2.5 means you have low bone density or osteopenia. … A T-score of -2.5 or below is a diagnosis of osteoporosis. … The lower a person’s T-score, the lower the bone density.

What does a positive bone scan mean?

Your doctor may order a bone scan if you have unexplained skeletal pain, a bone infection or a bone injury that can’t be seen on a standard X-ray. A bone scan can also be an important tool for detecting cancer that has spread (metastasized) to the bone from the tumor’s original location, such as the breast or prostate.

Are nuclear bone scans safe?

A bone scan carries no greater risk than conventional X-rays. The tracers in the radioactive substance used in a bone scan produce very little radiation exposure. The risk of having an allergic reaction to the tracers is low. However, the test may be unsafe for pregnant or breastfeeding women.

What should I avoid after a nuclear stress test?

Do not eat chocolate or drink coffee, tea, soda, colas or other caffeinated beverages such Mountain Dew or energy drinks. If you are unsure, do not drink it. See the table below for more details. The table below also has a list of medications containing caffeine.

Does an MRI use radiation?

Because radiation is not used, there is no risk of exposure to radiation during an MRI procedure. However, due to the use of the strong magnet, MRI cannot be performed on patients with: Implanted pacemakers.

How long does it take to get the results of a bone scan?

How soon will the scan results be available? A radiologist will interpret the images, write a report, and deliver the results to your doctor via the internal computer system. This process usually takes less than 24 hours.

Why is nuclear medicine used for the musculoskeletal system?

A Bone Scan is one of many Nuclear Medicine imaging procedures. Bone scanning allows determination of small fractures, infections, loose prosthetics, and metastatic disease of the skeleton. … This is necessary to obtain the best quality images of the skeletal system.

Is a bone scan the same as an MRI?

A bone scan is just one imaging tool used to identify bone conditions in an individual. MRIs are also effective in producing internal images of the body that can be used to make proper diagnoses.
