Hi, I had a question. I recently had a whole body Nuclear Medicine bone scan done and the report says "Unremarkable tracer localization is seen in the osseous structures, what does this mean?

Bone scan: The fact that the interpreting md. Stated it appears unremarkable is an indication that your scan is normal. The description about the distribution is the regular venacular describing the normal uptake by the bone (osseous means our bony skeleton) of the material that has been injected. ...Read more

Nuclear Medicine (Definition)

The medical specialty of nuclear medicine involves the use of unsealed radioactive pharmaceuticals that can help image molecular flow throughout the body. The medical use of radiopharmaceuticals also includes the treatment of some cancers and bone pain. Nuclear medicine is separate from diagnostic radiology, which utilizes the use of external (sealed) radioactivity ...Read more

How does nuclear medicine do a bone scan?

How does nuclear medicine do a bone scan?

Tc-99m-MDP Bone Scan: Bone scan often provides an earlier diagnosis and demonstrates more lesions than are found by radiographic procedures. Tc-99m-mdp (methylene diphosphonate) is a bone seeking agent that concentrates in the mineral phase of bone. 2-3 hours after injection, 50%-60% of the activity localizing in bone and the remainder is cleared by the kidneys. F18-naf bone scans are done with pet cameras, r + expensive. ...Read more

Can I have do a bone scan with radiation in the IV if I can't handle IV iodine contrast? I don't want to have the same reaction.

There are: Contrast substances which can be used (or an "alternative" diagnostic test) for people with sensitivity or allergy to Iodine!!!

Your ordering physician MUST be TOLD!

Does bone scan process involve any exposure to radiation as in x ray?

Yes: Both x-ray an isotope for bone scan produce ionizing irradiation. Exposure from isotope of bone scan in adult is about 6 msv. This is similar to some ct scans. The only imaging methods not involving irradiation are ultrasound and magnetic resonance imaging mri. Information from each test is not the same. ...Read more

How to find out how much radiation the patient is exposed to during a bone scan when they inject a dye?

Low end of rad, dose: With a bone scan the radiotracer or isotope is injected intravenously and accumulates after a couple of hours in the bones of the skeleton. The common bone scan with 600 mbq of technetium-99m-mdp has an effective dose of approximately 3.5 msv. This is higher radiation than several routine xrays but is thought not to increase cancer risk in adult patient. ...Read more

Had a bone scan and a CT scan today. Can I still care for my 6 month and 3 year old? Any radiation worry?

Short term: The bone scan uses a small amout of radioactive tracer which may hang around for a short time. Most radiologists recommend no close contact with small children after such a study for 1-2 hours. After that, no worries. ...Read more

I have had four x-rays for my chest, one CT of my abdomenand one bone scan. I am worried whether I have an increased chance of developing cancer from this radiation.

I have had four x-rays for my chest, one CT of my abdomenand one bone scan. I am worried whether I have an increased chance of developing cancer from this radiation.

Don't worry: The amt from the x-rays is almost nothing. Similar to air travel which I assume you don't worry about getting cancer. One ct scan of the abdomen and a bone scan are equivalent to about 7 years of normal life in the us. So same amt of radiation from sun and cosmic rays in that time. Radiation from imaging at those levels has never been shown to cause cancer. ...Read more

Nuclear bone scan: can pepto bismol (bismuth subsalicylate) cause false positive results? False negative results? How likely @ just normal dose pepto (~1000 mg over 2 hours)?

Nuclear bone scan: can pepto bismol (bismuth subsalicylate) cause false positive results? False negative results? How likely @ just normal dose pepto (~1000 mg over 2 hours)?

Yes: Pepto bismol (bismuth subsalicylate) contains bismuth which can block the gamma ray photons which form the bone scan image. As a result bones of the lumbar spine or pelvis can show areas of diminished activity (cold spots) on images acquired from the front (anterior) due to bismuth in the bowel. Routine instructions advise against taking pepto bismol (bismuth subsalicylate) for a week before the bone scan. ...Read more

Is it odd that a nuclear bone scan would not detect 2 rib fractures?

No: Bone scan is a very sensitive way to detect recent bone fractures. However many factors will affect this ability to detect them such as the time interval between the fracture and the scan, the age of the patient, and the location of the fractures. In a young patient, bone metabolism can return to a normal status very quickly. Spect study (tomography) is also very helpful to detect some lesions. ...Read more

CTU and nuclear bone scan report a moderately functionally active right proximal femoral lesion. Associated pain, nausea etc. Should I be worried?

Difficult to know: Needs further detail such as when you have the pain, other associated features etc. I would recommend discussing with the doctor who ordered the test or failing that the GP as if it remains unclear they can examine you to interpret the result and if still not clear they'll be able to refer you to orthopaedics or rheumatology who will give you straight answers on this. All the best. ...Read more

If impacted wisdom tooth is infected, and sends infection + pain to other parts of body, wud this show on nuclear bone scan + wud pain be severe?

Not normally: An infection usually tries to get out by way of the path with least resistance. Expansion in the area is definitely possible but movement more rare that it would spread. Make sure to see a dentist or Oral surgeon soon to evaluate the extent of the infection and the appropriate treatment. ...Read more
