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?

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.

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.

Does bone scan involve any exposure to radiation?

Does bone scan involve any exposure to radiation?

Minimal: There is some radiation exposure as a bone scan involves injecting a radioactive isotope into your blood and then scaning your body to see where the radioactive isotope accumulates.

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.

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!

What exposes the body to more: radiation bone scan or computed tomography?

What exposes the body to more: radiation bone scan or computed tomography?

CT vs bone scan: The amount of CT radiation exposure depends on the type of CT. Average effective radiation dose for bone scan is about 6 mSv. Dose for head CT is 2mSv, for abdomen CT is 8 mSv, and for CT angiogram 16mSv.

Sometimes same dose: Background radiation at sea level: 3 msv per year, denver residents get: 6 msv per year, cross country flight: 0.02 msv, x ray chest: 0.06 msv, ct head: 3 msv, ct chest: 5 msv (equivalent to 100 chest xrays) ct abdomen: 5-10, average bone scan 6.5 msv. Radiation depends on size of patient." radiation affects growing body in children more than adults. Doses to children are much less.

Does a bone scan use radiation?

Does a bone scan use radiation?

Yes: It is a nuclrear medicine study that uses a small amount of radiation similar to xrays. The amount usrd is not in a range that is harmful or should be worrisome if the exam is clinically warrented.

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

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.

Is their a lot of radiation with a bone scan (left leg)?

Is their a lot of radiation with a bone scan (left leg)?

No, not really: Bone scan is considered fairly harmless medical procedure. I would not worry about the very small dose of radiation associated with this procedure.

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.

My insurance give huge benefit for annual checkup. Considering DEXA Bone scan L-S Spine + Hips. I am 38. Too early? How much radiation?

My insurance give huge benefit for annual checkup. Considering DEXA Bone scan L-S Spine + Hips. I am 38. Too early? How much radiation?

Somewhat early: It's somewhat early but not going to hurt anything to have it done. The radiation is low dose, less than a chest x-ray.

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

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.

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.

Does a person with a prostate cancer gleason score of 9 have any shot? Dr states hormone rherapy and possible radiation depend on ct/mri & bone scan

Does a person with a prostate cancer gleason score of 9 have any shot? Dr states hormone rherapy and possible radiation depend on ct/mri & bone scan

It depends on Stage: Hormonal therapy using a shot is commonly used but only for Cancer of stages 3 and or 4 of prostate Cancer. For stage 1 or 2 there is local therapy (surgery or radiotherapy) are considered adequate.

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.
