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. ...Read more

Gamma Rays (Definition)

This is light of extremely short wavelengths typically produced either among the stars / in cosmic rays or by radioactive element decay. Gamma rays form the background of normal radiation in which we all live; it is substantially greater than the exposure we get from imaging scans or should get from ...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

What's the difference between an X-ray and a bone scan?

What's the difference between an X-ray and a bone scan?

Both radiation: Nuclear medicine radiation is given internally via IV injection, ingestion, or inhalation for determination of function of organs of body. Isotopes have different half lives and decay at different rates.Ct/xray is external radiation for visualization of anatiomy and pathology. Both contribute to radiation dose. Both are ionizing radiation. Ultrasound and MRI do not involve irradiation. ...Read more

What can a nuclear bone scan show (about my hip bones) that cannot be seen by x-ray?

What can a nuclear bone scan show (about my hip bones) that cannot be seen by x-ray?

Bone scan: A nuclear bone scan may show hairline fractures, bone loss, infection or small tumors not visible on xray. It may also confirm the presence of arthritis that may be suspected on xray. ...Read more

Are there bone tumors that do not show up on X-ray or CT but do show up on bone scan? Can't have MRI (icd)

Are there bone tumors that do not show up on X-ray or CT but do show up on bone scan? Can't have MRI (icd)

Most seen on X-ray: Most primary bone tumors are evident on plain radiographs and ct exam. Mr is usually used to be exact about extent of involvement in soft tissues or marrow. Mr helps surgeon in planning extent of tumor for surgery. Bone scan and pet?Ct are used usually not to make diagnosis of primary bone tumor but extent of spread to other areas of body. Pet/ct is most sensitive and accurate detecting metastases. ...Read more

I had an X-ray of my chest under my left breast and radiologist said There was a dense area and would like a nuclear bone scan. What does this mean?

I had an X-ray of my chest under my left breast  and radiologist said There was a dense area and would like a nuclear bone scan.  What does this mean?

Ask: It is important that you understand why you are having a test done. Nuclear scans are most often done to look at bones for infection or other illnesses. But do ask your doctor what he/she is looking for. All the best. ...Read more

My Mom has pain under left breast by her ribs. She had an X-ray, dr said there was a dense area, wants to do a nuclear bone scan. Costochondritis ?

My Mom has pain under left breast by her ribs.  She had an X-ray, dr said there was a dense area, wants to do a nuclear bone scan. Costochondritis ?

No: Costochondritis does not show up on x-ray. The density is concerning for cancer, and that is what the follow up studies are looking for. Good luck I hope it turns out to be something benign. ...Read more

I am experiencing severe pain in knee and thigh. I have had X-rays a MRI and a bone scan. All points to an Enchrondoma size of lesion is 5.9cm by 3.2cm. Bone scan results say mild uptake in metabolically active lesion?

I am experiencing  severe pain in knee and thigh. I have had X-rays a MRI and a bone scan. All points to an Enchrondoma  size of lesion is 5.9cm by 3.2cm. Bone scan results say mild uptake in metabolically active lesion?

See specialist: Your best option is to see an ORS who is a tumor/ reconstructive surgeon. There are several centers in Canada and many in the U.S.You want a surgeon who has done this surgery before( if needed). They can also determine if this benign bone tumor is the cause of your pain and your options. Best of luck! ...Read more

I was told by an orthopedic oncologist that my tumor was benign without a biopsy, is that possible? I had a bone scan, x-rays, and a CT scan.

I was told by an orthopedic oncologist that my tumor was benign without a biopsy, is that possible? I had a bone scan, x-rays, and a CT scan.

Very much so: Bone tumors are much more characterized by their appearance in imaging studies, and they have correlated with outcomes after exhaustive studies. So when the musculoskeletal oncologist calls it benign, it's petty benign. He should even give you an estimated risk of the tumor changing in any way. ...Read more

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. ...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.

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!

Expert opinions? Which has more radiation: bone scan or ct?

Expert opinions? Which has more radiation: bone scan or ct?

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. ...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
