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.
Depends on body part. Children dose is by weight. For adult patient effective radiation dose in mSv is: bone scan 4.2 mSv CT abdomen 10.0 mSv CT head 2.0 mSv CT chest 8.0 mSv Information obtained is different for these studies. Bone scan can give information about entire skeleton. CT exams are limited to certain portions of body and not whole body.

For visiualization of the internal structure of human body, is it best to have computed tomography?

No. It depends upon what you need to visualize. If you need to see the cerebellum, a ct scan doesn't work as well as an mri. If all you need is to look at the liver or kidneys, then an MRI is overkill compared to an easily accessible ultrasound. Plus, ct scans expose you to (unnecessary) radiation. So ask your family physician and radiologist what's the best way to find the information you need. Read more...
No. It depends on the region of the body that is to be examined. In some instances, computed tomography is the examination of choice, but in other instances MRI or even ultrasound may be superior. The answer for what test is best is complex and depends on the clinical question being asked. Read more...

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

It's complicated.. Ct scans can be done with different settings but in general, a tc bone scan should have less radiation than a ct scan but it depends on what portion of the body the ct scan is performed on. Ct chest? Abdomen? Pelvis? All of the above? 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...
Half lives... I am assuming that you had a technetium bone scan. Technetium has a physical half life of approximately 6 hours. In addition the tracer is excreted in your urine (this relates to biological half life). After a few hours there should be low radiation risk, however, if you are not comfortable with the idea of being near young children immediately after the test you can wait 24 hrs (4 half lives).

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...
Risk is too low to. Accurately measure. Chest xray risk is negligible, 1 abd ct is equal to about 3 years of natural background radiation, and the bone scan equal to about 1.5 years. Please see this site for more details: http://www.Radiologyinfo.Org/en/safety/?Pg=sfty_xray. Read more...
Extremely unlikely. Your cumulative dose is not enough to be concerned about. Read more...
Relax. Radiation workers are allowed up to 20 mSV per year and nobody's shown an increased cancer risk for these folks. Your radiation isn't even this much, once. Be thankful for technology that spots disease early. Best wishes. Read more...

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
