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. ...Read more

What is the definition or description of: computed tomography?

What is the definition or description of: computed tomography?

Image inside body: Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but often coronal or saggital. ...Read more

Ct Scan (Definition)

Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
