Computed Tomography (Definition)

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 ...Read more

Is barium safe with CT scan?

Is barium safe with CT scan?

Yes,: Barium is safe with a CT scan. Dilute barium is often used as oral contrast for a CT. Non dilute barium (for example from a barium enema) will cause an artifact on CT which could obscure much of the anatomy and render the scan useless, so although it is not harmful to you, it could ruin the scan. ...Read more

Is a ct scan of the chest safe?

Is a ct scan of the chest safe?

Perspective: It depends on why you are getting it. Is the risk greater than the benefit? If so, then probably not a good idea to get it. If the potential benefit is greater than the risk of not getting it, then I'd say absolutely, get it done. However, just know, the radiation exposure to a CT is about the same as 200 chest X-rays. ...Read more

What cancers do CT scans cause?

What cancers do CT scans cause?

They don't: Hey Matt! This is a good question and I'm glad to reassure you. A typical CT scan delivers maybe 3mSv, the same as the extra radiation a pilot gets each year. Pilot dose is cumulative and nobody has shown increased cancer in pilots. Up to 20 mSV/year is okay for radiation workers and they don't get extra cancer either. Relax and give yourself a break from worrying. ...Read more
