Why is it called CAT scan?

CT scans have nothing to do with cats, except that when people talk about them, they usually say “cat scan” instead of “CT scan.” CT stands for computed tomography, so you can see why people say “CT.” CT scans are a kind of X-ray that gives doctors a much better picture of what’s going on inside the body.

What was before CT scan?

Before computed tomography, tomographic images could be made by radiography by focal plane tomography, representing a single slice of the body on radiographic film. This method was proposed by the Italian radiologist Alessandro Vallebona in the early 1900s.

How long do CT scans last?

The test will take about 30 to 60 minutes. Most of this time is spent getting ready for the scan. The actual test only takes a few minutes.

Are CT scans safe?

At the low doses of radiation a CT scan uses, your risk of developing cancer from it is so small that it can’t be reliably measured. Because of the possibility of an increased risk, however, the American College of Radiology advises that no imaging exam be done unless there is a clear medical benefit.

How much is CT scan cost?

In general, you can expect to see CT scan costs that range from $270 on the very low end to nearly $5,000 on the high end. The cost varies depends on the facility, your location, and factors such as whether you pay in cash or bill your insurance provider.
