CAT

It is a diagnostic test that enables visualization of the interior of an area of the body (cranium, neck, thorax, abdomen, bones, etc.) using X-rays and processing the images by computer. It measures the absorption of X-rays by the various tissues. Depending on the type of examination and the pathology to be studied, it may be necessary to administer an intravenous iodinated contrast and/or an oral contrast.

How it is performed?

The patient lies down on a gurney that is inserted into the CT unit where X-rays are generated.

The examination usually lasts a total of about 15 minutes. In that time, the taking of images is not continuous but different image planes are made. The patient can communicate at all times with the technician performing the test.

In cases of abdominal examinations, it is necessary to ingest a litre of special contrast fluid 20 minutes before starting the exploration.

What discomfort can one cause?

Computed tomography is painless.

It does not produce noise or claustrophobia.

In the event of administration of intravenous contrast, the puncture may be uncomfortable.

What risks can one cause?

Computed tomography equipment uses X-rays and is regulated to emit the minimum dose of radiation necessary to obtain the image and the diagnostic benefit.

X-rays can be harmful to the development of a foetus. Therefore, if you think you are or may be pregnant, please let the technician know.

The iodinated contrast is a generally well tolerated substance, although in some cases it can cause allergic reactions that are usually mild and very exceptionally serious. Our centre is prepared to respond to any reaction to the contrast.

If you have ever had an allergic reaction, please let the technician know.

What alternatives are there?

There are other diagnostic imaging techniques (ultrasound, magnetic resonance, radiology, scintigraphy, etc.), each of which is indicated for a specific diagnostic orientation.
