Tomography

What is a tomography?
 

A computerized axial tomography, also known as CT, is a diagnostic technique that consists of an examination with ionizing radiation (x-rays), which produces detailed images of axial sections of the body. Instead of obtaining one image, as in conventional x-rays, it obtains multiple images by rotating around the body, thus obtaining a three-dimensional image.

 

Important: 2 contrasted exams should not be carried out in less than 72 hours. If your tomography has a contrast medium, inform the health service personnel if you have received a contrast medium in the last few days.

​
