Computerized axial tomography or CT, also known as a scanner, is an imaging test that allows, through X-rays, to obtain radiographic images of the area inside the body in which said exploration is being carried out.
This test, contrary to what can happen with Magnetic Resonance, does not give the sensation of claustrophobia, so it is important to know how to prepare for a CT scan since the patient is not inside a closed space, nor are unpleasant noises heard. Sometimes the doctor may order the CT scan to be contrast-enhanced. This means that the patient will swallow or be injected with a contrast liquid before the procedure. Although many CT procedures can be carried out without contrast, sometimes doctors need it because through the administration of contrast we can delimit and differentiate vascular structures such as blood vessels and lesions in the parenchyma of organs that otherwise could not be visualized.
Computed axial tomography without contrast
In many of the computerized axial tomography procedures carried out, it is not necessary to use contrast agents. This is because there are areas of our body that can be seen clearly without the need for any treatment.
3D Tomography
New technologies are increasingly present in our daily lives. They evolve faster and faster and in a short time, they become practically indispensable. Experts now believe that the future lies in 3D printing. Although indeed, this technology is not yet very present in our daily lives, it is being introduced little by little, greatly facilitating certain tasks or jobs.
In many countries emerging developments have managed to develop a computer system that enables the creation of exact reproductions of bones and organs, both of people and animals. This technique of reproducing bones and organs in 3D has been made possible thanks to the images obtained through a CAT scan and a Magnetic Resonance Imaging. These images are sent to the 3D printer to make an exact reproduction of the specific bone or organ.
The objective of any company is to create these plastic organs, the same as the original ones, for universities, laboratories, research, medicine and veterinary classes. These plastic organs and bones would thus replace those used up to now, which come from corpses.
