What is Total Body CT?
Total Body CT is a diagnostic imaging test, computed tomography, which is performed on the whole body at the same time to observe all the structures of the patient’s body at the same time.
What does it consist of?
Computed Axial Tomography (CT) observation uses X-ray technology to obtain detailed, rotating images of the body’s structures and their function, as well as to identify injuries, fractures and hemorrhages.
It is a non-invasive, fast and precise test that is performed in a large machine, in which the patient remains lying down while the radiation is emitted and the radiologist specialist observes the images in a separate room, using monitors.
Why is it performed?
Total Body CT is a specific type of CT because it is usually performed in case of accidents and medical emergencies, in order to quickly detect possible emergencies to be treated.
It is therefore indicated for the polytraumatized patient, because a rapid diagnosis is required to identify as many pathologies as possible. For example, it is often used in traffic accidents.
In emergency situations, the time of diagnosis and the speed of treatment can make an essential difference in the patient’s prognosis.
Preparation for Total Body CT
Total Body CT is usually performed in emergency situations and therefore no preparation of the patient will be required. However, in cases where it is performed in advance, tolerance tests can be performed on the contrast fluid that may be administered during the test.
On the other hand, tests using radiation are contraindicated in pregnant or breastfeeding women.
The Total Body CT scan analyzes the whole body to detect possible pathologies, wounds and other medical emergencies.
What does the exam feel like?
Total Body CT is a completely painless test. The patient will be asked to enter the machine lying down, usually on his or her back. The patient will be asked to try to remain still during the entire exam, and can return to normal life immediately after the exam.
Significance of abnormal results
The purpose of Total Body CT is to assess the overall condition of the body and bony structures. Therefore, abnormal test results may describe serious fractures and wounds, injuries, bleeding, inflammatory diseases, tumors and cardiac malformations.
Advances
The limitations of CT technology are those of radiology. To visualize in more detail the soft structures of the body such as the internal pelvic organs, brain and joints, ultrasound technology, such as nuclear magnetic resonance, can be used.
