Computed tomography - CT scan
What is computed tomography?
Computed tomography (CT) is a modern, painless, and non-invasive diagnostic imaging technique that uses X-rays and computer technology to create high-resolution images of the internal structures of the body. It provides detailed information about the brain, spine, internal organs, bones, blood vessels, and soft tissues, which helps doctors diagnose and treat diseases in a timely manner.
Unlike X-rays, which provide a two-dimensional image, CT screening also creates three-dimensional, detailed images sufficient for accurate diagnosis. However, compared to X-rays, computed tomography is characterized by a relatively high level of radiation exposure.
When is computed tomography used?
CT screening is used both in emergency situations and for the diagnosis and monitoring of chronic diseases.
Computed tomography helps doctors detect various diseases and injuries, such as:
- Tumors and benign growths;
- Injuries and fractures;
- Heart disease;
- Diseases of the gastrointestinal tract, such as diverticulitis, Crohn's disease, etc.
- Diseases of the brain;-
- Internal bleeding;
- Infections;
- Vascular diseases, such as aneurysms, thrombosis, or stenosis.
CT screening is also used to monitor various diseases and to assess the effectiveness of treatment in a timely manner. Computed tomography is used:
- To assess changes in tumor size and spread;
- To monitor chronic diseases;
- To assess the condition after surgery;
- To monitor the condition of blood vessels;
- To monitor infections or inflammation.
How is computed tomography performed at New Hospitals?
At New Hospitals, computed tomography is performed on a state-of-the-art, latest-generation 128-slice scanner, which provides the highest image accuracy. The technology is particularly effective in examining small structures and allows for non-invasive assessment of various conditions.
The scanner is equipped with an innovative system that reduces radiation exposure by 60% and increases safety for both patients and medical staff. The procedure is quick and comfortable — the technology is adapted to the individual requirements of patients with different weights and health conditions.
Computed tomography is performed as prescribed by a doctor. The results are quickly processed and sent to the attending physician for a correct diagnosis and treatment planning.
What is contrast material?
Computed tomography can be performed with or without contrast material.
A contrast material is a special liquid used in CT scans to make the structures inside the body appear clearer and more detailed on the image. The contrast agent is usually injected intravenously, although in some cases it is taken orally. It is safe to use, but the patient's health is checked beforehand, especially if they have kidney disease or allergies.
What are the risks of computed tomography?
Like all medical procedures, computed tomography carries certain risks, especially in the case of repeated or unnecessary use.
The main risks are:
- Radiation exposure;
- Allergic reactions or kidney dysfunction due to the contrast agent.
The examination is always prescribed after assessing the patient's individual condition. It is important for the patient to inform the doctor in advance if she is pregnant, she/he has allergies, kidney disease, or diabetes.
