Computed tomography, also popularly known as CT tomography (computed tomography), is an advanced diagnostic method that enables accurate imaging of internal body structures. In this article, we will discuss what this test looks like, what are the indications for its performance, and what impact it may have on the patient’s body.
What does a ct scan look like?
A tomograph examination involves obtaining a series of X-ray images of cross-sections of the patient’s body. This device consists of a ring with a detector and a moving source of X-rays. The patient lies on a table that moves through the ring, and X-rays are recorded during this process. The received data is then processed by computer and creates a three-dimensional image of the examined area.
What does preparation for computed tomography look like?
Preparation for tomography depends on the type of examination and the area of the body examined. In some cases, it may be necessary to inject intravenous contrast, which may require several hours of restriction of food intake in advance. It is also worth informing your doctor about any allergies to medications or contrast to avoid possible complications.
What are the indications for computed tomography?
Computed tomography is often used in the diagnosis of various diseases and pathological conditions. Indications for this examination may include suspicion of cancer, injuries, inflammation, cardiovascular diseases, as well as assessment of the condition of internal organs such as the brain, lungs, liver or pancreas. The doctor decides to order a CT scan based on clinical symptoms and other available information.
What effect does computed tomography have on the body?
During a tomography examination, the patient is exposed to X-ray radiation. The dose of this radiation is adjusted to the type of examination and the area of the body that is imaged. Although this is relatively low radiation, there is some risk of its effects on the body, especially in the case of frequent examinations. Therefore, it is always important to use tomography only when medically justified and to minimize the radiation dose to the minimum necessary.
Computed tomography is one of the most important diagnostic tools in medicine. Thanks to it, it is possible to detect many diseases at an early stage, which increases the chances of effective treatment. Nevertheless, you should remember to approach this test responsibly and use it only when necessary. If in doubt, consult your doctor.
How often can it be performed?
The frequency of computed tomography depends on the individual patient’s situation and the doctor’s recommendations. There is no universal rule regarding the frequency of this examination. The final decision depends on the type of disease, course of treatment and other factors. Your doctor will be the appropriate person to assess the need for a repeat CT scan.
