What is CT?
Computed tomography (CT) is a cross-section imaging technique of examination of the structure of internal organs, soft tissues, bones and blood vessels using roentgen radiation. Unlike X-ray, which allows taking a picture in only one projection, during CT, the area under examination is scanned by sensors from all sides at different angles. The resulting images are processed by a computer and converted into high-definition 3D images.
During CT, a person receives a small dose of radiation, so scanning is performed only as directed by a doctor. However, the potential harm of computed tomography for health is much less than the benefits obtained, since the examination allows to identify many diseases at an early stage and to start treatment on time, significantly increasing the chances of recovery.
How is computed tomography performed?
2-4 hours before the computed tomography procedure, it is necessary to refrain from eating and drinking. Immediately before the examination, it is necessary to remove all metal jewelry (earrings, watches, rings) and clothing that contains metal elements.
Stages of CT:
- The patient lies down on the conveyor table, and the doctor helps him/her to take the correct posture to ensure the accuracy of the examination. If intravenous contrast CT is performed, the patient is given an intravenous contrast agent.
- After turning on the tomograph, the table moves to the frame of the machine and scanning begins. During the examination, the patient may be asked to hold his/her breath for a short time or not to swallow. The CT procedure takes an average of 5-30 minutes depending on the type of examination. The received radiation dose during computed tomography does not pose a threat to health, since the use of the modern SOMATOM go.Up tomograph allows to reduce the radiation exposure due to fast scanning.
- After the completion of the computed tomography procedure, the doctor prepares a conclusion and gives it to the patient along with the recording of the obtained image on the information carrier.
