This is probably the most common question patients ask before undergoing a CT scan.

As is well known, Computed Tomography is based on the use of X-ray radiation. However, modern CT technology uses this principle in a much more advanced way. During a CT scan, the body is imaged layer by layer, producing very thin slices. The X-ray source rotates continuously, creating a focused beam. In practice, this means that the radiation dose received by the patient is relatively low. Nevertheless, every CT examination involves some level of radiation exposure, which is why CT should be performed only when there are clear medical indications and/or a physician’s referral.

The radiation dose also depends on the CT scanner being used. If the examination is performed on a modern scanner with advanced dose-reduction technology, such as the Philips MX8000 used by the specialists at the MedService Medical Center, the radiation exposure is minimized.

Even under these conditions, the decision to perform a CT scan and the frequency of such examinations should be determined by the treating physician based on the patient’s individual characteristics and medical history.

In many cases, fear of radiation may prevent patients from receiving timely diagnostics. However, it is important to understand that the small risk associated with CT is not comparable to the diagnostic value of the information obtained, which is often essential for establishing an accurate diagnosis and choosing the most effective treatment.
