Computerized Tomography (CT)
CT, which stands for computerized tomography, is a diagnostic technique that uses ionizing radiation to obtain detailed images of specific areas of the body.
These images are obtained differently from the traditional radiology. While the classic X-ray image is the result of the analog transformation of a three-dimensional into two-dimensional reality, in computerized tomography the image undergoes a transformation from analog to digital. During a CT scan, electromagnetic radiation passes through the patient’s body and is transformed into an electrical signal that, after being processed, provides detailed images of the body. If necessary, these images can be synthesized into a three-dimensional model.
CT can be used without and with contrast medium. Contrast media are substances that, introduced into the body (generally intravenously), absorb X-rays more or less intensely based on the area of location, helping emphasize them. Thanks to contrast media, it is possible, for example, to obtain detailed images of the intestine, vessels, brain, abdomen, chest and pelvis.
If a CT scan is performed with contrast medium, administered intravenously, sometimes, immediately after the injection, the patient can feel a slight local burning sensation, a hot flash and a metallic taste in the mouth. These are common sensations that normally last only a few seconds. In fact, the contrast medium is not harmful and only in rare cases it can trigger allergic reactions.
As ionizing radiation are used, it is very important for patients who are pregnant or suspect to be pregnant to communicate their condition to the doctor who may eventually decide to postpone the examination or choose alternative diagnostic procedures.
Unlike magnetic resonance imaging, CT can also be performed in the presence of internal pacemakers or defibrillators.
Who should schedule this appointment?
CT is particularly useful in the study of skeletal structures even if, for small joints (shoulder, elbow, wrist, hands, knee, foot), it is normally preferable to use the magnetic resonance imaging. The use of CT becomes essential to analyze fractures or their outcomes (to evaluate, for example, the position of fracture fragments).
CT is used to visualize the effects of head injuries with particular attention to the presence of any bleeding and, thanks to recent developments, it is increasingly spreading in the evaluation of areas of the body that are difficult to study such as blood vessels, bronchi and internal structures of the heart.
Why choose MediClinic?
The CT scanner used by MediClinic is one of the most advanced equipment currently available, capable of performing every type of scans in order to obtain the most accurate diagnoses possible.
Thanks to the organization of the Diagnostic Imaging Department, the waiting lists are very reduced and it is sometimes possible to book and perform a CT scan on the same day.
Each examination is carried out in absolute safety thanks to the presence of a specialist in anesthesia and resuscitation present who is available for procedures that involve the use of a contrast agent.
