Computed Tomography (CT) and Technical Information

It is a radiological diagnosis method for creating a cross-sectional image (front to back-coronal; top to bottom-axial; right to left-sagittal) of the examined area of the body using X-ray. During the examination, the patient lies on the table of the computed tomography device without moving. The table is inserted into the opening called "gantry" of the device by manual or remote control. The device is connected to a computer. While the X-ray source performs a 360-degree rotation around the patient to be examined, the data obtained by detecting the part of the x-ray beam that passes through the body is processed by a computer by detectors lined up along the hollow or "gantry". As a result, cross-sectional images of the tissues are created one after the other. The created images can be viewed on the computer screen. In addition, images can be transferred to film or stored on an optical disc to be brought back to the computer screen when necessary. Computed tomography has some advantages over other x-ray examinations. It shows the shape and placement of organs, soft tissues and bones very clearly. In addition, CT examinations help physicians in the differential diagnosis of a simple cyst (a formation in the form of an enclosed sac containing liquid or semi-liquid matter) and solid tumor (tissue mass formed due to rapid proliferation of some cells, ur.), thus enabling better evaluation of diseases. More importantly, CT helps in assessing the extent of cancers by producing images that are much more detailed than direct radiographs. Information about the spread of cancer can guide physicians in the treatment of cancer, helping them decide whether to use chemotherapy, radiotherapy, surgical treatment, or certain combinations of these. Thus, healthy tissues are protected from unnecessary interventions of treatment methods that may have serious side effects, although they have many benefits. CT has made it possible to evaluate many parts of the body, such as the brain, that cannot be demonstrated by direct radiographs. It also enabled the diagnosis of many diseases earlier and more accurately than other imaging methods. Because diseases are better treated when diagnosed early, CT has helped doctors save many lives with these superior features.
