Multislice CT is a technology used in computed tomography (CT) scans. While traditional CT scans are generally used to obtain a single slice, multislice CT is used to obtain multiple slices at the same time. This provides faster scanning times and higher resolution.
Tomography (CT) examination is a diagnostic method known to everyone and it is the imaging of the body at the desired thickness (1 cm or 1 mm) by using X-rays.
Classical Tomography devices scan the body slice by slice, the table on which the patient lies during the shooting moves as much as the thickness of the section to be examined. When the table stops, an image is taken with the X-ray given to the area to be examined, the table moves again and the same process is repeated.
In “Spiral Tomography”, the area to be examined is scanned as a whole in a very short time. Here, the table is in constant motion and the X-ray tube rotates around the patient in a spiral fashion and takes images. In spiral tomography, this process is completed in approximately 15 seconds, and the images taken are collected in the memory of the device and are ready to be examined whenever desired.
Chest (Thorax) and Abdominal (Abdominal) organs are the organs that are displaced by respiratory movements. During tomographic examinations of these regions, the patient holds his breath so that the images can be taken clearly; However, this breath holding process may not be at the same depth every time, and the patient may not always be able to hold the breath in accordance with the device (classical tomography).
Therefore, in the sections taken depending on the patient’s breathing depth; (As seen in the picture above) the section on the right of the picture is not a continuation of the one on the left, and the round white lung lesion has been omitted due to the patient not breathing regularly. Therefore, the next section taken may not actually be a continuation of the previous lung area, and if there is a lesion there, it will be missed by the classical tomography method.
However, in the “Spiral Method” e.g. If the lung is being scanned, the patient takes a deep breath and holds his breath; The device completes the examination very quickly, within 15 seconds, before you start breathing again. Since the lung is scanned in its entirety, there is no section skipping. Spiral Tomography, which has many advantages over Classical Tomography, is of indisputable diagnostic value, especially in Thorax and Abdominal scans.
