Multislice BT

Tomography ( CT ) examination is a diagnostic method known by everyone, and it is the imaging of the body in desired thicknesses (1 cm or 1 mm) by using X-rays.

Classic Tomography devices scan the body in slices, the table on which the patient lies during shooting moves as much as the thickness of the section to be examined. When the table stops, the 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 as a whole is scanned completely in a very short time. Here, the table is constantly in 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 about 15 seconds, the images taken are collected in the memory of the device and are ready to be examined when desired.

Chest ( Thorax ) and Abdominal ( Abdominal ) organs are organs that change place with respiratory movements. During tomographic examinations of these regions, the patient holds his or her breath so that images can be taken clearly; however, this breath holding process may not be at the same depth each time, and the patient may not always be able to hold the breath in accordance with the device (classical tomography).

Böyle olunca hastanın nefes alma derinliğine bağlı olarak alınan kesitlerde; ( Yukarıdaki resimde görüldüğü gibi ) resmin sağında olan kesit soldakinin devamı olmayıp yuvarlak beyaz renkte olan akciğer lezyonu hastanın düzenli nefes almaması nedeniyle atlanmıştır. Dolayısıyla alınan bir sonraki kesit gerçekte bir önceki akciğer alanının devamı olmayabilir ve orada bir lezyon varsa klasik tomografi yöntemi ile bu atlanmış olur.

However, in the "Spiral Method" eg. if the lung is scanned, the patient takes a deep breath, holds his breath; The device completes the examination very quickly, within 15 seconds, without re-breathing. Since the lung is completely scanned, there is no cross-sectional skipping. Spiral Tomography, which has many advantages over classical tomography, is indisputable in terms of diagnosis, especially in thoracic and abdominal scans.
