Before the examination begins, the patient lies down on the movable table of the tomograph, which smoothly moves inside the machine. During the scan, it is important to remain still, since this affects the clarity of the images.
The examination is performed in stages: the machine creates a series of layered images, which allow a detailed assessment of the structures of the spine. At certain moments, the patient may be asked to briefly hold their breath to obtain more accurate images.
If magnetic resonance imaging with contrast is performed, standard scanning is carried out first, after which a contrast agent is administered intravenously and the examination is continued. This makes it possible to assess the nature of the changes and their extent more accurately.
The duration of the procedure depends on the scope of the examination and usually is 15–30 minutes, and when contrast is used it may increase to 30–40 minutes.
After the examination is completed, the obtained images are analyzed by a radiologist and a written report is prepared.
