01. How to take high-quality X-rays?

◆First, the correct position

◆ First, the correct position

Clinicians need to see properly positioned X-rays. Some patients showed me the film, and I saw that the film was crooked, slanted, and not straight. Such a film may affect my judgment.

Picture Second, the image quality is high

I mentioned above that X-rays are the basis and premise of a doctor's diagnosis. In addition, our image quality must be high, that is to say, the equipment we use to take images must be good, and the pixels must be high, so that the pictures we take are clear, and we can see all the structures we want to see clearly on the pictures.

For example, when a doctor performs PKP (vertebroplasty) or when placing a screw, the doctor needs to see the needle insertion point and the needle insertion path of the screw on the image. For example, we need to see the "cat's eye" when driving nails in the lumbar spine. We can only make sure that the nails are in the pedicle by driving the nails into the "cat's eye" completely, so the development of the "cat's eye" is very important.

※Knowledge points

"Cat's eye" refers to the projection of the pedicle in the anteroposterior position.

◆ Third, the level of shooting images should be high

The captured image should not be overexposed or blurred.

02. 3D imaging helps clinical

Finally, I would like to emphasize that the "cat's eye" I mentioned above, on two-dimensional X-rays, doctors rely on experience to determine whether the nail is hit in the pedicle. At this time, if our equipment is more advanced, the diagnostic method A little more, if we can convert two-dimensional images into three-dimensional images, it may not be completely dependent on the doctor's experience.

We can intuitively see whether the nail is in the pedicle or not in the three-dimensional image, which can guide us to accurately insert the needle and guide us to perform a high-quality operation, which can achieve twice the result with half the effort, and the operation will be simple. The more patients, the better the prognosis.

*Individual differences, patients should be subject to hospital diagnosis.
