What's the difference between chest X-ray and chest X-ray?
1, use the function.
Chest radiographs are often used to examine chest diseases (including ribs, thoracic vertebrae, soft tissues, etc. ), chest, lung tissue, mediastinum, heart, etc. Such as pneumonia, tumor, fracture, pneumothorax, cor pulmonale and heart disease.
Chest X-ray mainly depends on whether there are abnormalities in the heart, liver and lungs, and the most important thing is to find tuberculosis.
2. flexibility.
The biggest advantage of chest X-ray is that it can observe the movement and function of organs, and another feature is that it can change the position, direction and angle at will, thus obtaining a three-dimensional concept.
Conventional chest X-ray examination includes orthophoto film (focus film is 200cm away), left orthophoto film (60 ~ 65), right orthophoto film (45 ~ 55) and left orthophoto film. Imaging is relatively simple.
Chest X-rays can certainly observe chest problems, which is beyond doubt.

Matters needing attention
However, because children are at the peak of growth and development, cell division is active, which is much more sensitive than adults, and the younger they are, the more sensitive they are (embryonic tissues are more sensitive to radiation), which will cause some somatic cells to be damaged. If these damaged cells fail to repair themselves (or are abnormal), they will stay in the body, just like a "time bomb". Under the condition of low immunity or the existence of cancer-promoting factors, they will start to replicate wildly and become cancer lesions.
Therefore, the more radiological examinations, the greater the probability of inducing cancer. In the decades after radiological examination, it may induce a far-reaching effect.
