Physical examination is a very important activity in modern life. Physical examination can timely discover disease factors in the body and achieve the advantages of early detection and early treatment. Therefore, most people regard regular physical examination as a kind of protection for the body. There are many items in the physical examination, and almost every one of them is very important. For example, chest X-ray is an advanced physical examination technique. Let’s take a look at what chest X-ray mainly checks?

The full name of chest X-ray examination is fluoroscopy, which is a commonly used X-ray examination method. It uses the penetrating, fluorescent and photographic properties of X-rays to form an image of the human body on the screen. Due to differences in density and thickness of human tissues, when X-rays penetrate different tissues of the human body, the degrees of X-ray absorption vary, so the amount of X-rays reaching the screen varies, forming images with different black and white contrasts, providing a basis for the doctor's diagnosis.

The purpose of a chest X-ray is to check for abnormalities in the heart, liver, and lungs, mainly to detect tuberculosis. Chest X-ray is mainly used to examine and diagnose lung diseases, heart size, ribs, pleura, chest wall mediastinum, and bronchi. More obvious bronchiectasis, emphysema or pulmonary edema, various types of pulmonary tuberculosis, lung tumors; pleura, chest wall and mediastinum; pleural effusion, pneumothorax, mediastinal tumors, heart size, ribs, etc.

Everyone is familiar with what chest X-ray mainly checks: liver function and electrocardiogram. However, many people are completely confused about chest X-ray. Chest X-ray is an important part of physical examination and should not be ignored.

Expert reminder:

How much radiation is emitted during a chest X-ray examination? One chest X-ray is equivalent to taking 10 X-ray examinations. However, a chest X-ray examination usually only takes tens of seconds, so the harm to the human body is very limited. There are few obvious harms from a chest X-ray for adults.

Pregnant women cannot undergo chest X-ray examinations to avoid radiation causing fetal malformations or miscarriage. Women who show signs of pregnancy or are pregnant must be cautious. If they must undergo a radiology examination, it is best to wear anti-radiation clothing to protect their abdomen from radiation. It is better for children to have fewer radiation examinations, and chest X-rays can be used instead of chest X-rays.
