What does chest X-ray check

Many friends will find that chest X-ray examination is included in every annual physical examination, and chest X-ray is included in almost every physical examination. Therefore, many friends feel very confused and do not know what the chest X-ray checks. In addition, they are also worried about the radiation issues during the chest X-ray examination. So what does a chest X-ray check for?

In fact, chest X-ray examination has a certain purpose. It is mainly used to check whether there are abnormalities in our heart, lungs and diaphragm. It can also successfully detect whether the patient has diseases such as tuberculosis. In addition, chest X-ray examination can also provide a large amount of data support for the doctor's diagnosis. Here I will introduce to you what chest X-ray checks.

What does a chest X-ray check?

Chest X-ray, the full name of which is fluoroscopy, 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 to which X-rays are absorbed 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 chest X-ray: mainly to check whether there are any abnormalities in the heart, diaphragm, and lungs, and most importantly to find out whether the patient has tuberculosis in the body.

Advantages, disadvantages and precautions of chest X-ray:

Advantages: The biggest advantage of perspective is that it can observe the movement and function of organs. Another feature is that the body position, direction and angle can be changed arbitrarily to obtain a three-dimensional concept.

Disadvantages: The image is not as clear as photography, and the ordinary fluorescent screen image cannot be preserved. Because the inspector is close to the machine, protection must be taken.

Precautions

1. Children should be cautious when undergoing chest X-rays

With the continuous improvement of X-ray equipment, the radiation dose is getting smaller and smaller. In addition, the chest X-ray examination is generally less than ten seconds, so the harm to the human body is very small and can be basically ignored. However, since children are at the peak of growth and development, their cells are actively dividing and are much more sensitive than adults. The younger they are, the more sensitive they are, which can cause damage to some of the body's cells. If these damaged cells cannot repair themselves, they will remain in the body like "time bombs". When the immune system is weakened or there are carcinogenic factors, they will begin to replicate crazily and become a cancer lesion.

2. Diseases requiring chest X-ray and protective measures

Chest X-ray is mainly used to examine and diagnose lung diseases, heart size, ribs, pleura, chest wall mediastinum, and bronchi. To reduce the damage of X-rays, patients should not undergo too many chest X-rays, nor should they undergo multiple repeated examinations in a short period of time. In particular, when doing chest X-rays, do not blindly ask the doctor to look longer or more carefully.

Friends, you already know what chest X-ray checks. In fact, chest X-ray examination can be said to provide great basis for doctors' diagnosis and prescription of appropriate medicine. However, chest X-ray examinations still involve a certain amount of radiation, so it is not advisable to have multiple examinations in a short period of time. In addition, you should take certain protective measures and remember not to get too close to the machine, especially children should be more careful during the examination.
