Chest radiography is a common method of X-ray examination used to examine for abnormalities in the heart, liver, and lungs, as well as to detect tuberculosis.

In our physical examinations, we often see chest radiographs. Considering its potential harm to the human body, it has been banned in many countries and China also prohibits its use for children.

Is a chest X-ray required to be fasting? A chest X-ray is not necessary to be fasting because it uses X-rays to create an image on the monitor of the human body. X-rays can penetrate different tissues in the body and present a three-dimensional concept on the screen. Whether you have eaten or not does not affect it.

The human body has density and thickness distinctions, but X-rays can penetrate the human body and reveal the condition of internal organs. Observing for any abnormalities, a black and white image is produced, therefore, food in the stomach does not affect this.

Do you need to take off your clothes for a chest X-ray? No, you don't have to remove your clothes for a chest X-ray. Since X-rays pass through the body, wearing clothes won't affect it.

However, it is possible to take off a thicker coat and if the clothes have metal decorations or fasteners, they should be removed. Metal can affect chest X-ray imaging, so it's best to remove any metal buttons on your clothing as well.

Even some hospitals require women to remove their bras because of the buckles on them. If a doctor mentions this, ladies can go to the bathroom and take off their bras, then put on their coats and proceed with the chest X-ray as there is only metal that could affect the results, not clothing.

How much does a chest X-ray cost? The price for a chest X-ray typically ranges from 10 to 30 yuan, which is determined by different hospitals and regions.

However, in recent years, many physical examinations have gradually begun to replace chest radiography with chest X-rays, especially in student health screenings.

The cost of chest X-rays is generally higher than chest radiography, as the radiation dose involved in chest X-rays is significantly lower and poses less risk to the body. The cost ranges from about 50 to 150 yuan.

Risks of Chest X-ray: The radiation dose from a chest X-ray is 10 times that of a routine chest radiography. Such data makes it seem quite frightening. So, what harm does a chest X-ray pose to our bodies? Chest X-rays use X-rays, which can damage DNA and increase the rate of chromosomal mutations.

X-rays can damage the red blood cell membrane and reduce enzyme activity, thus lowering the body's immunity.

It is worth noting that according to the latest research findings from the International Commission on Radiation Protection, it is estimated that in cities with a population of about 10 million, around 350 people are likely to be exposed to X-rays and develop cancer, leukemia or other genetic diseases.

Precautions for Chest X-ray: The requirements for a chest X-ray are not numerous, and it does not require fasting. However, when undergoing a chest X-ray, it is important to note that one should not carry any metal objects. It is also advisable to avoid wearing clothes with metallic decorations. If the female bra has metal rings, one can remove the bra and wear only an outer garment during the test.

Some reputable hospitals provide gowns for patients undergoing chest X-rays to ensure that external factors do not affect the results.

For expectant parents who are currently trying to conceive, it is advised not to undergo chest radiography, as this may increase the risk of fetal malformations. Pregnant women should absolutely avoid such procedures.

During a chest X-ray, you should also ensure that the gonads and thyroid glands are not exposed to radiation to avoid any potential impact on your health.

Adults should ideally not have chest X-rays more than once a year, while children are not allowed to undergo them.
