What is the difference between a chest X-ray and a chest radiograph

When people have adverse reactions such as persistent coughing, they often suspect that there is a problem with the lungs. Examinations of the lungs, heart and other parts often require chest X-rays or chest radiography for diagnosis. But what is the difference between a chest X-ray and a chest X-ray? In what situations are chest X-rays suitable and in what situations are chest radiography suitable? Let’s take a closer look at it together.

1. The difference between chest X-ray and chest film

A chest X-ray mainly refers to the examination of chest abnormalities through X-ray. The inspection can usually be completed in 0.15 seconds to 0.3 seconds, and the amount of radiation is relatively small. The disadvantages of chest X-rays are that they cannot observe the movement of active organs, are more expensive, and take longer to produce results. It is suitable for observing subtle lesions and dense areas, and can leave permanent records for comparison and consultation during follow-up examinations.

Chest X-ray is a dynamic fluoroscopic observation, which requires X-rays to move across the chest. It usually takes about 5 seconds to observe, but may take up to 10 seconds if there are abnormalities. The amount of radiation exposure of chest X-ray is dozens of times that of chest film.

Chest X-rays have low resolution and poor contrast, and are prone to missing subtle lesions and lesions in thick areas. They also emit a large amount of radiation and cannot leave a permanent record.

From the above, we can see that the advantages of chest X-ray are the shortcomings of chest film, and the advantages of chest film are precisely the shortcomings of chest X-ray. Only by taking advantage of each other's strengths and using them together can their diagnostic role be fully exerted.

2. Prices of chest X-ray and chest films

Chest X-ray is cheaper than chest film. Generally speaking, the price of chest X-ray will not exceed 50 yuan, while the price of chest film will range from 100 to 500 yuan.

3. Chest X-ray or chest film?

Although chest X-rays have higher radiation than chest films, they are still necessary to be combined to examine major lung diseases.

Chest X-ray can only serve as a preliminary diagnosis of cardiopulmonary diseases. When chest X-ray examination finds abnormalities in the heart and lungs, further examination is required by taking a chest X-ray. Chest X-ray can show dynamic effects, but chest film cannot. It can be said that in order to make the examination results more accurate, a combination of the two is needed, so it is impossible to directly say whether chest X-ray or chest film is better.

If it is just a routine check-up, it is recommended to do a chest X-ray, after all, the radiation from chest X-ray is relatively high. However, the price of chest X-ray is relatively expensive. For ordinary people, chest X-ray is also acceptable. After all, with the development of technology, the harm of chest X-ray to adults can be almost ignored.
