Description

The most common diagnostic x-ray examination is a chest x-ray. A chest x-ray produces images of the heart, lungs, airways, blood vessels, spine, and chest bones. X-rays are the common and oldest type of imaging used in medical field. X-rays of the chest are a painless and non-invasive test. The term comes from the Xradiation. It is a type of electromagnetic wave. It has a greater wavelength than Gamma rays and a shorter wavelength than UV rays. There are different kinds of X-rays based on their energy levels: hard X-rays and soft X-rays. Hard X-rays are those with higher photon energies, while soft X-rays are those with lower photon energies. An x-ray examination play important role in the diagnosis and treatment of medical disorders. It uses a small amount of ionizing radiation to create images of the inside body. The purpose of a chest x-ray is to examine the lungs, heart, and chest wall properly for the diagnosis. X-rays are also a form of radiation like light and radio waves. Most materials, including the human body are transparent to X-rays. The x-ray beam is carefully aimed at the area of interest by the technologist.

Typically, a chest x-ray is the initial imaging test done to assist detects symptoms like: problems in breathing a bad or prolonged cough, chest pain, or a fever caused by an injury. A brief burst of radiation is produced by the equipment and goes through the body. Radiation causes an image to be recorded on photographic film or a specific detector. Posterior- Anterior (PA) is the most common and recommended sort of chest X-Ray. The term "posterior - anterior" indicates the direction in which X-Ray rays travel. The patient is instructed to stand with their chest against the film, hold their arms up or to the sides, and move their shoulders forward in order to acquire the image. The patient may next be asked to take a few deep breaths and hold them for a few seconds by the X-ray technician. This approach of holding one's breath generally aids in obtaining a clear sight of the heart and lungs; Anterior-posterior (AP): This kind of chest X-Ray is less common since the image of the heart and mediastinum is less clear and focused. The patient is instructed to stand with their back against the film in order to acquire an AP image. An AP photograph can also be taken with the patient seated or supine on the bed if the patient seems unable to move; Decubitus X-Ray: When the patient is lying on their side, this sort of X-Ray provides a frontal image of the chest. The Decubitus X-Ray can be used to determine the amount of air in the lungs, the presence of free fluid, and the existence of airway obstruction. The x-rays are absorbed differently by different areas of the body. Soft tissue (muscle, fat, and organs) allow more x-rays to flow through them, while dense bone absorbs much of the radiation. As a result, on x-ray bones appear white, soft tissue appears grey, and air appears black. The ribs and spine absorb a lot of the radiation on a chest x-ray and appear white or light grey on the image. Lung tissue absorbs very little radiation, so the image will appear black. Advantages of chest X-ray includes readily available and can be used in practically in any clinical situation. Chest Xray requires fewer resources, uses lower radiation doses and is easier to repeat, and may be done using portable equipment at the point of service reducing the danger of cross-infection during patient transport. The sensitivity of a chest X-ray is primarily determined by two factors: the intensity of the symptoms and the stage of the disease. The majority of x-ray images are digital data that are kept electronically. Patient’s doctor will have easy access to these photos in order to diagnose and treat disease. Chest radiography, like all other types of radiography, uses ionization radiation in the form of X-rays to make an image of the chest.

Conclusion

Many disorders involving the chest wall, including its bones, as well as tissues housed within the thoracic cavity, such as the lungs, heart, and major vessels, are diagnosed using chest radiography. While chest radiographs are a reasonably inexpensive and safe way to investigate disorders of the chest, there are a number of significant chest conditions that may be linked with a normal chest radiograph, necessitating additional testing. A patient with an acute myocardial infarction, for example, has a perfectly normal chest radiograph. Chest images are frequently used to identify pneumonia and congestive heart failure. In industries where workers are exposed to dust, such as mining, chest radiographs are frequently used to test for any lung related illness according to the job.
