Chest X-ray Definition

Conventional radiography is the radiological examination of reference.

Conventional radiography uses an X-ray emitter and a detector image (or radiographic film, now sensors connected to a computer) which is placed between the body segment studied.

During the crossing of the body, the beam intensity is attenuated according to the type of tissue present: they are thicker and more dense, more mitigation will be important.

Increasingly, the devices used techniques involve capture of the image by computer, which allows you to work secondarily images to more accurately keep them as computer files for archiving and transmit images via Intranet or Internet to other physicians.


What is X-ray machine?

In radiology departments or among radiologists, radiology equipment are installed in rooms with thick walls that prevent the passage of radiation.

The radiologist (or radiology technician) is generally placed behind a glass that does not pass the X-ray examination and follows in front of screens or computers that process data and visualize images. 

Chest X-rays may be performed in patients bedridden non-transportable through a mobile device.

Which indications?

The indications for chest radiography are numerous.

The chest radiograph is required for diagnosis, screening and monitoring treatment of lung cancer

Major infections like tuberculosis or lung disease or chronic bronchitis are also part of reference information.

Emergency, it may be prescribed to chest pain fever or not, before a fever without a point of appeal, breathing difficulties particularly related to cardiovascular disease.

In the presence of cough or bloody sputum chest radiography may be indicated.

What are the complications?

The chest X-ray examination is safe.

No complications directly related to the practice of conventional radiography without irradiation significantly lower compared to CT.

During a chest X-ray, radiation is delivered that received naturally for 3 days.

For an X-ray of the abdomen, irradiation is more important since it corresponds to 2 months of natural background radiation.

What results?

The results are available for your doctor

Radiology images are available immediately after the examination, but they must always be analyzed by a radiologist.

It is possible that this analysis takes several hours.

The results are given in the form of a report to be transmitted to the prescriber to review images reproduced on film or on paper plates, and possibly a CD Rom which can be viewed in a computer with special programs for reading radiology.
