X-Ray, Chest

A chest X-ray test is a very common non-invasive radiology test that produces an image of the chest and the internal organs. To produce a chest X-ray test, the chest is briefly exposed to radiation from an X-ray machine and an image is produced on a film or into a digital computer. Chest X-ray is also referred to as a chest radiograph, chest roentgenogram, or CXR.

Chest tomogram
A chest tomogram is a picture of the chest area created by moving the x-ray machine in one direction while moving the recording film the other way. This method blurs structures in front of and behind the area of the chest being studied. This allows for a more detailed view of a specific level within the chest cavity.

Bacteria are living things that have only one cell. Under a microscope, they look like balls, rods or spirals. They are so small that a line of 1,000 could fit across a pencil eraser. Most bacteria won't hurt you - less than 1 percent makes people sick. Many are helpful. Some bacteria help to digest food, destroy disease-causing cells and give the body needed vitamins. Bacteria are also used in making healthy foods like yogurt and cheese. But infectious bacteria can make you ill. They reproduce quickly in your body. Many give off chemicals called toxins, which can damage tissue and make you sick. Examples of bacteria that cause infections include Streptococcus, Staphylococcus, and E. coli.
