Definition A chest x-ray is an x-ray of the chest, lungs, heart, large arteries, ribs, and diaphragm. Alternative Names Chest radiography; Serial chest x-ray; X-ray - chest How the test is performed The test is performed in a hospital radiology department or in the health care provider's office by an x-ray technician. Two views are usually taken: one in which the x-rays pass through the chest from the back (posterior-anterior view), and one in which the x-rays pass through the chest from one side to the other ( lateral view). You stand in front of the machine and must hold your breath when the x-ray is taken. How to prepare for the test Inform the health care provider if you are pregnant. Chest x-rays are generally avoided during the first six months of pregnancy. You must wear a hospital gown and remove all jewelry. How the test will feel There is no discomfort. The film plate may feel cold. Why the test is performed Your doctor may order a chest x-ray if you have any of the following symptoms: A...
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.

How the test is performed
The test is performed in a hospital radiology department by an x-ray technician. You will be asked to lie on your back on the x-ray table. You should not move during the test, as this will affect the image quality.
How to prepare for the test

Definition A magnetic resonance imaging (MRI) scan of the chest is a noninvasive imaging method that uses powerful magnets and radio waves to create detailed pictures of the chest (thoracic) area. Unlike x-rays and computed tomographic ( CT ) scans, which use radiation, MRI uses powerful magnets and radio waves. The MRI scanner contains the magnet. The magnetic field produced by an MRI is about 10 thousand times greater than the Earth's. The magnetic field forces hydrogen atoms in the body to line up in a certain way (similar to how the needle on a compass moves when you hold it near a magnet). When radio waves are sent toward the lined-up hydrogen atoms, they bounce back, and a computer records the signal. Different types of tissues send back different signals. Single MRI images are called slices. The images can be stored on a computer or printed on film. One exam produces dozens or sometimes hundreds of images.
