1. MRI

1.1. MRI uses powerful magnets and radio waves. Detailed images produced of soft tissue, versus X-rays and CT scans, which produce images of hard tissues such as bones and teeth.

1.2. Used to examine the brain, spine, joint, abdomen, blood vessels, and pelvis.Detailed images produced of soft tissue, versus X-rays and CT scans, which produce images of hard tissues such as bones and teeth.

1.3. The machine scans the body by turning small magnets on and off. Radio waves are sent into the body. The machine then receives returning radio waves and uses a computer to create pictures of the part of the body being scanned.

2. Bone scan

2.1. Noninvasive medical test used to produce images of the bones that help diagnose and track several types of bone disease. Bone scan is a nuclear imaging test.

2.2. An injection of tracers is administered to the patient and allowed to circulate and be absorbed by the bones. Once absorbed, the patient lies on a table while a machine passes a gamma camera over the body to record the pattern of tracer absorption by the bones. Radiologists look for abnormal bone metabolism on the scan, areas that show up as darker or lighter where tracers have or have not accumulated.

3. x-ray

3.1. how it works: Performed by a machine that sends individual X-ray particles, called photons, through the body.

3.2. Structures that are dense, such as bone, will block most of the X-ray particles and appear white. Metal and contrast media, a special dye used to highlight areas of the body, will appear white. Structures containing air will appear black and muscle, fat, and fluid will appear gray.

3.3. Examines bones, teeth, lungs, breasts, heart, blood vessels, and the digestive tract.

4. CT scan

4.1. series of X-ray views taken from many different angles are combined to produce cross-sectional images of the bones and soft tissues inside your body.

4.2. The X-ray tube rotates around the body. The table slowly moves through the inside of the machine. Each rotation yields several images of thin slices of the body.

4.3. Noninvasive medical test used to produce images of the inside of the body to help diagnose and treat medical conditions.
