5. What radiology is

5.1. science dealing with radiation finding disease and treatment

6. how xray work

6.1. fractured bones, detect injury or infection, or to locate foreign objects in soft tissue

6.2. is produced when a negatively charged electrode is heated by electricity and electrons are released

7. how pet scan works

7.1. early signs of cancer, heart disease and brain disorders

7.2. works by using a scanning device (a machine with a large hole at its center) to detect photons (subatomic particles) emitted by a radionuclide in the organ or tissue being examined.

8. how ulrasounds work

8.1. diagnosing unexplained pain, swelling and infection, and pregnant women

8.2. A small device called an ultrasound probe is used, which gives off high-frequency sound waves.

9. how mammography works

9.1. breast imaging to detect cancer earlier

9.2. The machine takes x-rays at lower doses than usual x-rays. Because these x-rays don't go through tissue easily, the machine has 2 plates that compress or flatten the breast to spread the tissue apart.
