Are scans done with MRI, CAT scan, PET scan, X-ray, or ultrasound machines?

MRI: Magnetic resonance imaging (MRI) uses the body's natural magnetic properties to produce detailed images from any part of the body.

CAT/CT scan: is an upgraded version of an X-ray, which it uses multiple x-rays taken from different angles all around a body. Then uses a computer to create complex cross-sectional images of parts of a body

PET scan: uses radioactive tracers dyes which put into a body(by being swallowed, injecting, etc.). Which is tracked by the PET scanner, creating an image. PET helps to visualize the biochemical changes taking place in the body, such as the metabolism (the process by which cells change food into energy after food is digested and absorbed into the blood) of the heart muscle.

X-ray: when a negatively charged electrode is heated by electricity and electrons are released. Which produces energy that is directed toward an anode at high velocity. Producing an X-ray when the energy collides with the atoms in the metal plate.

Ultrasound: using a small transducer it both transmits sound waves into the body and records the waves that echo back.

Explanation:

I cannot figure out what it is you would like to know. Please think about how your question is worded, and make it clear. In usual medical terminology, static x-rays produce images but are not considered scans, whereas all the others are ‘scans’. CT uses X-rays to make a ‘scanned’ image of internal soft tissues that do not show well on simple static X-ray imaging. MRI uses magnetism and radio ‘waves’, ultrasound uses a version of echolocation, PET uses a radioactive ‘tracer’ compound.
