Medical Imaging Study Guide

An X-ray works to create a medical image by:

• using sound waves to create images of the body's interior

• emitting electromagnetic radiation that passes through the body to create images

• using magnetic fields and radio waves to produce detailed images of organs and tissues

• injecting a radioactive substance into the body to highlight areas of interest

An endoscopy works to create a medical image by:

• using sound waves to create images of the inside of the body

• using a magnetic field and radio waves to create detailed images

• inserting a flexible tube with a camera into the body to view internal organs

• using X-rays to create images of the inside of the body

An ultrasound works to create a medical image by:

• using high-frequency sound waves to produce images of structures within the body

• using X-rays to capture images of bones and tissues

• using magnetic fields and radio waves to generate images

• using radioactive substances to visualize organs

Why would a doctor collect a biopsy?

• To diagnose a disease

• To perform surgery

• To prescribe medication

• To conduct a physical examination

An ulcer is a:

• type of infection

• open sore on the skin or mucous membrane

• form of cancer

• blood clot

The part of the body most looked at while using an endoscopy is:

• Stomach

• Heart

• Lungs

• Brain

The main difference between an ultrasound and an X-ray is:

• Ultrasound uses sound waves, while X-ray uses radiation.

• Ultrasound is more expensive than X-ray.

• Ultrasound is used for bones, while X-ray is used for soft tissues.

• Ultrasound provides 3D images, while X-ray provides 2D images.

The type of energy used in an X-ray is:

• Thermal energy

• Kinetic energy

• Nuclear energy

• Electromagnetic energy

The medical imaging device that does not have radiation is:

• X-ray

• CT scan

• MRI

• PET scan

X-rays are most useful for examining which part of the body?

• Bones

• Muscles

• Skin

• Nerves
