What is the main role of an interventional radiologist?
To prescribe medication
To use imaging techniques or procedures that make it possible to see internal organs in motion

To provide physical therapy
Radiology: Interventional radiologists perform procedures such as treating tumours, taking organ biopsies, or placing stents by inserting tiny instruments and thin plastic tubes (catheters) into the body via an artery or vein.
True
False
Most diagnostic imaging tests are performed by a certified medical radiation technologist, or an medical lab technologist.
True
False
Who performs specialized diagnostic imaging tests, particularly interventional radiology procedures?
Medical radiation technologist
Ultrasound technologist
Radiologist
Nurse
A radiologist reads, or interprets diagnostic imaging tests to help in diagnosis
True
False
What do radiologists use to diagnose disease and injury?
Blood tests
Medical imaging equipment
Physical therapy
Surgery
Some imaging techniques involve the use of radiation, so safety and protection procedures have no big importance in daily working.
True
False
Radiation can be described as energy or particles from a source that travel through space or other mediums.
True
False
Which of the following are all forms of radiation?
Light, heat, microwaves, and radio waves
Sound, water, and wind
Electricity, magnetism, and gravity
None of the above
Radiation can be either ionizing or non-ionizing, depending on how it affects matter.
True
False
Which of the following is NOT an example of non-ionizing radiation?
Visible light
Heat
X-rays
Radio waves
Non-ionizing radiation includes visible light, heat, radar, microwaves, and radio waves.
True
False
This type of radiation deposits energy in the materials through which it passes, but it does not have sufficient energy to break molecular bonds or remove electrons from atoms. What type of radiation is being described?
(a)
Ionizing radiation (such as x-rays and cosmic rays) is more energetic than non-ionizing radiation.
True
False
When ionizing radiation passes through material, what does it do?
It cools the material
It deposits enough energy to break molecular bonds and displace electrons from atoms
It makes the material glow
It has no effect
The electron displacement creates two electrically charged particles (ions), which may cause changes in living cells of plants, animals, and people. This process is called reionization.
True
False

Gamma rays
X-ray
Microwave

Which type of radiation can damage DNA?
Radio waves
Infrared
Gamma rays
Microwave
Match the following sources to their type of radiation:

Electricity
Non-ionizing
Microwave oven
Non-ionizing
Tanning booth
Ionizing
Medical X-ray

True
False

(a)
Who discovered the ability of certain rays to act on photographic film?
Marie Curie
Wilhelm Conrad Röntgen
Einstein
Rutherford
What type of radiation are X-rays?
Electromagnetic radiation
Sound waves
Mechanical waves
Nuclear radiation
What are the images created by X-rays called?
Photographs
Radiographs
Sonograms
Tomographs
What happens to the x-ray beam during its interaction with the patient before it reaches the x-ray detector?
