Prefix - Answer: comes before the root to modify the meaning
Root - Answer: foundation of the word; it's basic meaning
Suffix - Answer: comes after the root to modify the meaning
What does the term "anti" represent in the word antisepsis? - Answer: prefix
What does the term "sepsis" represent in the word antisepsis? - Answer: root
Which of the following is the correct sequence in which a medical term is usually defined? -
Answer: suffix, prefix, root
What is a combining vowel? - Answer: vowel included at the end of the root
What is a combining form? - Answer: refers to the root plus the combining vowel
When do you drop a combining vowel? - Answer: when the suffix begins with a vowel
When do you keep a combining vowel? - Answer: when the suffix begins with a consonant
What is an acronym? - Answer: a new word is formed by taking the first letter of other words,
such as GERD

,What is your imaging goal? - Answer: to get the best image quality with the least amount of
radiation
If you increase ma, will exposure increase or decrease? - Answer: increase
If you increase time, will exposure increase or decrease? - Answer: increase
If you increase kv(penetration) , will exposure increase or decrease? - Answer: increase
If you increase SID (image receptor to the x-ray tube), will exposure increase or decrease? -
Answer: decrease
What is the appropriate exposure to the patient evaluated by in digital imaging? - Answer:
exposure indicators
What is the ideal exposure in mas? - Answer: 30 mas
What is the range for Deviation index? - Answer: -3 through +3
What does the term "brightness" pertain to when it comes to radiologic imaging? - Answer: how
dark/light the image is on a monitor
True or false : brightness is maintained by the computer software so that the image is never too
dark or too light - Answer: true

, What is radiologic contrast? - Answer: differences between two adjacent radiographic shades of
gray
What is high contrast? - Answer: larger differences (black & white)
What is low contrast? - Answer: smaller differences (many similar shades of gray)
When looking at contrast in a radiologic image, what do you aim for? - Answer: lots of shades
of gray in-between the image
What plays the biggest role in contrast? - Answer: kilovoltage (kv)
How does low kilovoltage affect contrast? - Answer: the contrast will be higher
How does high kilovoltage affect contrast? - Answer: the contrast will be lower
When you have high kv, do you want to have a high or low mas to maintain the balance? -
Answer: lower mas
When you have a low kv, do you want to have a high or low mas to maintain the balance? -
Answer: higher mas
Scatter radiation adds an extra layer of gray over recorded image, would this higher or lower the
contrast? - Answer: lower the contrast
What is a radiographic grid? - Answer: device placed between the patient and the IR to absorb
scatter radiation
Will use of a radiographic grid make the contrast higher or lower? - Answer: higher
