What do PET stands for?
Positron Emission Tomography
Name one piece of PPE used in the imaging department?

Name the 3 main parts of a X-Ray Machine>
X-ray tube, collimator, image receptor
Which imaging modality uses strong magnets and radio waves?
MRI
Name one common use of ultrasound in healthcare?
Pregnancy/fetal imaging, heart imaging, or abdominal imaging
What is a radiotracer?
A radioactive substance used to show activity/functions inside the body
What is the purpose of a lead apron?
Protects the body from unnecessary radiation exposure
What type of radiation is used in X-Ray imaging?
Ionizing radiation
Give one advantage of CT over a standard X-ray?
Produces detailed cross-sectional images and shows internal structures more clearly
What is a transducer?
A handheld device that sends and receives ultrasound waves
Name one common radiotracer used in PET scans?
Fluorodeoxyglucose (FDG)
Name one member of the imaging team and their role?
Example: Radiologic technologist—positions patients and performs X-rays
What does ALARA stands for?
As Low As Reasonably Achievable
Name a common Contrast material used in CT scans?
Iodinated/iodine-based contrast
Give one advantage of ultrasound over X-Ray or CT?
No ionizing radiation; real-time imaging
How is a PET scan different from a CT scan?
PET shows metabolic/function activity; CT primarily shows detailed anatomy/structure
What should you do if a patient is pregnant and needs a X-Ray?
Inform the radiologic technologist/radiologist and follow pregnancy/radiation-safety protocols
What are the main reasons to use X-Rays?
To see if there is a broken bones or fractures.
Identify one safety consideration for MRI patients?
Screen carefully for metal, implants, pacemakers, or other MRI contraindications
Name two patients preparations for an abdominal ultrasound?

Give one condition that a PET imaging can help diagnose?
Cancer/tumors; also some brain or heart conditions
Name one career in the imaging technology and a required certification and credential?
