Questions and CORRECT Answers
Which of the following modalities involve the use of ionizing radiology?
MRI
Sonography
Radiography
Thermograms - CORRECT ANSWER - Radiography
mammography - CORRECT ANSWER - a radiographic examination of the breasts to
detect the presence of tumors
myelography - CORRECT ANSWER - a radiographic study of the spinal cord after the
injection of a contrast medium through a lumbar puncture
angiography - CORRECT ANSWER - x-ray imaging of blood vessels after injection of
contrast material
coronary arteriography - CORRECT ANSWER - radiographic procedure used to study
coronary arteries, used to diagnose atherosclerosis
Education for radiologist? - CORRECT ANSWER - 4 years bachelors, 4 year doctoral
(MD, DO), 4 year residency, 4 year fellowship
Education for RRA? Registered Radiologist Assistant - CORRECT ANSWER - ARRT
certified, bachelor's degree, 1 year of clinicals, complete RRA program, meet educational, ethics,
and exam standards by ARRT.
The generator of the x-ray console includes what? - CORRECT ANSWER - main power,
kVP, mA, timer, rotor exposure switch
, Diagnostic Efficacy - CORRECT ANSWER - Accuracy with which a diagnostic study
reveals the patient's medical condition
Diagnostic Yield - CORRECT ANSWER - amount of clinically useful medical
information about the patient
When you rotor the x-ray button or prepare the x-ray for boost, what occurs? - CORRECT
ANSWER - Contains two different switches.
First switch rotates the anode, preps the x-ray tube for selected exposure factors, cathode heats to
selected mA.
Second switch begins the exposure.
What is an upright bucky or upright cassette holder and what common exams is it used for? -
CORRECT ANSWER - wall mounted, vertical moving cassette used for chest/shoulder
exams. has no gridlines reducing scatter radiation and increasing image quality
What is a photostimulable phosphor plate and what is it commonly referred to as? - CORRECT
ANSWER - the imaging plate is in a light-tight cassette and placed under the body part or
object to be examined. The imaging plate is then run through a special laser scanner, or CR
reader, that reads and converts the image to a digital radiograph. Erasing the imaging is
conditioning.
It is referred to as Computed Radiography.
Label the parts of an xray tube - CORRECT ANSWER -
What is a Positive beam limitation and what is its purpose? - CORRECT ANSWER -
Form of x-ray beam collimation of field size ensuring x-ray exposure field is no larger than
receptor size.
