Module 2: Radiologic and Imaging Sciences
(Review) UPDATED Exam Questions and
CORRECT Answers
Axial Plane - CORRECT ANSWER - A horizontal plane that passes through the body or
body part at right angles to the longitudinal axis and divides the body or part into superior and
inferior portions.
Biopsy - CORRECT ANSWER - Removal of a piece of tissue from the body for the
purpose of study; required to confirm a diagnosis.
Computed Tomography (CT) defintion:
What is the basic image production process?
What is the degree of patient contact required? Why? - CORRECT ANSWER - - Provides
cross sectional images of the body
- uses "ionizing radiation"; requires an x-ray source, detectors, and a computer
- "low" patient contact; CT technologist sits at a control panel to operate the scanner's compute;
Good communication skills required
Conscious Sedation - CORRECT ANSWER - An altered state of consciousness achieved
through the administration of certain medications; alleviates pain and often induces amnesia of
the procedure, but the patient can still breathe spontaneously and is capable of responding to
verbal cues.
Contrast - CORRECT ANSWER - Degree of difference between the light and dark areas
of a radiograph
,Coronal Plane - CORRECT ANSWER - A plane that passes vertically through the body or
part from side to side and divides the body or part into anterior and posterior portions.
Cross-Sectional definition:
Which modalities provide cross-sectional imaging? - CORRECT ANSWER - A section
created by passing a plane through an object, usually at right angles to the long axis, but may
also be parallel to the long axis.
- MRI and CT
Diagnostic Medical Sonography (DMS) definition:
What is the basic image production process?
What is the degree of patient contact required? - CORRECT ANSWER - - Uses
"ultrasound" to safely image many organs in the body
- images obtained via "ultrasound waves" transmitted through the patient using a "transducer";
DOES NOT use ionizing radiation
- "close" personal patient contact; great communication skills needed
Digital Radiography - CORRECT ANSWER - The use of a flat-panel detector to record a
radiographic image and render it in digital form without developing or scanning the image
receptor
Dosimetrist - CORRECT ANSWER - A health care professional who determines the
proper amount of radiation to be administered therapeutically.
, Fluoroscopy definition:
What is the basic image production process?
Who performs the helps or procedures? - CORRECT ANSWER - - Dynamic Imaging used
to study "structure and function" of many body systems; Commonly requires administration of
"contrast" media
- uses "ionizing radiation"
- (radiographers) "assists" during procedure; prepares the patient beforehand; provides
instructions after
(Radiologist) performs procedure; procedure requires a physician present
Gamma (scintillation) camera - CORRECT ANSWER - A device used in nuclear medicine
to detect and measure radioactivity emitted from the patient, who has been injected with a
radiopharmaceutical specific to the procedure.
Image receptor (IR) - CORRECT ANSWER - A device that receives the radiation leaving
the patient.
Magnetic resonance imaging (MRI) definition:
What is the basic image production process?
What is the degree of patient contact required? - CORRECT ANSWER - - Provides "cross
sectional imaging"; Used to diagnose a wide variety of diseases and conditions and provides
"excellent soft tissue detail"
- uses "strong magnetic field & RF pulses"; DOES NOT use ionizing radiation
