Flashcards in PowerPoint Two Deck (45)
A rotation or turning of a body part with movement of the anterior aspect of the part toward the *inside,* or median plane
A rotation or turning of a body part with movement of the anterior aspect of the part toward the *outside,* or away from the median plane
Abduct or abduction
Movement of a part *away* from the central axis of the body or body part
Adduct or adduction
Movement of a part *toward* the central axis of the body or body part
rotation of the forearm so that the palm is down.
rotation of the forearm so that the palm is up (in the anatomic position)
movement forward from a normal position. For example: the mandible.
movement backward or the condition of being drawn back. For example: the mandible.
Lifting, raising, or moving of a part superiorly
letting down or lowering or moving of a part inferiorly
Circular movement of a limb.
The definable standard that radiographs are evaluated by.
Radiographic criteria format
Structures shown, positioning, collimation and CR, exposure criteria and image markers.
"Stuctures shown" from Radiographic Criteria
The anatomic parts and structures visualized on a radiograph
"Postitioning" from Radiographic Criteria
Placement of body part in relationship to IR
and positioning factors important for projection.
"Collimation and CR" from Radiographic Criteria
Decribes how collimation borders should be seen
Location of CR
Center of collimation
"Exposure criteria" from Radiographic Criteria
Describes how technique can be evaluated for optimum exposure of body part
"Image Markers," from Radiographic Criteria
Patient side markers (R or L)
Time markers (as needed)
Essential IR markers
Anatomic side markers (R or L) and patient ID marker.
Basic (routine) projections
Commonly performed projections taken in US and Canada on all average patients who can cooperate fully
Actual routines vary depending on radiologist’s preference and imaging department
Special (Alternative) projections
Sometimes taken in addition to basic projections
Are those projections most commonly taken to better demonstrate specific anatomic parts or certain pathologic conditions
Two positioning rules or principles
Minimum of two projections
Anatomic structures superimposed
Localization of lesions or foreign bodies
Determination of alignment of fractures
Second postioning rule
Minimum of three projections when joints are in prime interest area
AP or PA
Examples of exams needing three projections as basic:
Long bones require two projections as basic. Examples are:
Exceptions to positioning rules are:
Post reduction upper and lower limbs
Pelvis study projection unless a hip injury is suspected.
Refers to process of applying light pressure with fingertips directly on patient to locate landmarks.
How is palpation done?
Gently, patient must be informed of the purpose of it, and permission must be acquired.
How are radiographic imaged viewed?
Whichever way the radiologist chooses, however they are usually viewed with the patient in the anatomic position.
