Flashcards in Trauma Imaging Review Deck (31)
What is trauma?
-A sudden, unexpected dramatic event
-Incorporates a range of conditions
In trauma imaging, how does one approach the standard projections that are part of the routine protocol for imaging different body parts?
Adaptation (to patient)
What are the differences among the four levels of hospitals?
Level 1 –
Level 2 –
Level 3 –
Level 4 -
***What are the different types of forces associated with trauma imaging?
-Blunt trauma (MVA, collisions, falls & aggravated assault)
-Penetrating trauma (gun shot wounds, stab wounds, impalement injuries, foreign body ingestion & aspiration)
-Explosive trauma (pressure shock waves, high-velocity projectiles & burns)
***What is Principle 1 for trauma imaging?
2 projections 90 degrees to each other with true CR-part-IR alignment
-Angling of CR and IR as needed
-Consider patient’s condition
***What is Principle 2 of trauma imaging?
Entire structure is included on image
-Selection of IR size
-Joint nearest fracture site
What is Principle 3 of trauma imaging?
To maintain safety for patients, healthcare workers and the public
Fracture Terms 9-29:
-Dislocation or luxation
-Bone displaced from joint
***-Subluxation or partial dislocation
-Abnormal shape or alignment
Twisting of a joint resulting in partial rupture or tearing of ligaments w/o dislocation
Break in a bone
Alignment or disalignment describing the relationship of the long axes of fx fragments
Fragmented ends make end-to-end contact
***Lack of apposition or distraction
Fragmented ends are aligned but pulled apart
Fragments overlap and shafts make contact (fracture ends do not)
Loss of alignment of fracture
Direction or angle of apex of fracture
Distal part of distal fragment angled toward midline of body (lateral apex – points away)
Distal part of distal fragment angled away from midline (apex pointed toward midline)
Bone does not break through skin
Portion of bone protrudes through skin
Fracture does not traverse through entire bone
Break is complete and broken into 2 pieces
Torus or Buckle
Buckling of cortex with localized expansion and no complete break in cortex
Fracture on one side only with the other side bent
Near right angle to long axis of bone
Fracture that passes at an oblique angle to long axis of bone
Bone is twisted apart and fracture spirals around long axis of bone
Cast Conversion 30-32:
-Increase kVp by 3-4kV
***Small to medium plaster cast
Increase kVp by 5 to 7 kV
