Chapter 1 (cont)
Body position where your head is lower than your feet
Trendellenburg
Lowest part of tracheal cartilage
Carina
ALARA
As low as reasonably achievable
Largest carpal bone
Capitate
Medial end of the clavicle is called this
Sternal extremity
Oblique body position in which your right shoulder is against the wall bucky with your anterior side closest to wall bucky
RAO - right anterior oblique
Each half of the diaphragm
Hemidiaphragm
Psoas major
Most commonly fractured carpal bone
Scaphoid
Epicondyles of humerus positioning in AP Proximal Humerus projection with external rotation; internal rotation; neutral rotation
Parallel; perpendicular; 45 degrees to IR
Coning down or making smaller
Collimation
There is an increase in OID, therefore the costophrenic angles will project lower.
Accessory organs of digestive tract
Liver, gallbladder, pancreas, and spleen
Visualized carpal bone during a PA Wrist with Radial Deviation
Hamate
Greater tubercle is lateral in profile in this rotation
External rotation
Bones that have peculiar shapes - vertebrae, facial bones, & pelvic bones
Irregular bone
What is the minimum number of ribs that should be visualized in an adult PA CXR?
10 rib pairs
Location of kidneys in peritoneum
Retroperitoneal
Positioning of epicondyles to IR for AP forearm; lateral forearm
Parallel to IR; perpendicular to IR
Why is arm abducted in AP Scapula projection
Moves scapula away from thoracic cavity
Average body type; very thin; large; slender
Sthenic; asthenic; hypersthenic; hyposthenic
Reasons for CXR to be taken erect
Prevents engorgement of vessels, easier to visualize air and fluid levels, and the diaphragm can move further down
AP Abdomen Criteria
Symphysis pubis visible, kidneys and lower liver margin included, no rotation (spinous processes equally centered), and no motion
Increase of kVp for small-medium plaster cast; large plaster cast; fiberglass cast
From 5kVp to 7kVp; from 8kVp to 10kVp; from 3kVp to 4kVp
Shoulder projection that best demonstrates intertubercular groove
Fisk - Tangential projection
