Rad-104: Forearm Procedures

AP forearm positioning

elbow extended with supinate hand

upper limb in the same plane

humerus epicondyle equidistant from IR

long axis of forearm aligned parallel

CR of the AP forearm

perpendicular to IR

enters patient at midpoint of forearm

collimation of AP forearm

includes wrist to distal humerus

all surrounding soft tissue

AP forearm imaging criteria

includes wrist to distal humerus

radial head, neck, and tuberosity slightly superimposed on proximal ulna

no elongation or foreshortening of humerus epicondyle

elbow joint partially open

density similar ton proximal and distal portions of forearm

density and contrast adequate to make bony trabeculation and soft tissue visible

positioning of lateral forearm

entire upper limb in plane with forearm resting on ulnar surface (lateromedial projection)

elbow flexed 90 degrees

ulnar and radius styloid process superimposed

long axis aligned parallel with IR

CR of lateral forearm

directed perpendicular to IR

enters at midpoint of forearm

collimation of lateral forearm

includes wrist to distal humerus and surrounding soft tissue

lateral forearm criteria

wrist to distal humerus demonstrated

superimposition of humeral epicondyle

superimposition of distal ends of radius and ulna

elbow flexed 90 degrees

radial head superimposed over coronoid process

radial tuberosity pointing anteriorly

density and contrast adequate to make bony contrast trabeculation and soft tissue visible
