Positioning Flashcards
CR for a chest
T7, 7-8” below vertebral prominens (C7), 3-4” below jugular notch
What should be included in a chest x-ray
Lungs from apices to costophrenic angles, 10 ribs above the diaphragm
What is the angle for an AP lordotic chest
15-20 cephalic. Puts clavicles above the apices
CR for supine (KUB) abdomen
Level of iliac crest to show outline of liver, spleen, psoas muscles, kidneys and pubic symphysis
CR for erect abdomen
2” above iliac crest. Include diaphragm to show air fluid levels
CR for a hand
3rd metacarpalphalangeal jt & include 1” of distal forearm
How much is the hand rotated for an oblique hand
Laterally 45 deg with no overlap of body of 3-5 metacarpals
CR for a lateral hand
2nd metacarpalphalangeal jt
CR for finger
Proximal interphalangeal jt
CR for thumb
First metacarpalphalangeal jt to include distal phalanx to trapezium
CR for wrist
Mid-carpals
How much is the wrist obliqued for oblique wrist
45 deg laterally
Why are the fingers curled under for a wrist
Decreases OID between IR and carpals
How many carpals are there and what are they
8 (hand supinates, starting at the bottom by the radius - so long to pinky, heres comes the thumb) scaphoid, lunate, triquetrum, pisiform, hamate, capitate, trapezoid, trapezium
What is the scaphoid view of the wrist
AKA PA/ PA axial with ulnar deviation/ modified stecher method
hand pronated, then evert hand toward ulnar side (medial) to show the scaphoid carpal
can angle the tube 10-15 toward the elbow
What is the gaynor- hart method/ tangential inferosuperior wrist
shows the carpal canal
dorsiflex wrist and rotate internally 10 deg, angle tube 25-30 deg to long axis of the palmar surface of hand, CR 1” distal to base of 3rd metacarpal
How much is the elbow obliqued for medial/lateral oblique elbow
40-45 deg
What is the coyle method/ axial lateromedial elbow
to show the radial head: flex elbow 90 deg, hand pronated, 45 deg angle toward shoulder
to show coronoid process: flex elbow 80 deg, hand pronated, 45 deg angle away from shoulder
CR for AP external rotation of shoulder
1 in below the coracoid process
What does the external rotation of the shoulder show
the greater tubercle
What does the internal rotation of the shoulder show
the lesser tubercle
What is the grashey method/ AP oblique- glenoid cavity
oblique pt 35-45 deg towards side of interest (body of scapula is parallel to IR) CR enters at the scapulohumeral jt
What is the inferosuperior axial shoulder - lawrence method
pt supine with arm abducted 90 deg, hand supinated, CR 25-30 deg medially to axilla
PA oblique of the shoulder- scapular Y lateral and Neer method
pt in 45-60 deg oblique, CR to scapulohumeral jt
Neer method/ supraspinatus outlet: tube 10-15 deg caudal to BD the acromiohumeral space
