Radiographic Technique Flashcards
Forearm Routine
AP
Lateral
The study of bones
Osteology
Hand Routine
PA
Fan Lateral
Oblique
Chest routine
PA
Lateral
(Supine and LLD if can’t stand)
Elbow Routine
AP
Lateral
AP Oblique-medial rotation
AP Oblique-lateral rotation
3 sections of the chest
- bony thorax
- respiratory system
- mediatinum
Abdomen Routine
Supine abdomen
Upright (AP) abdomen
Why do we do the 4 different radial head views?
To make sure radius is rotating properly around the ulna
Which carpal bone is most commonly broken?
Scaphoid
Why do we use ulnar deviation?
- prevents foreshortening of the bone
- opens adjacent carpal interspaces
Classifications of Joints
According to Structure: fibrous, cartilaginous, synovial
According to function: immovable, slightly moveable, freely moveable
Special Requests for the hand
- Extension Lateral
- Ball catcher’s
- AP
Why do we take a lordotic chest in special request?
If they suspect the person has TB or a pathology in the apices of the lungs
Smith’s fracture
Transverse fracture of distal radius with anterior displacement of distal fragment
Shoulder Routine
AP
AP Oblique-glenoid cavity
Lateral-Scapular Y
Superoinferior Axial
Why do we take an AP of the hand?
- hand is deformed
- object sticking out
- bone broken, hand stuck
FOOSH
Fall On Outstretched Hand
Wrist Routine
PA
Lateral
PA Oblique
Reasons we do axial projections
- throw anatomy off of what we want to see
- elongate/enlarge bone we want to see
- shoot through the angle of a joint
Adaptive elbow views
- AP elbow: partial flexion
- PA elbow: acute flexion
Why do we take a ballcatcher’s position of the hand?
-arthritis
Thumb Routine
AP
Lateral
Oblique
Acute Abdomen Series
PA chest
AP Abdomen
Supine Abdomen
Colle’s fracture
Transverse fracture of distal radius with posterior displacement of distal radius
1 view abdomen
Supine abdomen
Why do we take an extension lateral of the hand?
For foreign objects or displacement
Scaphoid Routine
PA wrist-ulnar deviation
PA Axial- ulnar deviation
Carpal Bones
Distal row starting at 1st digit:
Trapezium, trapezoid, capitate, hamate
Proximal row starting at 1st digit:
Scaphoid, lunate, triquetrum, pisiform
Humerus Routine
AP upright (or recumbent) Lateral Upright (or recumbent)
Sesamoid Bones
Small, oval bones usually found near joints that are not classed as axial or appendicular
Clavicle Routine
AP
AP Axial
Scapula Routine
AP
Lateral
Divisions of the Skeleton
Axial: skulls, ribs, sternum, vertebral column
Apendicular: upper/lower limbs, shoulder and pelvic girdles
The difference between and male and female pelvis?
Female: angle greater than 90deg, wider
Male: angle less than 90deg, taller and narrower
Pelvis Routine
-AP
Pelvis and Hip Routine
- AP pelvis
- AP hip
- Lateral hip
Rotations of the femur and what anatomy is visualized
External: The neck is foreshortened, The ischial spine and lesser trochanter are visualized
Anatomic: neck is foreshortened, lesser trochanter somewhat visualized
Internal: neck in profile, lesser trochanter not visualized, greater trochanter in profile
Hip routine
- AP
- Lateral (frogleg): mediolateral
What is the Judet view used to visualize?
The acetabular rims
UP: posterior rim
Down: anterior rim
Largest joint space in the body?
Femorotibial joint
Femur Routine
- AP: proximal/distal
- Lateral: proximal/distal (mediolateral)
Knee Routine
- 5deg AP
- Internal oblique
- External Oblique
- 5deg Lateral (mediolateral)
What are weightbearing knees imaged for?
- osteoarthritis
- check for narrowing of joint space
- check for alignment
- evaluation of medial/lateral deformities
IC fossa routine
-PA axial (tunnel view)
Which method do we use for IC fossa?
Camp coventry
Patella routine
-Skyline patella
Tib/Fib routine
- AP
- Lateral (mediolateral)
Another name for calcaneus?
Os calcis
Ankle routine and how joint spaces appear
- AP: open tibiotalar, open medial mortise, closed lateral mortise
- AP oblique (mortise): closed tibiofibular,
- Lateral: open tiobiotalar, fibula over posterior 1/2 of tibia
Calcaneus routine
- Plantodorsal axial: sustentaculum tali in profile medially, open subtalar
- Lateral: open ankle joint, open calcaneocuboidal, open sinus tarsi
Foot routine
- 10deg AP axial : 1st and 2nd cuneiform joint open
- AP oblique w/ medial rotation: sinus tarsi open
- Lateral: open tibiotalar, fibula superimposing posterior 1/2 of tibia
