How should w eposiiton animal for Craniocaudal elbow Xray?
Olecranon should be aligned with the humerus ensuring there is no rotation of the joint
Foam wedges beneath conitralat axialla
flex neck /head away from side fo interest
Elbow craniocaudal centering?
- Primary beam centered midway between humeral condyles
Elbow CC collimaiton?
Include 1/3 along radius:ulna, 1/3humerus proximally and lateral skin edges
Collimated area should not overlap with edges of the plate

Flexed view max flexion 45°
Extended view (110°)
beam centering for elbow mediolateral?
over humeral condyle
Collimation for mediolat elbow?
1/3 of distal and proximal long bones and as tight to lateral skin edges as poss

- Any breed
- At least 1 yo
Two mediolat views minimum 45° and 110° - Permanently and uniquely identified (microchip)
- KC registration available
- On Xray must print: microchip n°, KC reg, Date
What does PCCELA stand for?
Positioning, Collimation, Centering, EXposure, Labeling, Artefact
How to position for VD hip radiograph?
- Extend pelvic limbs and adduct so femurs lie parallel to each other and parallel to casette
- Internally rotate stifles so that patellae are centrally located over trochleae
Centering for VD hip?
on the pubic symphysis / midline be/ the hips
Collimation for VD hips?
lat skin edges, cranially to the iliac crests and caudally to the mid-femur
