midline at level of the ischial tuberosities

27
Q

CHD

A

canine hip dysplasia

28
Q

What do PennHip rads evaluate

Q

proper collimation for mediolateral carpus

A

distal third of radius to proximal third of metacarpals

36
Q

what is a common mistake when getting elbow rads?

A

the assumption that if the paw is flat the elbow should be straight.

proper collimation for lateral skull

A

occipital protuberance at the base of the skull to the tip of the nose

44
Q
