This part of the "scotty dog" is seen on a correctly positioned oblique lumbar spine.
What is the eye?
100
This view demonstrates vertical patellar fractures and the femoropatellar articulation.
What is the tangential patella view?
100
AP stress studies of the ankle can performed for these situations.
What are inversion or eversion injuries and to demonstrate ligament tear?
100
CR is angled here for an AP projection of the sacrum
What is 15* cephalic and 2" superior to pubis symphsis?
200
These are demonstrated on the oblique C-spine.
What are intervertebral foramina?
200
This will demonstrate the right lumbosacral zygapophyseal articulation.
What is 25-30* LAO?
200
This bony landmark is in the same tranverse plane as the symphysis.
What is the greater trochanter?
200
Trimalleolar fracture includes these three fractures.
What are fractures of the lateral malleolus, medial malleolus, and posterior tibia?
200
This is the amount of obliquity that the body should be rotated for an anterior oblique projection of the sacroiliac joints.
What is 30 degrees?
300
These being the furthest from the film are best demonstrated on the AP oblique.
What are the intervertebral foramina?
300
This will demonstrate the right lumbosacral zygapophyseal articulations.
What is 25-30* LAO?
300
When perfroming an AP axial or "frog leg" projection of the femoral neck, the patient must be in a supine position with the affected thigh in this postion.
What is the leg abducted 40* from vertical?
300
These are visulized on the medial oblique projection.
What are the talofibular joint, talotibial joint, and plantar surface should be vertical?
300
These make up the acetabulum.
What are the ilium, ischium, an pubis?
400
These vertebral structures have bifid tips.
What is spinous process of the cervical vertebrae?
400
The left zygapophyseal articulatoins of the lumbar vertebrae are best demonstrated in this position.
What is LPO?
400
Inferior tip of the patella.
What is the apex?
400
The lower leg should be rotated this much to properly demonstrate the mortise view of the ankle.
What is 20 degrees internal?
400
This is probably the reason for some foreshortening in the right iliac wing on an AP pelvis view.
What is left side rotation?
500
This is referred to the axis.
What is C2?
500
These are the short thick processes that project posteriorly from the vertebral body.
What are pedicles?
500
This is the forward slipping of one vertebra on the one below.
What is spondylolisthesis?
500
This projection of the foot should demonstrate metatarsal nearly superimposed on each other.
What is a lateral?
500
This is what is demonstrated on an 25* LPO postion with the CR entering 1" medial to the elevated ASIA.
