Glabella and EAM
The eye of the scotty dog when imaging the lumbar spine demonstrates which part of anatomy?
Pedicle
This view of the Skull will demonstrate the Petrous pyramids in the lower 1/3 of the orbits
PA Caldwell
When performing an AP lumbar spine, you should center where?

On the Waters view of the Nasal bones where will the CR exit at?
Acanthion
The OML is a line between what 2 anatomical landmarks of the skull?
Orbits and EAM
The neck/collar of the scotty dog when imaging the lumbar spine demonstrates which part of anatomy?
Pars Interarticularis
The AP thoracic spine has the exact same centering as what view that is a technologist's most performed exam.
Chest X-ray
TRUE OR FALSE: You should remove the cervical collar a patient has on to obtain the best image for the Radiologist.
False!
DO NOT manipulate or move head/neck or remove cervical collar.
During any SMV view of the head, this line will be parallel to the IR
IOML
The AML is a line between what 2 anatomical landmarks of the skull?
Acanthion and EAM
Which projection of the spine best demonstrates the extent of a compression fracture?
Lateral View
The view of the Optic Foramina is also commonly called the "three-point landing"
Rheese Method
Which two bony landmarks must be superimposed for an AP open mouth projection?
Front incisors and base of skull
When imaging the zygomatic arches, specifically the oblique inferosuperior tangential view, how much should the patient’s head be rotated? How much should the chin be tilted?
15 degrees for both
The MML is a line between what 2 anatomical landmarks of the skull?
Mentum (Mental Point) and EAM
The SMV view of the sinuses will demonstrate which sinus groups?
Sphenoid, Ethmoid, and Maxillary
This is the only view of the lumbar spine where one can see the infamous "scotty dog" sign
Oblique Lumbar Spine
When imaging the coccyx, it is routinely performed with the patient in a supine position, but it can be done prone.... what must be changed with our positioning if performed prone?
A cephalad angle instead of a caudad angle must be utilized.
When imaging the mandible, specifically the oblique view, how much head rotation is used to demonstrate the body of the mandible?
30-degree rotation
What is the only positioning line that does not connect to the EAM?
GAL - Glabelloalveolar Line
What principle will create more uniform density throughout the thoracic spine?
Anode Heel Effect (Pertaining to the thoracic spine you would want to place the patient, so the more intense aspect of the beam (cathode side) is over the thoracolumbar region of the spine.
FAT CAT
This view of the sinuses will only demonstrate the Frontal and Ethmoid sinus
