PUC Flashcards
Why is the PUC series done?
for biomechanical analysis of upper cervical and occipital condyles
What is the patient position for PUC views?
seated
What is included in the PUC series?
- Palmer lateral
- AP cervical
- Palmer APOM
- nasium
- base posterior (or vertex)
Where does the CR go through for a PUC lateral?
through C1 TVP
What is the distance for PUC lateral?
72”
What is the collimation for PUC lateral?
collimate out eyes laterally but don’t clip spinouses
What are the breathing instructions for PUC lateral?
exhale and hold
How do you set up a PUC AP cervical?
same as routine AP cervical
use 8x10 film
What is the AP cervical done in a PUC series?
- competes series
- checks for pathology
Where should the ID blocker be placed in a PUC APOM?
down
What is the position of the bucky in a PUC APOM?
angled so that it touches the back of the patient’s head and shoulders
What should the CR line up with in a PUC APOM?
bottom of the front teeth to the tip of the mastoid
What is the tube tilt for a PUC APOM?
5-15 degree cephalic
What is the rational for the bucky tilt?
- visualize C1 while keeping the body neutral
- minimize/decrease magnification distortion
How do you figure out the tube tilt for the PUC nasium view?
from the PUC lateral
Where do you measure for a PUC nasium?
from nasion to base of occiput
Where does the CR enter/exit for a PUC nasium?
- enter through nasion
- exit through mastoid tip
Where is the ID blocker placed in PUC nasium?
down
What is the position of the bucky in a PUC nasium?
angled so that it touches the back of the patient’s head and shoulders
What is the tube tilt for a PUC nasium?
caudal tilt determined by lateral film and APL
What is the distance for a PUC base-posterior?
38-42”
What is the bucky tilt for a PUC base-posterior?
45 degrees
What is the bucky tilt supposed to be parallel to for a PUC base-posterior?
atlas-plane line
What is the path of the CR in a PUC base-posterior?
- enters 1” behind chin
- goes in front of EAM
- exits vertex
What is the ideal set-up for the CR in a PUC base-posterior?
perpendicular to the APL
Which PUC views need a filter?
- APOM
- nasium
- base-posterior
Which PUC view is not shot using an 8x10 film?
lateral cervical
