Q

What is done differently for PUC?

A
  1. patient seated for all views
  2. patient is in neutral position (not “after class slump” or rigid posture)
  3. patient head tilt stays, rotation does not
2
Q

PUC series in order

A
palmer lateral
AP
palmer APOM
nasium
base posterior/vertex
3
Q

SID PUC lateral cervical

A

72”

4
Q

film size PUC lateral cervical

A

10x12

5
Q

CR position PUC lateral cervical

A

through C1 TVP

6
Q

collimation PUC lateral cervical

A

collimate out eyes, but not C7 spinous process

7
Q

AP PUC cervical

A

same as routine cervical

8
Q

ID blocker for PUC APOM

A

down

9
Q

bucky placement for APOM

A

touching back fo the head and shoulder, patient is in neutral position

10
Q

tube tilt for APOM

A

5-15 degree cephalic tube tilt

11
Q

filter for APOM

A

filter out orbits

12
Q

why do we need a bucky tilt?

A

to visualize C1 while maintaining body’s neutrl position

minimize magnification distortion

13
Q

nasium SID

A

40”

14
Q

film size for nasium

A

8x10

15
Q

collimation for nasium

A

8x10

16
Q

ID blocker location for nasium

A

down

17
Q

bucky position for nasium

A

touching the back of the head and shoulders, patient is in neutral position

18
Q

tube tilt for nasium

A

caudal tilt determined by the lateral film and atlas plane line

19
Q

CR nasium

A

exiting the inferior tips of the mastoids

20
Q

filters for nasium

A

filter eyes

21
Q

base posterior SID

A

38-42”

22
Q

film size base poisterior

A

8x10

23
Q

collimation for base posterior

A

8x10 ID blocker down

24
Q

bucky placement for base posterior

A

bucky at 45 degrees

25
Q

patient positioning for base posterior

A

vertex to center of bucky

26
Q

CR base posterior

A

enters 1” behind chin, goes in front of EAM, exits vertex

27
Q

filter for base posterior

A

filter eyes

28
Q

which positions need a slight bucky tilt?

A

APOM

nasium

29
Q

which positions need a 45 degree bucky tilt?

A

BP/vertex

30
Q

which positions need a tube tilt? What kind of tube tilt?

A

AP- 15 cephalic
APOM 5-15 cephalic
nasium- 5-20 caudal

31
Q

which films do you filter out orbits?

A

APOM
nasium
BP/vertex

32
Q

differences in PUC lateral compared to routine lateral

A
PUC lateral- 
film size: 10x12
eliminate orbits
CR C1
seated
Routine lateral- 
film size: 8x10
orbits are included
CR C4
seated/standing
33
Q

ID blocker placement

A

Up: lateral, AP
down: APOM, nasium, BP/vertex

34
Q

PUC APOM vs APOM

A
PUC-
slight bucky tilt
seated
filterout orbits
don't collimate orbits
5-15 cephalic tube tilt
don't manipulate patient
APOM-
no bucky tilt
seated/standing
no orbit filter
collimate eyes
no tube tilt
manipulate to perfect image
35
Q

why do we take AP cervical in a PUC series?

A

opposing view of the lateral

check for pathology
