Radiographs of the abdomen are taken on inspiration to avoid motion.
True or False |
False |
|
|
Your lateral abdomen radiograph should include from the last rib to the greater trochanter.
True or False |
False |
|
|
When positioning an animal using a v-trough for an abdominal radiograph, the abdomen should be completely in the trough or completely out of the trough.
True or False |
True |
|
|
What should be done to eliminate the animal tilting toward the table on a lateral abdominal radiograph? Choose the best answer.
-pull rear legs caudally and tape -pull front legs cranially and tape -place a foam wedge under the sternum and sponge between femurs -sandbags over the pelvis |
place a foam wedge under the sternum and sponge between femurs
|
|
|
Why is a right lateral view of the abdomen preferred over a left lateral view?
-To allow visualization of the descending colon -to allow better separation of the kidneys -so that the fundus of the stomach is closer to the cassette -so that the pylorus is as far away from the cassette as possible |
to allow better separation of the kidneys
|
|
|
When should an enema be given for a view of the abdomen?
-At least 1 hour before radiology -at least 12 hours before radiology -at least 10 minutes before radiology -24 hours before radiology |
At least 1 hour before radiology
|
|
|
What may help to achieve a long scale of contrast for an abdominal view?
-low kVp and high mAs -high kVp and high mAs -high kVp and low mAs -contrast media |
high kVp and low mAs |
|
|
If the cassette is not directly under the primary x-ray beam, how will the film look?
-The part of the film is not directly under the primary beam is white or unexposed -the part of the film not under the primary beam is black and unexposed -the exposed portion will be distorted -the exposed image will look as if two identical objects are exposed |
The part of the film is not directly under the primary beam is white or unexposed
|
|
|
What should the radiographer do if he or she suspects that the film-screen combination is inappropriate?
keep a stock of every possible screen speed and try them all keep a stock of every possible film speed and try all of them consult the manufacture in the future take radiographs without screens |
consult the manufacture
|
|
|
If the radiographer has developer on his or her hands while loading and unloading the cassette, what artifact might be seen?
white marks nongeneralized black marks generalized image distortion a yellow radiograph |
nongeneralized black marks
|
|
|
Which of the following most commonly cause generalized heavy lines on a radiograph
grid problem roller marks from the processor both a and b are correct none of the above |
both a and b are correct
|
|
|
If a body part to be radiographed has a significant difference in density between its thickest and thinnest parts:
measure and radiograph the thickest part measure and radiograph the thinnest part use the average measurement to determine the area over which to center the x-ray beam take two separate exposures with different measurements |
take two separate exposures with different measurements
|

Both sand and beans (polyester beads) are radiolucent. Therefore sandbags and bean bags do not interfere with the image even it is in the field of interest.
True, both sands and polyester beads are radiolucent Only sandbags are radiolucent Only bean bags made with polyester beads are radiolucent Neither should be in the field interest (both sands and polyester beads are radiopaque). |
Neither should be in the field interest (both sands and polyester beads are radiopaque).
