Radiography Lab Quiz 1

Legally Required to be on radiograph label (4)

Name/address of vet clinic, Patient ID/Name, Date

Info for our radiograph labels (5)

NDSU VTP, Fargo,ND , Anatomy bone, Date, Initials

Lateral views are labeled L or R by the side that is

down on the table

QA/QC tests are performed on (3)

X-ray machine, Dark room, Image receptors

SID for our x-ray machine should =

40 in or 100 cm

SID Marks test is used to

ensure accuracy of SID

Light Field Size test: set collimator to 8 × 10 for example then ? the light field projected onto the table to ensure collimator is ?

measure, accurate

The nine penny test is to ensure

x-ray field is aligned with light field

How to we check our PPE for cracks?

x-ray them

Every individual x-ray machine in specific location needs own ? technique chart

unique

When taking a radiograph, keep as many factor as possible

standardized

One way a technique chart is made

series of trial exposures

For trial exposures, ? test radiographs of ? focused over the ? region

3, abdomen, liver

For trial exposures, kVp is estimated using ? and a ? mAs is used for each radiograph

Sante’s rule, different

When making technique chart, mAs will be ? for all measurements 10cm or less. Measurements over 10cm will be ? that mAs.

R/L Lateral View: Thorax - measure:

caudal border of scapula

R/L Lateral View: Thorax - beam center:

caudal border of scapula, between 5th and 6th ribs, or point of strongest heartbeat

R/L Lateral View: Thorax - cranial boundary

thoracic inlet

R/L Lateral View: Thorax - caudal boundary

L1, 1-2 cm past last rib

For Thorax, take exposure at peak of

inspiration

Signs of good positioning for lateral thorax (3)

rib heads superimposed, intervertebral foramina same size, transverse processes superimposed

VD and DV Thorax - measure:

caudal border of scapula

VD and DV Thorax - bean center:

midline at caudal border of scapula, between 5th and 6th ribs

VD and DV Thorax - cranial boundary

thoracic inlet

VD and DV Thorax - caudal boundary

L1, 1-2 cm past last rib

Signs of good positioning for VD/DV Thorax

sternum/spine superimposed, spinous processes center over vertebral bodies, two sides of ribcage equal in distance

DV view (thorax) has a better visualization of

heart

VD view (thorax) has better visualization of (4)

lung tissue, ventral pulmonary fields, caudal vena cava, mediastinum

When measuring VHS, measure height from

carina to apex

When measuring VHS, measure width from

widest area

When measuring VHS, transfer measurements to vertebrae, starting at the ? edge of ?

cranial, T4

When radiographing long bones, include

joint above and below

For lateral view of a long bone, the affected limb is

down on the table

Common views for long bones (3)

Lateral, CrCd, DP

Common Joint views

Lateral, CrCd

Lateral Elbow Joint - measure:

thickest part of elbow at distal humerus

Lateral Elbow Joint - beam center:

distal humeral condyles

Used a Flexed Lateral view of the elbow for evaluation of

elbow dysplasia

Lateral Radius/Ulna - measure:

distal humerus

Lateral Carpus/Digits - measure:

middle of carpus

Lateral Carpus/Digits - beam center:

distal row of carpal bones

DP Carpus/Digits - measure:

distal row of carpal bones

To extend a limb, push from

behind the elbow

Lateral Abdominal - measure:

caudal aspect of the 13th rib

Lateral Abdominal - beam center for dogs:

over caudal aspect of 13th rib (at L2-3)

Lateral Abdominal - beam center for cats:

2-3 fingers below 13th rib

Lateral Abdominal - cranial border:

caudal aspect of T7

Lateral Abdominal - Caudal border:

greater trochanter

For lateral abdominal positioning, elevate with a foam pad under the

sternum

VD/DV Abdominal - measure:

caudal aspect of 13th rib at level of umbilicus

VD/DV Abdominal - beam center for dogs:

midline over caudal aspect of 13th rib at level of umbilicus (L3)

VD/DV Abdominal - beam center for cats:

midline, 2-3 fingers caudal to 13th rib

VD/DV Abdominal - cranial border

T9, diaphragm

VD/DV Abdominal - caudal border

greater trochanter

Take abdominal radiograph at peak of

expiration
