PART TWO Radiographic Positioning and Related Anatomy
Ventrodorsal
Positioning
Place In: Dorsal recumbency. A trough may be needed-use
clear plastic if possible, and place the device under the
thoracic region, not the area being radiographed. This
minimizes distortion and artifacts.
Head: Gently pull forward. If required, carefully position a
sandbag over the head and neck, taking care not to restrict
breathing.
MEASURE: Caudal aspect of the 13th rib at level of umbilicus (about L2-L3). The area of the liver is generally the widest part.
If interested in another area measure that location.
A
CENTRAL RAY: Canine: Center on midline over caudal aspect of 13th rib at level of umbilicus (L3).
Feline: Two to three fingerbreadths caudal to 13th rib.
Gallbladder

BORDERS: T9 vertebrae (diaphragm) cranially to the greater trochanter caudally to include the coxofemoral joints (pubic
symphysis).
Liver
Pancreas
Right kidney-
Ascending colon
Cecum
Forelimbs: Extend forward with sandbags. If possible, posi-
tion a sandbag just proximal to the elbows over the limbs.
An alternative is either to tie each limb separately or to
place a sandbag over each limb at the carpus and pull
cranially.
Descending
duodenum
Hind Limbs: Keep in a natural position, and place a sandbag
over each limb.

Ventrodorsal-cont'd
Comments and Tips
Place any ID or markers adjacent to the corresponding
side of the abdomen.
Ensure that the body is evenly positioned so that the two
sides of the rib cage appear equidistant.
• Ideally a straight line should be imagined connecting the
point of the nose with the caudal midline.
Ensure that the sternum and spine are superimposed;
image receptor and central ray are perpendicular to both.
CHAPTER 18
Small Animal Abdomen
Expose immediately at the end phase of expiration (this
ensures that the diaphragm is positioned cranially and is
not compressing the abdominal contents).

TECHNICIAN NOTES If radiographs of both the
abdomen and thorax are required, complete both lateral
views before imaging the ventrodorsal views. The position-
ing is the same for the lateral views of the two areas; only
the central ray and borders change.
