The following images are typical of their group. The
findings were normal when correlated with the clinical evaluations. These examples display
typical patterns seen repeatedly within each group.
The normal appearance of a bone scan changes
notably from the foal to the adult horse. The most apparent feature being the
pronounced uptake in the growth centers. The degree of uptake is relative to
metabolic activity. In the normal adult, the activity in these areas resolves almost
equally to the surrounding bone. The larger more compact or dense bones and the ends
of long bones continue to exhibit greater uptake than the diaphyses. The urinary
bladder and the kidneys are normally visualized as well as a halo of soft tissue
surrounding the entire skeleton.
