Unlike radiology and ultrasound, both computed tomography (CT) and nuclear
scintigraphy are not readily available. These modalities are limited to referral
hospitals but are becoming much more prevalent in private practice and university
settings. Computed tomography and nuclear scintigraphy are imaging modalities that
can add a tremendous amount of information to the clinical work up and treatment
planning.
Summary
The equine skull and particularly the dental structures with their topographical
anatomy are complicated and can be afflicted by numerous different conditions. In
order to make accurate diagnoses and perform appropriate treatments, many steps
including a thorough clinical examination in addition to diagnostic imaging should be
taken. Radiographic interpretation of dental abnormalities can be very difficult.
Good quality radiographs, knowledge of the normal appearance of the teeth and
knowing what to look for are essential to accurate interpretation. In some cases,
when the clinical situation is complicated, routine radiography is inadequate to
accurately define a problem area. In these cases, computed tomography should be
considered as it has superior resolution without superimposition that can refine the
clinical diagnosis.
