Digital tomosynthesis study demonstrated similar images diagnostic value comparing to the CT.
Horse Genre: Horse Male
Age: 15 years-old
Breed: Belgian Warmblood gelding
History:
The horse was used for combined driving and was presented with a head trauma after receiving a kick from
another horse.
Observations:
On the clinical examination the horse presented bilateral epistaxis, absence of airflow on the right nasal
passage (NP), diminished airflow on the left NP with abnormal respiratory noise and dyspnoea. There was a
bone depression on the axial and right aspects of the nasal bone (NB) midway between the nostrils and the
facial crest. There was no swellings or wounds present. The remainder of the clinical exam and the
neurological examination were unremarkable. A nasopharynx tube was placed on the left NP to ensure
normal airflow.
Diagnosis:
Multiple skull fractures. Radiography and digital tomosynthesis exams were performed for fractures diagnostics and precise localization. The follow-up CT exam (Fig. 1 and 4) completely confirmed previous digital tomosynthesis results (Fig. 2) and Digital tomosynthesis study demonstrated similar images diagnostic value comparing to the CT.
