Abstract:
Objective —To map the equine pelvis using ultrasonography,
validated by use of computed tomography (CT), magnetic resonance imaging (MRI), and
measurements of frozen cadaver slices. Animals —6 ponies and 6 horses. Procedure —Ultrasonographic examination of the
pelvis was performed on 6 clinically normal ponies. Measurements were obtained for imaged structures.
Computed tomography, MRI, and measurements of frozen sections were performed after death and used
to verify measurements. Linear regression determined the degree of correlation between measurements
obtained ultrasonographically and the other modalities. Six clinically normal horses were then examined by use
of ultrasonography. For each structure measured mean, SD, and range were calculated. Results —Data obtained from ponies revealed high
correlations between ultrasonographic findings and those of CT, MRI, and frozen section measurements
( r 2 = 0.97, r 2 = 0.99, and r 2 = 0.99, respectively). Differences between structures measured on
each side of the pelvis were not significant. Variation in size of structures was not associated with weight
of horses. A correlation was not found between weight of horses and ponies and size of structure. Conclusions and Clinical Relevance —Ultrasonography
can be used to accurately measure and evaluate the musculoskeletal structures of the pelvis
of horses. The use of CT, MRI, and measurements of frozen sections provided a means of validating the
ultrasonographic measurements. Reference range values determined in our study can be used to evaluate
horses with suspected pelvic disease. ( Am J Vet
