Morphometry of the Thoracic Spine in German Shepherd Dog: A Computed Tomographic Study

Abstract: Computed tomographic images of the thoracic spine of 13 German shepherd dogs were examined in order to determine the thoracic spine morphometry. Examinations were carried out in the transverse plane both intervertebral and mid-vertebral levels of the each thoracic vertebrae. The dorsoventral and interpedicular diameters of the spinal canal, the dorsoventral and transverse diameters of the vertebral body, the dorsoventral and transverse diameters of the spinal cord and also the cross-section area of the spinal … Show more

“…These osteological studies demonstrated that the cranial thoracic vertebral canal diameter was significantly smaller in large breed dogs compared to smaller breeds . In the German shepherd dog, computed tomographic morphometry confirmed marked narrowing of the vertebral canal diameter at T2–4, though morphometric data for other breeds are lacking . In this study the canal area ratio in grade 0 studies indicated that the greatest narrowing between mid‐body and intervertebral levels was at T2–3, and T3–4, which were also the most frequent sites of stenosis in the dogs with primary clinical cranial thoracic spinal stenosis.…”

“…31 In the German shepherd dog, computed tomographic morphometry confirmed marked narrowing of the vertebral canal diameter at T2-4, though morphometric data for other breeds are lacking. 32 In this study the canal area ratio in grade 0 studies indicated that the greatest narrowing between mid-body and intervertebral levels was at T2-3, and T3-4, which were also the most frequent sites of stenosis in the dogs with primary clinical cranial thoracic spinal stenosis. Congenital narrowing of the vertebral canal in the cranial thoracic spine compared to the remainder of the thoracic spine in Molosser-type dog breeds may contribute to segmental stenosis secondary to developmental or acquired changes.…”

“…[2][3][4] CT and MRI images have been used for morphometric linear and angular measurements of the vertebral column and spinal cord in different anatomic planes. [5][6][7][8][9] Study results provide information about the pathogenesis, diagnosis, clinical decision-making, presurgical planning, and prognosis of different disorders affecting the vertebral column and spinal cord; however, little is known about the intra-and interobserver agreement of measurements using different imaging modalities or agreement between CT and MRI derived measurements.…”
