Repeatability and Reproducibility of Measurements of Femoral and Tibial Alignment Using Computed Tomography Multiplanar Reconstructions

Abstract

The CT protocol, as described, was repeatable and reproducible for assessing the femoral and tibial alignment of dogs.

Computation of Femoral Canine Morphometric Parameters in Three‐Dimensional Geometrical Models

“…Computed tomography (CT) and magnetic resonance imaging (MRI) have shown superiority over radiographs in diagnostic evaluation of bone deformities. The inaccuracy due to femoral malposition using CT and MRI has been investigated and statistically quantified .…”

“…The inaccuracy due to femoral malposition using CT and MRI has been investigated and statistically quantified . CT and MRI have been used to assess femoral conformational deformities, detect geometry and joint changes mediated by surgical treatment, as well as quantify and monitor joint disease for early diagnosis of hip dysplasia . Although malpositioning can be effectively reduced using CT and MRI, these techniques allow improvement of femoral orientation and visualization of specific anatomic landmarks since the measurement of femoral angles and axes is still achieved with 2‐dimensional (2D) imaging.…”

“…Although malpositioning can be effectively reduced using CT and MRI, these techniques allow improvement of femoral orientation and visualization of specific anatomic landmarks since the measurement of femoral angles and axes is still achieved with 2‐dimensional (2D) imaging. Thus, the preferred assessment of femoral morphometric parameters is still unclear …”

“…Efforts to develop consistent and standardized imaging protocols have improved the accuracy of assessment and quantification of femoral deformities . Human medical research has focused on developing imaging modalities that generate precise morphometric analyses of bone surfaces through the reconstruction of 3D geometric models.…”
