Experimental investigation of bone mineral density in Thoroughbreds using quantitative computed tomography

Bone Mineral Density Changes in Growing and Training Thoroughbreds

Bone mineral density contributes to bone strength, and can be measured accurately in the distal limb of growing or training young horses. In training horses, changes occur within less than 3 months, and consist of trabecular thickening in the subchondral area and specific areas of the body of the epiphysis of longbones and the cuboidal bones. In the growing horse, variation in mineral density b...

Prediction of Human Vertebral Compressive Strength Using Quantitative Computed Tomography Based Nonlinear Finite Element Method

Introduction: Because of the importance of vertebral compressive fracture (VCF) role in increasing the patients’ death rate and reducing their quality of life, many studies have been conducted for a noninvasive prediction of vertebral compressive strength based on bone mineral density (BMD) determination and recently finite element analysis. In this study, QCT-voxel based nonlinear finite eleme...

Evaluation of Bone Mineral Density of the Necrotic Area in Osteonecrosis of the Femoral Head Using Quantitative Computed Tomography

Assessment of bone fragility with clinical imaging modalities.

INTRODUCTION Osteoporotic fractures are a vital public health concern and have created a great economic burden to our society. Therefore, early diagnosis of patients with high risk of osteoporotic fractures is essential. The current gold standard for assessment of fracture risk is the measurement of bone mineral density using dual-energy X-ray absorptiometry. However, such techniques are not ve...

Effects of unilateral sciatic neurectomy on growing rat femur as assessed by peripheral quantitative computed tomography, Fourier transform infrared spectroscopy and bending test.

We studied the effects of unilateral sciatic neurectomy (USN) on the development of the femoral shaft in the 30 growing Wistar-derived rats aged 5 weeks. Rats were allocated to three groups. One of these was immediately used for measurements, and the remaining 2 groups underwent USN of internal control. Specimens obtained from each group were divided into 2 subgroups: left femurs of each group ...
