Focal vertebral bone density changes were assessed in vertebral computed tomography (CT) images obtained from clinically healthy dogs without diseases that affect bone density. The number, location, and density of lesions were determined. A total of 429 vertebral CT images from 20 dogs were reviewed, and 99 focal vertebral changes were identified in 14 dogs. Focal vertebral bone density changes...

28 Purpose: This study was carried out to analyze volumes and localization of vertebral 29 hemangiomas in T12-L5 levels on MRI in patients with low back pain. 30 Methods: Thoraco-lumbar MR images were examined retrospectively in a total of 150 31 patients. Hemangiomas observed in vertebral bodies on sagittal vertebral sections were 32 assessed and data were evaluated to get ratios regarding sex...

STUDY DESIGN Ex vivo biomechanical study using osteoporotic cadaveric vertebral bodies. OBJECTIVE To determine if fracture reduction could be achieved by the inflatable bone tamp (tamp) in vertebral bodies under simulated physiologic loads. SUMMARY OF BACKGROUND DATA Previous ex vivo biomechanical studies showed that kyphoplasty restored vertebral body height with vertebral body endplates u...

BACKGROUND AND PURPOSE MR imaging has been used extensively for identification and determination of chronicity of VCF. A major emphasis is placed on identification of edema or fluid clefts within the vertebral body. Little attention is given to other spinal structures such as vertebral endplate, intervertebral disk, posterior elements, and facet joints, spinal ligaments, and paraspinal musculat...

carotid artery counterpart. Rocha-Singh insightfully attributed this to the nonspecific symptoms associated with posterior cerebral ischemia, difficulties imaging proximal vertebral artery stenosis with ultrasound, and the absence of a standard surgical therapy for vertebral artery disease.2 The relationship between vertebral artery insufficiency and posterior circulation ischemia is now becomi...

Introduction: to investigate prevalence and underlying risk factors for vertebral fractures in male geriatric outpatients on radiographs of the thoracolumbar spine. Methods: 176 men, mean age 80 years, first‐time visiting a geriatric day hospital, underwent a comprehensive geriatric assessment, routine laboratory investigation and lateral X‐rays of the chest and lumbar spine. The presence of ve...

Vertebral hemangioma is the most common spinal axis tumor. This rare presentation of a vertebral hemangioma extended contiguously from one cervical vertebra to another, encasing the vertebral artery, and thereby mimicking other tumors of the spine. We discuss the differential diagnosis of bridging vertebral masses.

OBJECTIVES To determine the prevalence of vertebral fracture in postmenopausal women with steroid treated rheumatoid arthritis (RA), and whether the risk of vertebral fracture could be predicted from measurements of bone mineral density (BMD). METHODS Vertebral deformities were defined from spine radiographs in 76 postmenopausal women with steroid treated RA (aged 50-79 years) and 347 age mat...

In the United States, there are 1.5 million fractures attributed to osteoporosis every year. Among them are 700,000 vertebral fractures.1 Vertebral compression fractures have a greater than 15% reduction in vertebral body height and are most often observed in the thoracolumbar transition zone.2 Patients typically present with back pain and get diagnosed with a vertebral fracture following X-ray...
