A scanner used to measure bone density using dual energy X-ray absorptiometry. Bone density, or bone mineral density, is the amount of bone mineral in bone tissue.The concept is of mass of mineral per volume of bone (relating to density in the physics sense), although clinically it is measured by proxy according to optical density per square centimetre of bone surface upon imaging.

High bone density, Acro-osteolysis and obtuse mandibular angle are the characteristic radiological findings of this disorder. [10] Pycnodysostosis also causes problems that may become evident with time. Aside from the broken bones, the distal phalanges and the collar bone can undergo slow progressive deterioration.
Bone mineral density (BMD) is a measure commonly used to quantify bone health. A lower BMD value indicates an increased risk of an osteoporosis or a fracture. [13] There is a large range of factors influencing BMD. Protein consumption has shown to be beneficial for bone density by providing amino acid substrates necessary for bone matrix formation.
Osteosclerosis is a disorder characterized by abnormal hardening of bone and an elevation in bone density. It may predominantly affect the medullary portion and/or cortex of bone. Plain radiographs are a valuable tool for detecting and classifying osteosclerotic disorders. [1] [2] It can manifest in localized or generalized osteosclerosis.
Other symptoms include thickening of the bone structure and accumulation of bone tissue, which both contribute to impaired joint mobility. Ligaments and cartilage can become ossified. [3] Most patients with skeletal fluorosis show side effects from the high fluoride dose such as ruptures of the stomach lining and nausea. [4]
High intensity and high impact training is shown to be extremely beneficial in improving bone health and the most effective in improving, maintaining, bone density in the lower spine and femur. Although these types of exercises are safe for postmenopausal women, there still may be a need for supervision and precautionary measures.
Gorham's disease (pronounced GOR-amz), also known as Gorham vanishing bone disease and phantom bone disease, [1] is a very rare skeletal condition of unknown cause.It is characterized by the uncontrolled proliferation of distended, thin-walled vascular or lymphatic channels within bone, which leads to resorption and replacement of bone with angiomas and/or fibrosis.
In primary hyperparathyroidism, about 75% of people are "asymptomatic". [1] While most primary patients are asymptomatic at the time of diagnosis, 'asymptomatic' is poorly defined and represents only those without "obvious clinical sequelae" such as kidney stones, bone disease, or hypercalcemic crisis.
