Lipoatrophia semicircularis, also known as semicircular lipoatrophy, [1] is a medical condition in humans, commonly known as ribbed thighs. It consists of a semicircular zone of atrophy of the subcutaneous fatty tissue located mostly on the front of the thighs. Skin and underlying muscles remains intact.
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.

Triple Test (for diagnosis of downs syndrome) Estimation of hcg, Estriol, and AFP: Down's Syndrome: Trotter's triad: Conductive deafness, Immobility of homolateral soft palate, Trigeminal neuralgia: Nasopharyngeal carcinoma: Unhappy Triad (Also known as O'Donoghue's triad or a blown knee) Injury to the ACL, MCL, and meniscus (either medial or ...
Bone densities are often given to patients as a T score or a Z score. A T score tells the patient what their bone mineral density is in comparison to a young adult of the same gender with peak bone mineral density. A normal T score is -1.0 and above, low bone density is between -1.0 and -2.5, and osteoporosis is -2.5 and lower.
DXA is only able to provide the areal bone mineral density. High-resolution peripheral quantitative computed tomography (HR-pQCT) is better than DXA at detecting bone microarchitecture, modeling whole-bone geometry using 3-dimensional information from scans. This method allows estimation of bone strength and other mechanical properties. [20]
The standard in bone mineral density scanning developed in the 1980s is called Dual X-ray Absorptiometry, known as DXA. The DXA technique uses two different x-ray energy levels to estimate bone density. DXA scans assume a constant relationship between the amounts of lean soft tissue and adipose tissue.
A long-term deficiency in vitamin D can lead to osteoporosis, a disease that causes bone density loss, which can increase the risk of fractures and broken bones. Osteoporosis itself can also cause ...
Osteogenic loading (OL) is a rehabilitative exercise method with the goal of improving bone density and preventing bone fracture. This may be seen as brief, intensive, resistance exercise for bone health. Osteogenic loading is an outpatient therapy that typically is used with ambulatory individuals who are able to engage in resistance exercise.
