a measurement of bone that denotes its ability to resist fracture.
The absorption of X-rays indicating the amount of mineral (mostly calcium) present in bone. In general, the more BMD, the stronger the bones.
a measure of the amount of bone and its mineral. There are several kinds but one called DXA uses very low doses of X-rays to make an accurate assessment. The two sites of BMD usually measured are in the lower spine (lumbar vertebrae numbers 1-4) and in the total hip. BMD should be repeated in the same season and no more frequently than every two years to obtain an accurate estimate of change. Standard deviations below average BMD for young women are called T Scores. A T Score lower than –2.5 is considered osteoporosis, and lower than –1.0 to -2.4 is called osteopenia.
a measure of the strength of bones, androgen deprivation can cause the loss of BMD resulting in osteoporosis, usually BMD is tested by dual-energy absorption x-ray ( DEXA) or quantitative CAT scan ( qCT) methods
a measurement of how thick and strong the bones in the body are.
The amount of mineralised bone tissue in a given area, usually calculated as grams per square centimetre
The quantity calculated by dividing the measured bone mineral content by the measured bone area in a densitometry study. The bone mineral density carries units of gram per square centimeter and is most often compared to reference population values.
This is a term used to describe the strength or density and reflects the amount of calcium present in bone. When the bone mineral density is low, osteopenia (moderate loss of bone density) or osteoporosis (severe loss of bone density) exists. There are no specific symptoms except for an increase in fractures.
A bone test shows how good your bones are compared with the average of a young group of women. It can spot osteoporosis before you have any signs of it.
an indication of bone strength measured in grams/square centimetre (gm/cm2)
BMD. A measure of the amount of calcium contained in a certain volume of bone. Calcium gives bones their strength and helps keep them from breaking. Bone density measurements may be used to diagnose osteoporosis, to see how well osteoporosis treatments are working, and to figure out how likely the bones are to break. Also called bone density and bone mass.
a term used in quantifying the mineralization of bone. The mineral component of bone consists largely of calcium and phosphorus. BMD is possitively associated with bone strength and resistance to fracture. BMD can be determined through a low radiation X-ray technique known as DEXA.
BDM, a measure of bone density, reflecting the amount of calcium in bones. The BDM test detects osteopenia (bone loss usually without symptoms) and osteoporosis (more severe bone loss which may cause symptoms). See also: Bone mass density, Osteopenia, Osteoporosis.
a marker for the strength of bones.
tests and the technology that they use is known as bone densitometry. These tests are safe, painless and accurately measure the density of your bones. A BMD test can tell you whether or not you have osteoporosis and how likely you are to develop it in the future, and can help you to make decisions that may prevent fractures or further bone loss.
A bone mineral density (BMD) test, also called a bone mass measurement, is used to measure bone density and determine fracture risk for osteoporosis. It may also be used to determine how effective an osteoporosis treatment is.
