Scale Your Bone Density By Sophisticated Technologies

Bone density (also called bone mineral density) refers to a medical term that is used to measures the amount of matter per cubic centimeter of bones. In radiology, it is measured by a particular procedure called densitometer. Such type of scaling is painless and noninvasive that takes the help of minimal radiation exposure. There are basically three types of parameters to measure bone density, such as g/m2, ‘Z-score’ and ‘T-score’. The z-score is the standard deviation above/below the mean of the patient’s sex and age. While the t-score refers to the standard deviation above/below the mean of the healthy person of the same age and sex.

Densitometry is used to diagnose osteoporosis- a serious disease in which bones become very fragile and settle at a high risk of fracture. With the passing of age, bones are tending to become fragile due to loss of calcium and minerals and lose their normal density, this stage is called ‘Osteopenia’. Under the bone density test we calculate the density of these minerals and calcium. The measurement process can be performed by various methods, such as computed tomography (CT) scan, x-ray or ultrasound.

Ultrasound is a basic bone density test that is performed to diagnose the primary bone related problems. The Duel energy X-ray absorptiometry or DEXA test is a successful method of bone density testing that uses two different x-ray beams to view the density. This type of test can scale as less as 2% loss of bone density, per year. Though it is a fast but costlier than the ultrasound. The Single Energy X-ray absorptiometry (SEXA) can be used for the bones of forearms and heel.

Another important test is Peripheral dual energy x-ray absorptiometry (P-DEXA test). It is used to measure the density of the bones of arms, wrists and legs. There are two more tests used to calculate bone density, such as Dual photon absorptiometry test (DPA test) and Quantitative computer tomography scan (Q-CT scan). These are also performed in the medical treatment by the physicians.
