How is your Bone Density Measured?
In medical terminology, bone density describes the quantity of matter that is present every square centimeter of bones. This also describes the measurement of mass of bones with respect to the volume. It helps in calculating the risk of osteoporosis. Every bone density measurement test utilizes a different bone density machine. Besides this, bone density is also measured with the help of a procedure called densitometry. Generally, the process is conducted in radiology or nuclear medicine departments of hospitals and clinics. In addition, the measurement is painless and non-invasive. Moreover, the measurement involves minimal exposure to the radiations. Most of the measurements are performed over the upper area of hip as well as over the lumbar spine. If both hip and lumbar spine as well as the hip of a patient cannot get scanned, then the forearm of the person gets scanned. On an average, the bone density of an individual is about 1500 kg/m3.
The densitometer is a bone density machine utilized for measurement of bone density at various locations in our body through the use of a small quantity of radiation. In general densitometers are of two types, whole body densitometers and extremity bone densitometers. During a bone density test, the individual lies over a whole body bone densitometer which resembles a large-padded examination table.
A bone densitometer can detect osteoporosis prior to the occurrence of a fracture. Moreover, it helps in determining the possibility of fracture and decides the rate of bone loss. In addition, the test monitors the effect of treatment when performed on an annual basis.
