Use of Equipment For Measuring Bone Density
Bone density describes a medical term which refers to the amount of matter per square centimeter of bones. It also explains the measure of mass of bones in relation to their volume. This helps in determining the risk of osteoporosis. Different bone density measurement tests utilize a variety of bone density measurement equipment.
Bone density can be measured through a process known as densitometry. The procedure is performed in nuclear medicine or radiology departments of clinics and hospitals. Moreover, the measurement is non-invasive and painless. It also involves minimum exposure to radiations. Majority of measurements are made over the upper region of hip and over lumbar spine. In case, if both lumbar spine and hip cannot be scanned, then the forearm is scanned. The average bone density is approximately 1500 kg/m3.
The densitometer is a bone density measurement equipment that measures bone density at different sites within the body by utilizing a small quantity of radiation. There are two types of densitometers, extremity bone densitometers and whole body densitometers. While conducting a bone density test, the patient lies on a whole body bone densitometer that bears resemblance to a large padded examination table.
A bone densitometer is capable of detecting osteoporosis before a fracture takes place. This also determines the possibility of occurrence of fracture and determines the rate of bone loss. The test is capable of monitoring the effect of treatment if conducted after a period of one year.
With an increase in age, the bone density tends to decrease. However, this can be prevented by regular exercises.
