Bone Density Scan
Bone density generally refers to the strength of a bone and its ability to bear weight. Doing a bone density scan therefore measures a bone’s strength, its ability to bear weight, and its risk of fracture. The most common and accurate way to measure bone density is to use a Dual-Energy X-ray Absorptiometry (DEXA) scan. (Medlineplus, 2014). Before the use of DEXA was introduced, osteoporosis could be determined only when a patient broke a bone, and by then, the bone may have become very weak. With a bone density scan however, it can be determined if a patient is at risk of bone fracture, or at risk of osteoporosis. The bone density scan is done with Dual Energy X-ray Absorptiometry (DEXA) equipment. The DEXA technology became available for clinical use in 1987, but before then, there were the Single Photon Absorptiometry (SPA), and Dual Photon Absorptiometry (DPA), both of which are no longer in use. (Dasher, Newton, & Lenchik, 2010). The bone density scan is usually done on the following patients:

• Post menopausal women not taking estrogen.
• Patients with personal or maternal history of hip fracture or smoking.
• Post menopausal women who are tall (over 5ft 7inches), or thin (less than 125lbs).
• Men with clinical conditions associated with bone loss.
(, 2013).
The DXA Scanner
Driver, (2013), described the DEXA scanner as a machine that produces two x-ray beams of high and low energy levels. Much like fluoroscopy, the x-ray from the DEXA scanner comes from underneath the patient, and the scanner has a very low x-ray dose. Earlier versions of the DEXA scanner emitted radiation which required up to five minutes to scan an area of interest, but the more advanced machines can take as ...

Osteoporosis : A Disease Of The Bone Essay

- Osteoporosis Osteoporosis is a disease of the bone. The bones become weak and brittle and are prone to fractures. A person with osteoporosis can fracture a bone just by hitting a table or turning while in bed. Most people with osteoporosis keep on getting fractures because the weight of the body cannot be supported by the bone and normal body movements, including walking, will strain the bone. This condition arises when the rate of bone growth cannot keep pace with bone loss. Osteoporosis can affect any bone including the hip, wrist or spine....   [tags: Osteoporosis, Bone, Bone density, Bone fracture]

- There are many different diseases that can affect our skeletal system and Osteoporosis is one of them. Osteoporosis lessens bone strength and bone density (amount of bone mineral in bone tissue), which will lead to fragile bones. It mainly affect the hips, ribs, spine, and wrists. Male or female, at any age, can get this but it is mostly occurs in older women (Team, 2016). Osteoporosis is very common, there are more than 3 million cases a year.

Osteoporosis Essay

- Osteoporosis is defined as a medical condition in which the bones become brittle and fragile from loss of tissue. One could use the word osteopenia in the place of osteoporosis; however, not every person diagnosed with osteopenia will develop osteoporosis. Osteopenia is a condition having to do with reduced bone mass due to the decrease in the rate of osteoid synthesis (organic material of bone) to the level insufficient to compensate normal bone declination. Basically, osteopenia is the decreased calcification or density of bone....   [tags: Osteoporosis, Bone]

Osteoporosis Essay

- Osteoporosis is when the bone weakens and becomes fragile. Bones become really delicate and any small fall can cause a bone fractures. The most common bone fractures happen in the hip, spine or wrist. Bones are made up of two types of living tissue, cortical bone, and trabecular bone. Cortical bone is also known as compact bone, is the hard part of the bone that is the exterior of the bone and acts as a shell for the bone. The trabecular bone is also known as the spongy bone and is honeycomb-like in the inside of long bones and in between the vertebrae....   [tags: Osteoporosis, Bone, Skeletal system, Vitamin D]
