Services - Bone Densitometry
Bone Density Scanning, also called dual-energy x-ray absorptiometry (DEXA) or bone densitometry, is an advanced form of X-Ray technology that is used to measure bone loss. DEXA is today's established standard for measuring bone mineral density (BMD).
Prodigy: GE is the first system designed to look beyond bone mineral density to become the most complete bone assessment tool ever devised. Prodigy’s improved technology detects subtle bone changes in a variety of clinical conditions and provides Advanced Hip Analysis and Lateral Vertebral Assessment.
Utilizing Direct-digital detector technology, Prodigy delivers rapid scans, near radiographic imaging and dose efficiency three to five times better than the existing fan beam systems. And its comprehensive capabilities cover a complete range of applications. Prodigy’s unique software optimizes productivity with automation breakthroughs that save time and ensure consistent results. And paperless digital reporting makes densitometry results accessible quickly and easily. Looking ahead, Prodigy links you to the future with extensive options for connecting with local facility networks and the Internet, for instant integration of bone assessment results across your entire healthcare system.
Its narrow-angle fan beam makes multiple passes across the patient to acquire multiple images, with each image overlapping the previous one.
The exact depth of the bone is determined accurately in every patient, ensuring precise, reliable, consistent measurement of area, bone mineral content and geometry such as hip axis length (HAL).
The GE Lunar Prodigy delivers these remarkable analytical capabilities.
Advanced Hip Analysis
The Prodigy provides the first major advances in femoral densitometry analysis since the introduction of DXA system software in 1987. These advances are included in the new Advanced Hip Analysis software, available exclusively on the Prodigy. Advanced Hip Analysis includes all the standard femoral regions of interest that have been previously available, but now includes the addition of other key measurements and assessments:
- Hip Axis Length (HAL) has been demonstrated in prospective studies as an effective adjunct to femur bone density in predicting fracture risk.
- DualFemur™ Assessment identifies the weakest femur while improving precision over single-femur measurements.
- New diagnostic regions of interest such as the upper neck can now be accurately assessed.
- Femur Strength Index : A unique Index combining geometrical parameters and BMD for a better assessment.
Lateral Vertebral Assessment-quantified
Prodigy’s Lateral Vertebral Assessmentquantified (LVAq) improves fracture risk assessment by identifying and quantifying existing vertebral fractures – which at least double future fracture risk
Customized regions of interest of any shape and size can be quickly defined for greater utilization, and customized enCORE analysis assures precise results while expanding your clinical and research applications.
Total Body Assessment
The ultimate in skeletal assessment, the Total Body exam provides both bone density and body compositon (i.e., % fat) results. With an FDA-approved, gender-matched database, total body results expand the utility beyond osteoporosis management where the combined results are used in a variety of secondary conditions, or when spine/hip measurements are compromised
Revolutionary enCORE software optimizes productivity.
One-step AutoAnalysis delivers fast, precise, consistent results.
OneVision scanning and reporting saves time and costs.
Dual-Energy X-Ray Absorptiometry (DEXA) is the most accurate and advanced test available for measuring bone mass with excellent resolution and reproducible precision. Mineral radiation (less than 1/20 of a chest x-ray) is used to determine the bone density of the spine, hip or wrist. A DEXA test is more sensitive than ordinary x-rays, more accurate than radiograms (radiographic absorptiometry) and can diagnose bone loss at an earlier stage. Safe and painless, the 10 minute DEXA scan is the most reliable test to determine even the earliest stages of bone loss associated with osteoporosis.
What is Osteoporosis?
Osteoporosis literally means ‘porous bones’. It is a disease where the bones in the body become weak and brittle, so much so that they fracture even due to mils stress like bending over, cleaning and coughing.
Osteoporosis affects over 6.1 crore Indians- 1 out of 8 men and 1 out of 3 women suffer from osteoporosis, making India one of the largest affected countries in the world.
How does Osteoporosis occur?
The strength of bones depends on the amount of calcium, phosphorous and other minerals that are present in them. Osteoporosis silently depletes the bones of calcium, making them weak and prone to fractures. These fractures occur mostly in the spine, hips and wrists.
Osteoporosis can occur due to several reasons. At menopause, the rate of bone loss in women increases to about 1-3%, thereby increasing their risk of osteoporosis. Bone loss also accelerates in men over 65 years of age. Osteoporosis can also be caused due to endochrinal disorders or from excessive use of certain drugs.
How Osteoporosis can affect your life?
Osteoporosis can leave a person severely incapacitated. People suffering from osteoporosis cannot move freely and experience difficulty in performing routine activities like household cleaning, shopping and travelling. In many cases, the affected person cannot look after oneself and may even need to be admitted in a hospital.
What are the symptoms of Osteoporosis?
There are no symptoms or pain during the early stage of osteoporosis. Once the bones are weakened, the common symptoms include.
How can Osteoporosis be diagnosed?
Early detection is important in order to slow down or prevent osteoporosis. Considering your risk factors, your doctor may recommend a Bone Densitometry (BMD) Test to determine the strength of your bones. In case you are diagnosed with osteoporosis, your doctor will prescribe treatment program that is suited for you.
Q. What happens during the scan?
There is no special preparation required for the scan. All it involves is the lying on a table, breathing normally. No intravenous injections or oral medication. The intensity of radiation is extremely low. The whole procedure takes about 10 minutes.
Q. Why Physicians Request a DEXA Exam?
- To determine your actual bone density and fracture risk.
- To reveal early signs of bone loss with the fewest false positive or false negative results.
- To diagnose low bone mass that may signal the need for treatment.
