What equipment is needed for DEXA?
You will be asked to lie on a special DEXA x-ray table. The technologist will help position your correctly and use positioning devices such as foam blocks to help hold the desired position. As the arm of the DEXA machine passes over the body, IT uses two different x-ray beams.
What machine is used for a DEXA scan?
A DXA scanner is a machine that produces two X-ray beams. One is high energy and the other is low energy. The machine measures the amount of X-rays that pass through the bone from each beam.
How does a DEXA unit operate?
The DXA machine sends a thin, invisible beam of low-dose x-rays with two distinct energy peaks through the bones being examined. One peak is absorbed mainly by soft tissue and the other by bone. The soft tissue amount can be subtracted from the total and what remains is a patient’s bone mineral density.
What is the DEXA used for?
Bone density scans, also known as DEXA scans, help to work out your risk of breaking a bone. They’re often used to help diagnose bone-related health problems, such as osteoporosis, or to assess the risk of getting them.
What is a central DXA machine?
Central DXA devices are large machines that can measure bone density in the centre of your skeleton, such as your hip and spine. Peripheral DXA devices are smaller, portable machines that are used to measure bone density on the periphery of your skeleton, such as your wrist, heel or finger.
What is the difference between a DEXA scan and a bone density test?
A bone-density test is a way to measure the strength of your bones. The test, called a DEXA scan, is a kind of X-ray. Many people get a bone-density test every few years. The main reason to have the test is to find and treat serious bone loss, called osteoporosis, and prevent fractures and disability.
What is the cost of BMD test?
A Dexa Scan is a unique type of X-ray that measures Bone Mineral Density ( BMD). Dexa Scan cost range from Rs 1500 to Rs 6000 depending on lab, location and body part. Full form of DEXA is Dual Energy X-Ray Absorptiometry.
How many MSV is a DEXA scan?
One sievert of radiation causes immediate sickness. One sievert is a very large dose of radiation, and most radiation doses are much, much smaller. Getting a DEXA scan is very safe, even if you scan 3-4 times a year….Source.

What does dexamethasone do to the brain?
Dexamethasone and Brain Tumors “Dexamethasone is really the only steroid that can effectively decrease inflammatory reactions in the brain to help our patients,” he said. Some patients receive dexamethasone to prevent inflammation in the brain and remain on the medicine indefinitely.
Does dexamethasone give you energy?
Dexamethasone can give people an increase in energy. They may also develop insomnia, or difficulty sleeping. Taking the medication in the morning may help to prevent this.
What does a DEXA scan involve?
During the scan, a large scanning arm will be passed over your body to measure bone density in the centre of the skeleton. As the scanning arm is moved slowly over your body, a narrow beam of low-dose X-rays will be passed through the part of your body being examined.
What are the different types of DEXA equipment?
There are two types of DEXA equipment: a central device and a peripheral device. Central DEXA devices measure bone density in the hip and spine and are usually located in hospitals and medical offices. Central devices have a large, flat table and an “arm” suspended overhead.
Where are the Central devices used for DXA?
Most of the devices used for DXA are central devices, which are used to measure bone density in the hip and spine. They are usually located in hospitals and medical offices. Central devices have a large, flat table and an “arm” suspended overhead.
What does DEXA stand for in medical terms?
What is a peripheral Bone Density Scan (DEXA)? Bone density scanning, also called dual-energy x-ray absorptiometry (DXA or DEXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. Peripheral DEXA devices, measure the wrist and forearm, are used for screening purposes.
Which is more accurate peripheral DEXA or central DEXA?
This device has a large, flat table and an arm suspended Overhead. Peripheral DEXA Device – These scanners are small portable devices which measure BMD in the Heel or Forearm. This is used to estimate overall fracture risk, but they are less accurate compared to central DEXA.
