Dual năng lượng hấp thụ tia X (DEXA)

DEXA is also known as bone densitometry.
What is a bone density scan?

Bone densitometry uses low-dose high energy x-rays to evaluate the density or thickness of bone. The patient's bone density results are compared to an international standard. Based on this comparison, your doctor can assess your risk of developing fractures, such as the spine and hips, and recommended therapy to counter or reverse the process of bone loss.


What happens during the exam?

A bone densitometry study exposes the patient to less radiation than that of a typical x-ray study. The patient lies atop an examination table. The examination itself lasts less than 20 minutes.

What is Osteoporosis?

Osteoporosis is a common disease in which bone tissue become thinned and fragile. If not prevented or if left untreated, osteoporosis can progress painlessly until a bone breaks. These broken bones, also known as fractures, occur typically in the hip, spine, and wrist. The best way to determine Bone Density & Fracture Risk is to have a DEXA scan that accurately measures your Bone Mineral Density (BMD). Diagnosis of osteoporosis can only be made by a physician through a bone density test. Osteoporosis can be diagnosed easily and treated successfully if caught early.

Is the DEXA exam safe?

In most cases, your radiation exposure will be a fraction of what you would receive from a standard chest x-ray. As with any medical procedure, be sure to inform your physician if you are pregnant.
