DUAL X-RAY ABSORPTIOMETRY

DUAL X-RAY ABSORPTIOMETRY

Overview and Facts

Dual X-ray absorptiometry test measures bone density by passing through x-rays with two different energy levels through the bone. It is utilized to analyze osteoporosis.

The dual x ray radiates with various energy levels, and is focused on the patient’s bones. When delicate tissue assimilation lessens, the bone mineral thickness can be resolved from the retention of each pillar by bone. In dual x-ray absorptiometry, it generally utilized and most closely examined bone thickness estimation innovation.

It is commonly used to diagnose and follow-up osteoporosis, as differentiated to the atomic bone output, which is sensitive to certain metabolic disorders in which bones are endeavoring to recuperate from infection, cracks, or tumors.

Types and Symptoms

SYMPTOMS

Dual X-ray absorptiometry is regularly used to diagnose osteoporosis, a condition that frequently affects women after menopause; however, it may likewise be found in men and seldom in kids. Osteoporosis includes a slow bone deficiency, just as underlying changes, making the bones more slender, more delicate, and bound to break.

DXA is also helpful in following the impacts of osteoporosis treatment and different conditions that cause bone loss.

The test can likewise evaluate a person’s risk for fractures in bones. The danger of bone fracture is influenced by age, body weight, history of earlier fractures, family background of osteoporosis, and lifestyle habits, such as cigarette smoking and uncontrolled alcohol use. These components are contemplated when choosing if a patient requires treatment.

Diagnosis & Medications

DIAGNOSIS

Dual x rays are suggested in:

  • Women in the post-menopausal stage
  • An individual with a personal or maternal history of hip fracture 
  • Smoking
  • Male with clinical conditions related to bone loss
  • Use pharmaceutical drugs that cause bone breakage
  • A person with type 1 diabetes, kidney disease, liver disease, or genetic osteoporosis
  • Experiencing high collagen production in urine
  • Having thyroid condition, and parathyroid conditions

After the tests, you’ll get a T-score. The lower your score, the more fragile your bones are:

  • -1.0 or above = normal
  • between -1.0 and -2.5 = low, or osteopenia
  • -2.5 or lower = osteoporosis

In some cases, specialists will give you another DXA examine result, a Z score. It gives an idea about your bone thickness score related to that of an individual of your equivalent age and body size
