BMD WHOLE BODY

BMD Whole Body Overview

Introduction 

The Bone Mineral Density (BMD) Whole Body Scan is an advanced diagnostic test that measures the strength and density of bones throughout the body. This scan is typically used for the early diagnosis and treatment of osteoporosis, estimation of fracture risks, and monitoring in sequential evaluations.  

What is BMD Whole Body Scan? 

A BMD Whole Body Scan is a type of DEXA or DXA scan performed on patients with special needs. It makes use of dual-energy X-ray absorptiometry to measure a patient’s bone density throughout the entire body. This test is very useful in evaluating the overall condition of the skeleton and helps in the early identification of bone mineral deficiency and its related problems. 

Types of BMD Whole Body Scan 

• QCT (Quantitative Computed Tomography): Provides 3D analysis but sacrifices more radiation exposure. 
• Peripheral BMD Testing: Assess bone density in the limbs. 
• DEXA (Dual-Energy X-ray Absorptiometry): The industry standard and most accurate. Whole body bone density measurement is performed. 

List of Parameters Considered During The BMD Whole Body Scan

• Bone Mineral Density (BMD) values in grams per square centimetre 
• T-score: Comparison of bone density to a young, healthy adult 
• Z-score: Comparison of bone density to age-matched individuals 
• Fat and lean mass analysis (optional in some cases) 

Reasons for Taking BMD Whole Body Scan

• Evaluating overall bone health and fracture risk 
• Tracking the progression of osteoporosis 
• Assessing the impact of lifestyle, diet, or medication on bone density 
• Monitoring bone growth in children 

When and Who Needs BMD Whole Body Scan? 

Indications: 

• Osteoporosis patients (post-menopausal women, elderly people) 
• Patients with multiple fractures from minimal trauma 
• People on long-term steroid treatment 
• Potential athletes or individuals with eating disorders 
• Patients with metabolic or endocrine disorders and bone density changes 

Patient Demographics: 

• Post-menopausal women and elderly men. 
• Chronic illness patients impacting bone metabolism 
• Athletes and sedentary individuals with a poor diet 
• Growth deficient children 

Benefits of Taking the Test

• Non-invasive and quick procedure 
• Assesses the entire skeletal system 
• Essential for early detection of osteoporosis 
• Facilitates personalized treatment plans 

Illnessess Diagnosed with BMD Whole Body Scan

• Osteoporosis 
• Osteopenia (low bone mass) 
• Metabolic bone diseases 
• Fracture risk assessment 
• Deficiencies in nutrition impacting bone density 

Preparing for BMD Whole Body Scan

• No calcium supplements 24 hours before the test 
• Wear comfy, metal-free clothes 
• Notify the technician about recent contrast imaging 

Pre-requisites 

• No fasting required 
• No prior medication needed 

Best Time to Take BMD Whole Body Scan 

• Suggested every 1-2 years based on individual risk factors  
• Following the guidance of a physician  

Eligibility 

• Most people are eligible  
• Not applicable for pregnant women  

Steps in Completing BMD Entire Body Scan 

• Patient relaxes on a scanning table.  
• One DEXA scanner head rotates about a patient's body measuring about 200 different skeletal sites for density.  
• Procedure lasting between 20 to 30 minutes.  
• There is no need for injection of any radiographic contrast material.  

 Caution before taking the test 

• Pregnant individuals inform technician  
• Do not take calcium supplements prior to the test  
• Remove metallic ornaments which can block the scan view
