What is Dexa?
DEXA (DUALENERGY XRAY ABSORPTIOMETRY),
SOMETIMES CALLED DXA, IS AN ADVANCED IMAGING
TECHNOLOGY THAT USES TWO VERY LOWDOSE XRAY
BEAMS TO MEASURE THE COMPOSITION OF YOUR
BODYWITH EXCEPTIONAL ACCURACY.
BY DIFFERENTIATING BETWEEN BONE, MUSCLE, AND FAT TISSUE, IT PROVIDES TWO VITAL TYPES OF INFORMATION:
BONE MINERAL DENSITY (BMD)
FOR DIAGNOSING OSTEOPOROSIS AND FRACTURE RISK.
DEXA IS WIDELY REGARDED AS THE GOLD STANDARD FOR BOTH BONE DENSITY TESTING AND PRECISE MEASUREMENT OF BODY COMPOSITION.
DETAILED BODY COMPOSITION ANALYSIS
INCLUDING LEAN MUSCLE MASS, FAT MASS, AND VISCERAL FAT DISTRIBUTION.

How Dexa Works
DURING A DEXA SCAN, YOU LIE ON A FLAT, OPEN TABLE WHILE A SCANNING ARM PASSES SLOWLY OVER YOUR BODY.
The machine emits two different lowenergy xray beams. Because bone, fat, and muscle absorb these beams at different rates, the scanner can separate and quantify each tissue type with high precision.
BODY
COMPOSITION
BEYOND BONE HEALTH, DEXA PROVIDES A DETAILED BREAKDOWN OF YOUR BODY COMPOSITION:
TOTAL BODY FAT PERCENTAGE AND FAT DISTRIBUTION.
VISCERAL FAT LEVELS, WHICH ARE LINKED TO CARDIOMETABOLIC RISK.
LEAN MUSCLE MASS IN DIFFERENT REGIONS, MAKING IT ESPECIALLY USEFUL FOR ATHLETES, THOSE ON WEIGHT MANAGEMENT PROGRAMMES, AND ANYONE TRACKING MUSCLE GAIN OR FAT LOSS.
BONE OSTEOPEROSIS
DEXA BONE DENSITY SCANS ARE THE STANDARD CLINICAL TOOL FOR:
DIAGNOSING OSTEOPENIA & OSTEOPOROSIS.
ASSESSING FRACTURE RISK.
MONITORING CHANGES IN BONE STRENGTH OVER TIME OR DURING TREATMENT.
Is Dexa Safe?
THE RADIATION DOSE FROM A DEXA SCAN IS EXTREMELY LOW.
To put it into context, the amount of radiation you receive from a wholebody dexa scan is roughly equal to one day of natural background radiation that we are all exposed to in the environment. This makes the test safe, noninvasive, and suitable for ongoing monitoring over time.
WHY CHOOSE DEXA?
GOLDSTANDARD ACCURACY FOR BOTH BONE AND BODY COMPOSITION ANALYSIS.
LOW RADIATION DOSE – SAFE, FAST, AND NONINVASIVE.
ACTIONABLE DATA THAT SUPPORTS BOTH MEDICAL DECISIONMAKING AND PERSONAL HEALTH GOALS.
At DEXA London, we combine cutting edge scanning technology with expert interpretation to deliver clear, clinically reliable insights—whether you are concerned about bone health, managing weight, improving performance, or simply gaining a deeper understanding of your body.
