What is a DEXA Scan?
A DEXA scan is a quick, low dose X-ray that measures bone mineral density and body composition. It is the clinical gold standard for both. At DEXA London, scans are carried out by trained radiographers at our CQC-registered clinic at 86 Harley Street in Marylebone, with no GP referral needed and results returned the same day.
BY DIFFERENTIATING BETWEEN BONE, MUSCLE AND FAT TISSUE, IT PROVIDES VITAL INFORMATION
BONE MINERAL DENSITY
DIAGNOSE OSTEOPOROSIS AND PREDICT FRACTURE RISK.

How Dexa Works
DURING A DEXA SCAN, YOU LIE ON A FLAT, OPEN TABLE WHILE A SCANNING ARM PASSES OVER YOUR BODY.
The machine emits two different low-energy X-ray 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
FULL BODY SCAN FOR A DETAILED BREAKDOWN:
BODY FAT PERCENTAGE AND FAT DISTRIBUTION.
VISCERAL FAT LEVELS LINKED TO METABOLIC RISK.
MUSCLE MASS IN DIFFERENT REGIONS, USEFUL FOR THOSE ON WEIGHT LOSS PROGRAMMES OR ANYONE TRACKING MUSCLE GAIN & FAT LOSS.
BONE DENSITY
BONE DENSITY SCANS ARE THE STANDARD ASSESSMENT FOR:
DIAGNOSING OSTEOPENIA & OSTEOPOROSIS.
ASSESSING FRACTURE RISK.
MONITORING BONE STRENGTH OVER TIME OR DURING TREATMENT.
Is Dexa Safe?
THE RADIATION DOSE FROM A DEXA SCAN IS EXTREMELY LOW.
The amount of radiation you receive from a full body DEXA scan is equal to one day of background radiation that we are exposed to in the environment. This makes the test safe and suitable for ongoing monitoring over time.
