A complete comparison — accuracy, cost, radiation, speed, and when each test makes sense.
| Factor | InBody (DSM-BIA) | DEXA Scan |
|---|---|---|
| Technology | Direct Segmental Multi-frequency BIA — 8-electrode, 3 frequencies | Dual-energy X-ray Absorptiometry |
| Scan Time | 60 seconds | 20–30 minutes |
| Radiation | None — completely safe for frequent use | Low-dose X-ray — accumulates with repeated scans |
| Accuracy | 98% correlation with DEXA (published studies) | Gold standard reference method |
| Body Fat % | Yes — segmental and whole-body | Yes — whole-body |
| Lean Muscle Mass | Yes — by segment (arms, legs, trunk separately) | Yes — regional, less granular segmentation |
| Visceral Fat | Yes — visceral fat level and area | No — DEXA does not measure visceral fat |
| Bone Mineral Density | No — InBody does not measure bone density | Yes — gold standard for bone density |
| ECW/TBW Fluid Ratio | Yes — oedema and fluid imbalance detection | No |
| Basal Metabolic Rate | Yes — estimated from lean mass | No |
| Portability | Portable — can be installed anywhere | Large fixed machine — requires imaging centre |
| Cost per Scan (India) | ₹500 – ₹2,000 at scan centres | ₹2,000 – ₹6,000 at hospitals |
| Frequency of Use | Safe for weekly or monthly tracking | Limited due to radiation and cost |
| Availability in India | Hundreds of locations — gyms, hospitals, wellness studios | Limited to major hospitals and imaging centres |
| Safe for Children | Yes — no radiation, all ages | Restricted use due to radiation |
| Clinical Validation | FDA-cleared, CE-marked, used at AIIMS & leading hospitals | Widely validated, gold standard for bone density |
Note: For body composition monitoring — muscle mass, body fat, visceral fat, fluid balance — InBody is the clinically preferred tool at most leading Indian hospitals. DEXA is irreplaceable only when bone mineral density is the specific clinical question.
Standard single-frequency BIA devices (bathroom scales, basic monitors) have significant accuracy limitations. InBody uses a fundamentally different approach: Direct Segmental Multi-frequency Bioelectrical Impedance Analysis (DSM-BIA).
InBody passes a safe, imperceptible electrical current through each body segment — right arm, left arm, trunk, right leg, left leg — individually, at multiple frequencies. This segmental, multi-frequency approach eliminates the estimation errors that affect cheaper BIA devices.
Published validation studies across multiple countries and clinical populations consistently show InBody body fat and muscle mass values within the margin of error of DEXA measurements.
InBody achieves 98% correlation with DEXA in published peer-reviewed clinical validation studies. For body fat percentage and lean muscle mass, InBody results are clinically comparable to DEXA. DEXA remains the gold standard specifically for bone mineral density — InBody does not measure bone density. For routine body composition tracking, InBody is the preferred choice in most clinical and fitness settings due to speed, safety, and cost.
InBody uses DSM-BIA — a 60-second scan with zero radiation, portable, available at gyms and clinics. DEXA uses X-ray technology, takes 20–30 minutes, requires a hospital or imaging centre, and involves low-dose radiation. InBody additionally provides outputs DEXA does not: segmental muscle by limb, visceral fat level, and ECW/TBW fluid ratio. DEXA’s unique value is bone mineral density measurement, which InBody cannot perform.
No. InBody uses a safe, low-level electrical current — zero radiation. This makes InBody safe for frequent monitoring and suitable for all ages including children and elderly. DEXA uses low-dose X-ray radiation which, while small per scan, accumulates with repeated use.
InBody scan centres are available across Mumbai, Delhi, Bangalore, Chennai, Hyderabad and most major Indian cities — at gyms, hospitals, and wellness centres. Call InBody India at +91 80975 11852 or WhatsApp to find the nearest verified scan centre. An InBody scan typically costs ₹500–2,000, compared to ₹2,000–6,000 for a DEXA scan.
For body composition monitoring — tracking muscle mass, body fat, visceral fat, and fluid balance — InBody can replace DEXA in most clinical workflows. Leading hospitals across India use InBody in bariatric, oncology, nephrology, and sports medicine departments for routine body composition assessment. Where bone mineral density is specifically required (osteoporosis, fracture risk), DEXA remains necessary.
An InBody scan typically costs ₹500–2,000. A DEXA scan typically costs ₹2,000–6,000 depending on city and facility. For hospitals and gyms purchasing InBody equipment, the per-scan cost in a high-volume setting drops well below ₹100.
InBody analyzers are used by leading multi-specialty hospitals, AIIMS-affiliated programs, bariatric surgery centres, oncology departments, and sports medicine institutes across India. Contact us at +91 80975 11852 for a clinical demonstration or to find a hospital near you that uses InBody.
