Accurate, reproducible, and practical visceral fat quntifications on Lunar iDXA

To effectively assess obesity and metabolic diseases that affect millions of people, you need credible measurements of visceral fat—reproducible results from a validated method. Designed to do just that, CoreScan* gives you a fast and easy way to accurately quantify visceral fat.

The Lunar iDXA with the CoreScan application is the first and only system to quantify visceral fat by using low-dose, dual energy absorptiometry (DXA). It can help you predict patient risk, assess and manage treatment approaches, and add important contributions to the body of published research—all at a lower dose than conventional visceral fat measurement techniques.

The CoreScan application offers you the following benefits:


The CoreScan application features an exclusive algorithm that uses data from the Lunar iDXA body composition system—a validated DXA system you can trust.


Successful research and treatment begins with credible data: reproducible results from a validated method. CoreScan software sets a new standard for visceral fat quantification. It can help you predict cardio-metabolic risk, assess treatment approaches, and add important contributions to the body of published research. 


The CoreScan application puts accurate visceral fat quantification within reach—opening new possibilities for clinicians and researchers. It provides a fast, easy method, whether assessing individual patients or performing large clinical studies—and at a lower dose of radiation than conventional visceral fat-measuring methods.


CoreScan enhances your visceral fat assessments with the following technological advantages:


  • Excellent correlation with CT visceral-fat measurements, as shown in a study at Oregon Health & Science University1
  • Distinguishes between visceral and sub-cutaneous fat, using geometric calculations and attenuation measurements
  • Clear tissue characterization by Lunar iDXA provides the foundation for the CoreScan application to separate visceral fat from subcutaneous fat 


  • Standardized region of measurement determined by individual patient skeletal measurements
  • Assessment of the highly relevant android region (below the ribcage), where visceral fat deposits typically accumulate
  • Automatically defines the android region on each patient, avoiding variance between clinicians, machines, or research sites


  • Fully automated algorithm processing for consistent, fast, and accurate results
  • Data displayed in terms of volume and mass for easy comparison and study across patient populations
  • Intuitive software that analyzes and displays results in just a few clicks
  • Processes visceral fat results with total body composition analysis—avoiding the need for separate image acquisition
  • Very low dose radiation exposure (less than the equivalent of one day of natural background radiation)2
