Introduction Our group have developed a method to deconvolute whole body DXA scans into three images, each consisting uniquely of fat, lean, and bone masses. These images are being explored as more sensitive markers of risk for a variety of diseases. We asked if images of fat, lean, and bone distribution can be used to define natural phenotypical groupings and if these groupings are related to common risk factors for metabolic disease and bone fragility. Methods Participants were from the Shape ...

Introduction DXA regional body composition accuracy and precision are critically important in many clinical applications including monitoring lymphedema, performance training, and injury recovery. While total body composition measurements are highly precise, regional measurements exhibit lower precision partly due to inconsistencies in subject positioning. In particular, tissue overlap between body regions (such as breast tissue from the trunk overlying the arms, or hands overlapping the hip) li...

Anthropometry, Greek for human measurement, is a tool widely used across many scientific disciplines. Clinical nutrition applications include phenotyping subjects across the lifespan for assessing growth, body composition, response to treatments, and predicting health risks. The simple anthropometric tools such as flexible measuring tapes and calipers are now being supplanted by rapidly developing digital technology devices. These systems take many forms, but excitement today surrounds the intro...

Abstract Body composition measurements from DXA have been available since DXA technology was developed 30 years ago, but are historically underutilized. Recently, there have been rapid developments in body composition assessment including the analysis and publication of representative data for the US, official usage guidance from the International Society for Clinical Densitometry, and development of regional body composition measures with clinical utility. DXA body composition is much more than...
