Body composition imaging

Body composition analysis of the pig by magnetic resonance imaging.

Magnetic resonance imaging (MRI) was used to measure, in vivo, the volume of several organs and tissues of a total of 111 pigs (males and females) ranging in BW from 6.1 to 97.2 kg. In one experiment the in vivo MRI volumes were compared to tissue or organ weights obtained by dissection. For internal organs, the correlation (R2) between MRI volume and dissected weight ranged from 0.64 (SE of es...

Assessment of Body Composition Using Magnetic Resonance Imaging

Zooplankton body composition

I compiled literature on zooplankton body composition, from protozoans to gelatinous plankton, and report allometric relations and average body composition. Zooplankton segregate into gelatinous and non-gelatinous forms, with few intermediate taxa (chaetognaths, polychaetes, and pteropods). In most groups body composition is size independent. Exceptions are protozoans, chaetognaths, and pteropo...

Body fluid composition.

UNLABELLED Body fluid composition is maintained in a normal physiologic range by regulatory mechanisms that control sodium and water metabolism. A detailed knowledge of the homeostatic mechanisms will help in understanding the pathogenesis and management of disorders of sodium and water balance. OBJECTIVES After completing this article, readers should be able to: 1. Understand the distributio...

Body Composition in Paraplegia

Paraplegia leads to immobilisation associated with profound changes in body composition. The potential risks involved with these changes i.e. loss of lean tissue mass (LM) and bone mineral density (BMD) vs. gain in fat mass (FM) in body composition have implications for the health of the disabled individuals [1]. Body fat has been identified as a significant predictor of mortality in humans mak...
