Abstract

PURPOSE OF REVIEW:

Cross-sectional (C-S) imaging is now commonly used to measure body composition in clinical studies. This review highlights the advantages, limitations and suggested future directions for this technique.

RECENT FINDINGS:

Current understanding of C-S imaging reproducibility, tissue identification and segmentation methods, comparison between imaging techniques and estimates of whole body composition using a single image are described.

SUMMARY:

C-S imaging can reliably measure muscle and fat distribution and uniquely discriminate between intra-abdominal organ and muscle component of fat-free mass. It precisely tracks changes within an individual, but is less able to distinguish true differences in whole body estimates between individuals.
