Abbreviation Description, Definition
Tissue mapping in specific compartments
ABM Adipose bone marrow
TV Total volume of the body (from ankle to wrist), without INF
TVV Total visceral volume: includes intrathoracic and intraabdominal volume.
TSV Total somatic volume (TV without TVV).
TLT Total lean tissue
VLT Visceral lean tissue: includes lean tissue of intrathoracic and intraabdominal organs.
SLT Somatic lean tissue: mostly muscles
TAT Total adipose tissue (without INF)
SAT Somatic adipose tissue (TAT without VAT)
TAST Total adipose soft tissue (TAT without ABM)

SCAT Subcutaneous adipose tissue (SAST without IMAT)
IMAT Intermuscular adipose tissue (SAST without SCAT)
VAT Visceral adipose tissue (IAAT + MAT without INF)
IAAT Intraabdominal adipose tissue: retroperitoneal and intraperitoneal (mesenteric, omental) fat depots (without INF)
