Editorial on precise body composition imaging evaluation and clinical application
摘要
Abstract
Abnormal body composition,including skeletal muscle attenuation,visceral fat accumulation,intramuscular fat infiltration,and bone mass decline,is closely associated with metabolic diseases,adverse tumor prognosis,frailty in the elderly,osteoarticular injuries,and osteoporotic fractures.BMI,waist circumference,and bioelectrical impedance analysis can only provide a rough assessment of body shape but fail to differentiate fat distribution,muscle mass,and bone microstructure,making them inadequate for precise diagnosis and treatment.Imaging techniques centered on dual-energy X-ray absorptiometry,quantitative computed tomography,conventional CT body composition analysis,and magnetic resonance water-fat separation imaging enable layered quantitative evaluation of bones,skeletal muscles,subcutaneous,and visceral fat,serving as the mainstream approach for precise body composition assessment today.With advancements in artificial intelligence and opportunistic imaging analysis,body composition evaluation has transitioned from a research tool to routine clinical application.This article systematically reviews the principles,advantages and disadvantages,quantitative indicators,and multidisciplinary clinical value of various body composition imaging techniques,summarizes current technical limitations,and explores the prospects for standardized system construction and intelligent applications in China,providing a reference for promoting precision medicine in body composition.关键词
