Ultrasound for body composition assessment: a narrative review.

Ultrasound has become an increasingly valuable tool for the assessment of body composition, offering several applications and indications in clinical practice. Ultrasound allows bedside evaluation of muscle mass, fat compartments, and extravascular water, providing a cost-effective, portable, and accessible alternative to traditional methods, such as Dual-energy X-ray Absorptiometry (DEXA), Bioelectrical Impedance Analysis (BIA), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI). It is particularly useful in evaluating conditions, such as malnutrition, sarcopenia, and sarcopenic obesity, which require poor muscle mass to establish a diagnosis.

Executive summary of the consensus document for the training and development of clinical ultrasound in Internal Medicine: Recommendations from the Clinical Ultrasound Working Group of the Spanish Society of Internal Medicine (GTECO-SEMI).

Introduction: Given the increasing adoption of clinical ultrasound in medicine, it is essential to standardize its application, training, and research.

Objectives And Methods: The purpose of this document is to provide consensus recommendations to address questions about the practice and operation of clinical ultrasound units. Nineteen experts and leaders from advanced clinical ultrasound units participated.
