Abstract

Objectives

Loss of muscle quantity and function is associated with frailty and reduced quality of life. Sonography is a simple option to quantify muscle mass, which could be included into routine diagnostic workup. This study was designed to prospectively evaluate sonographic measurement and to compare it with established measurements of muscle quantity and function.

Methods

Between March 2020 and May 2022, 723 patients were enrolled in the study. Psoas muscle area index (PMAI) and psoas muscle thickness height index (PMTI) were quantified. Thigh muscle thickness indices (TMTI) were either measured without compression (fTMTI) or under compression (cTMTI). Variation coefficient (VC) as well as intra- and inter-observer reliability were analyzed. The reliability and reproducibility of the sonographic morphometry were assessed using two examiners. Sonographic morphometry was compared with established measurements of muscle using computed tomography and hand grip strength, respectively.

Results

In 156 patients, sonographic indices were compared with corresponding CT indices. Of the 723 patients included, sonographic indices were compared with hand strength in 429 patients. Interobserver and intraobserver variability showed better results for the femur indices than for the psoas indices (correlation coefficient: 0.8697/0.9118 vs 0.7502/0.7319). Psoas muscle indices correlated best with the reference standard of the SMI. The optimal cut-off for each muscle index for determining muscle loss according to the SMI and hand grip strength was calculated.

Conclusion

Sonography can simplify muscle measurement and should be used in the future. Sonographic muscle indices have the potential to simplify evaluation, especially in risk groups such as patients with liver cirrhosis or other wasting disorders.

使用已确定的肌肉标记对超声肌肉测量进行评估
肌肉数量和功能的丧失与身体虚弱和生活质量下降有关。超声波检查是量化肌肉质量的一种简单方法,可将其纳入常规诊断工作中。本研究旨在对超声波测量进行前瞻性评估,并将其与已有的肌肉数量和功能测量方法进行比较。

期刊介绍: The Journal of Ultrasound in Medicine (JUM) is dedicated to the rapid, accurate publication of original articles dealing with all aspects of medical ultrasound, particularly its direct application to patient care but also relevant basic science, advances in instrumentation, and biological effects. The journal is an official publication of the American Institute of Ultrasound in Medicine and publishes articles in a variety of categories, including Original Research papers, Review Articles, Pictorial Essays, Technical Innovations, Case Series, Letters to the Editor, and more, from an international bevy of countries in a continual effort to showcase and promote advances in the ultrasound community. Represented through these efforts are a wide variety of disciplines of ultrasound, including, but not limited to: -Basic Science- Breast Ultrasound- Contrast-Enhanced Ultrasound- Dermatology- Echocardiography- Elastography- Emergency Medicine- Fetal Echocardiography- Gastrointestinal Ultrasound- General and Abdominal Ultrasound- Genitourinary Ultrasound- Gynecologic Ultrasound- Head and Neck Ultrasound- High Frequency Clinical and Preclinical Imaging- Interventional-Intraoperative Ultrasound- Musculoskeletal Ultrasound- Neurosonology- Obstetric Ultrasound- Ophthalmologic Ultrasound- Pediatric Ultrasound- Point-of-Care Ultrasound- Public Policy- Superficial Structures- Therapeutic Ultrasound- Ultrasound Education- Ultrasound in Global Health- Urologic Ultrasound- Vascular Ultrasound
