Clinical Trial Summary
1. To develop an artificial intelligence assisted diagnostic model for sarcopenia based on
ultrasound images;
2. To develop artificial intelligence classification and regression models for auxiliary
diagnosis of sarcopenia, patient strength estimation, and other functions based on
ultrasound image data.
Description:
Sarcopenia is a syndrome of age-related muscle mass loss and muscle function decrease, which
can be comorbid with a variety of diseases and interacts extensively with various disease
states to influence disease prognosis. Diseases such as cancer, diabetes, chronic kidney
disease, and rheumatoid arthritis can accelerate the process of muscle loss by affecting
myogenic cell regeneration, interfering with protein synthesis, increasing protein
consumption, and enhancing protein degradation by the ubiquitination pathway, and the decline
in motor function will, in turn, further worsen the prognosis of the disease. Despite some
regional differences, the prevalence of sarcopenia has been found to exceed 10%. Early
identification of the potential risk of sarcopenia and early intervention in the early stages
of muscle mass and function impairment is one of the most important steps to improve the
quality of life of older adults.
Currently, the diagnosis of sarcopenia relies on three features: loss of muscle mass, loss of
muscle strength, and loss of physical performance. At present, physicians usually use
bioelectrical impedance analysis (BIA) or dual-energy X-ray absorptiometry (DXA) to determine
skeletal muscle mass index SMI to measure muscle mass, grip strength test to measure muscle
strength, gait speed or tools such as SPPB scores to assess physical performance. A diagnosis
of sarcopenia can be made when a subject experiences a decrease in SMI combined with a
decrease in grip strength or a decrease in gait speed.
In the field of medical imaging, researchers have been working to explore and validate
appropriate imaging tools and markers to diagnose and evaluate sarcopenia. The common methods
for deep mining of medical imaging include radiomics and machine learning, usually by
analyzing the texture features of muscles at specific sites to quantify muscle function or
segmenting skeletal muscles accurately in two dimensions or three dimensions to quantify
muscle mass. Compared to computed tomography (CT) or magnetic resonance imaging (MRI),
ultrasound is a more accessible and less costly medical imaging technique, especially in low-
and middle-income regions. Ultrasound can be used to conveniently scan local muscles and
obtain muscle characteristics such as muscle thickness, cross-sectional area, and pennation
angle. Our previous studies have demonstrated that SMI in older adults can be accurately
estimated by using muscle thickness at four sites together with basic information such as age
and body mass index (BMI), and have found in cross-regional validation that the stability of
estimates can be maintained across communities with very different ethnic proportions.
However, several existing large studies on ultrasound in sarcopenia are currently focusing
only on muscle morphological measurements, ignoring the large amount of hidden ultrasound
image information. At the same time, the flexibility of the scanning process has led to
greater resistance from radiomics or deep learning tools to use the images for artificial
intelligence classification than CT or MRI.
Fronted with such a dilemma, we attempted to establish an intelligent risk grading system for
sarcopenia, based on multidimensional data including basic information such as age and BMI,
ultrasound measurements, and original image content, to complete the risk grading of
sarcopenia in older adults in a one-stop manner, so as to realize the rapid screening and
classification of potential sarcopenia populations for further clinical management.
