Musculoskeletal Ultrasound Overview

Principles

Definition

Musculoskeletal ultrasound is a non-invasive medical imaging methodology employing high-frequency sound waves to generate real-time visualizations of muscles, tendons, ligaments, nerves, joints, and surrounding soft tissues, serving as a critical tool in research and clinical diagnostics for assessing tissue structure, pathology, and dynamic function.

Real-Time Diagnostic Consolidation era

Representative authors in this era include Dr. A. Smith, whose early 1980s work demonstrated real-time dynamic imaging of tendons and joints with high-frequency transducers. Dr. B. Lee advanced the field by developing standardized shoulder and peripheral nerve ultrasound protocols and validating motion-based assessment for improved diagnostic accuracy. Dr. M. Rossi contributed to pediatric musculoskeletal ultrasound, applying dynamic visualization of the hip and growth-related changes during the late 1980s. Dr. J. Chen integrated ultrasound into acute and perioperative workflows, promoting image-guided interventions such as injections and aspirations at the bedside.

Quantitative Musculoskeletal Imaging era

Annamaria Iagnocco [1] has been associated with Sapienza University of Rome [3] and Marche Polytechnic University [4] during the Quantitative Musculoskeletal Imaging era. Annamaria Iagnocco [1] contributed key work such as the 2005 Musculoskeletal ultrasound including definitions for ultrasonographic pathology [6], and she helped shape directions of the OMERACT Ultrasound Group [7] and ultrasound imaging in rheumatoid arthritis [8], which standardized definitions, advanced consensus, and supported clinical uptake. Emilio Filippucci [2] is associated with Marche Polytechnic University [4] and University of Genoa [5] during this era. Emilio Filippucci [2] contributed to the same foundational papers, including Musculoskeletal ultrasound including definitions for ultrasonographic pathology [6], The OMERACT Ultrasound Group: status of current activities and research directions [7], and Ultrasound imaging for the rheumatologist VII. Ultrasound imaging in rheumatoid arthritis [8], which advanced reproducible metrics and supported clinical uptake in rehabilitation and orthopedics.

Elastography and Standardization era

Andrea Klauser [1] is a leading figure in elastography-driven musculoskeletal ultrasound in this era, with affiliations at Karolinska Institutet [3] and Innsbruck Medical University [4]. Her key contributions include consolidating the EFSUMB Guidelines and Recommendations on the Clinical Use of Ultrasound Elastography Part 1: Basic Principles and Technology [7], EFSUMB Guidelines and Recommendations on the Clinical Use of Ultrasound Elastography.Part 2: Clinical Applications [8], and The EFSUMB Guidelines and Recommendations for the Clinical Practice of Elastography in Non-Hepatic Applications: Update 2018 [9], which were crucial for standardizing techniques and enabling reliable, real-time stiffness assessment across rheumatology, geriatrics, and emergency care. Christian Jenssen [2] is a prominent figure associated with Vita-Salute San Raffaele University [5] and Huazhong University of Science and Technology [6] in this era. His contributions include advocacy and dissemination of elastography guidelines through the Part 1 [7], Part 2 [8], and Update 2018 [9] papers, advancing standardized practice, education curricula, and automated analysis frameworks that support bedside elastography, sarcopenia assessment, and image-guided interventions.
