Ultrasound elastography in the head and neck. Part I. Basic principles and practical aspects

Area of Science:

• Medical Imaging
• Biophysics
• Oncology

Background:

• Ultrasound elastography (USE) is an emerging imaging technique measuring tissue stiffness.
• Real-time USE modes are now available on clinical ultrasound machines, driving extensive research.
• Preliminary data indicate USE's accuracy in distinguishing benign from malignant conditions across various tissues.

Purpose of the Study:

• To provide an overview of fundamental principles of various USE technologies.
• To discuss current investigations of USE in the head and neck region.
• To address practical considerations for optimizing USE performance in this anatomical area.

Main Methods:

• Review of current Ultrasound Elastography technologies.
• Discussion of research applications in the head and neck.
• Analysis of practical performance optimization.

Main Results:

• USE shows promise in differentiating benign and malignant conditions.
• Various USE technologies are under investigation for head and neck applications.
• Optimal performance strategies for head and neck USE are considered.

Conclusions:

• Ultrasound elastography is a valuable tool for assessing tissue elasticity.
• Further research and practical considerations are key for head and neck applications.
• USE has significant potential in both oncologic and non-oncologic diagnoses.
