Ultrasonography01:17

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...

Summary
This summary is machine-generated.

Real time sonoelastography (SE) aids in diagnosing superficial lymphadenopathy. Hardness on over 50% of the node surface or a strain ratio (SR) greater than 1.5 suggests malignancy.

Ultrasonographic Evaluation of Salivary Glands for Sjogren's Syndrome: Diagnostic and Monitoring Insights

Published on: October 13, 2023

Area of Science:

  • Medical Imaging
  • Diagnostic Ultrasound
  • Oncology

Background:

  • Superficial lymphadenopathy diagnosis can be challenging.
  • Real-time sonoelastography (SE) offers a non-invasive method to assess tissue stiffness.

Purpose of the Study:

  • To provide a comprehensive overview of real-time sonoelastography applications in diagnosing superficial lymphadenopathy.
  • To illustrate typical elastographic appearances of benign and malignant lymph nodes.

Main Methods:

  • Review of technical aspects of performing SE.
  • Illustration of elastographic scores and critical appraisal of the strain ratio (SR).
  • Mention of shear wave elastography as a novel technique.

Main Results:

  • Hardness on >50% of the node surface is a fair indicator of malignancy.
  • A strain ratio (SR) > 1.5 is a fair to good indicator of malignancy.

Conclusions:

  • Real-time sonoelastography shows promise in differentiating benign from malignant lymph nodes.
  • Further research is needed to standardize SE applications and understand diverse disease appearances.
