Shear-Wave Elastography-Diagnostic Value in Children with Chronic Autoimmune Thyroiditis

Area of Science:

• Pediatric Endocrinology
• Medical Imaging
• Rheumatology

Background:

• Chronic autoimmune thyroiditis (CAT) is the most prevalent thyroid condition in children.
• Current diagnostic methods like ultrasound may suggest CAT, but additional tools are beneficial.
• Shear-wave elastography (SWE) has shown effectiveness in assessing thyroid stiffness (TS) in adults with CAT.

Purpose of the Study:

• To evaluate the utility of SWE in diagnosing CAT in pediatric patients.
• To compare thyroid stiffness measurements in children with CAT, healthy children, and adults with CAT.

Main Methods:

• A study involving 50 children diagnosed with CAT, 50 healthy children, and 50 adults with CAT.
• Evaluation included bioimmunochemical analysis, thyroid ultrasound, and SWE measurements.
• SWE elastography was performed using the Aixplorer Mach 30 device.

Main Results:

• Children with CAT exhibited significantly lower mean thyroid stiffness (TS) values compared to adults with CAT (15.51 ± 4.76 kPa vs. 20.96 ± 6.31 kPa; p < 0.0001).
• TS values in children with CAT were significantly higher than in age-matched healthy controls (15.51 ± 4.76 kPa vs. 10.41 ± 2.01 kPa; p < 0.0001).
• These findings indicate distinct elastographic profiles across the groups.

Conclusions:

• Shear-wave elastography (SWE) is a promising diagnostic tool for evaluating autoimmune thyroid pathology in children.
• SWE provides objective measurements of thyroid stiffness, aiding in the diagnosis of pediatric CAT.
• Further research can establish SWE as a standard non-invasive method for pediatric thyroid assessment.
