Acoustic Structure Quantification Analysis of the Thyroid in Patients with Diffuse Autoimmune Thyroid Disease

Area of Science:

• Medical Imaging
• Endocrinology
• Rheumatology

Background:

• Diffuse autoimmune thyroid disease (AITD) encompasses conditions like chronic autoimmune thyroiditis (CAT) and Graves' disease (GD).
• Accurate differentiation between normal and pathological thyroid parenchyma is crucial for effective AITD management.

Purpose of the Study:

• To evaluate the efficacy of acoustic structure quantification (ASQ) in differentiating normal thyroid tissue from pathological tissue in AITD patients.

Main Methods:

• A prospective study involving 83 subjects (43 CAT, 22 GD, 18 healthy volunteers) was conducted.
• Acoustic structure quantification (ASQ) values were measured and compared between groups.
• Statistical analysis was performed to determine significant differences and identify optimal cutoff values.

Main Results:

• ASQ values were significantly lower in healthy subjects compared to patients with CAT and GD (p < 0.001).
• No significant difference in ASQ values was observed between CAT and GD patients (p = 0.23).
• An ASQ cutoff value of 103 demonstrated high sensitivity (83%) and specificity (89%) for predicting diffuse thyroid pathology.

Conclusions:

• Acoustic structure quantification (ASQ) is a valuable tool for assessing thyroid parenchyma in patients with diffuse autoimmune thyroid disease.
• ASQ can effectively differentiate normal thyroid tissue from pathological tissue associated with CAT and GD.
