Role of Virtual Touch Tissue Quantification in Hashimoto's Thyroiditis

Area of Science:

• Medical Imaging
• Endocrinology
• Rheology

Background:

• Hashimoto's thyroiditis (HT) is an autoimmune disease affecting the thyroid gland.
• Accurate diagnosis and differentiation of HT-related thyroid dysfunctions are crucial for effective management.
• Non-invasive diagnostic tools are needed to assess thyroid tissue characteristics.

Purpose of the Study:

• To evaluate the efficacy of Virtual Touch Tissue Quantification (VTQ) in diagnosing Hashimoto's thyroiditis (HT).
• To assess VTQ's ability to differentiate between various HT-related thyroid dysfunctions (hyperthyroidism, euthyroidism, hypothyroidism).

Main Methods:

• VTQ was used to measure shear wave velocity (SWV) in 200 HT patients and 100 healthy controls.
• The diagnostic performance of VTQ for HT was assessed using the area under the receiver operating characteristic curve (A_Z).
• SWV values were compared across HT subgroups (hyperthyroidism, euthyroidism, hypothyroidism) using ANOVA.

Main Results:

• Mean SWV was significantly higher in HT patients (2.32 ± 0.49 m/s) compared to controls (1.93 ± 0.33 m/s) (p < 0.001).
• VTQ demonstrated an A_Z of 0.734 for distinguishing HT from healthy thyroid tissue, with 82.5% sensitivity and 50.0% specificity at a cut-off of 1.86 m/s.
• Significant differences in mean SWV were observed among the HT subgroups: hypothyroidism (2.49 ± 0.46 cm/s), euthyroidism (2.20 ± 0.40 cm/s), and hyperthyroidism (2.07 ± 0.37 cm/s) (p < 0.05).

Conclusions:

• VTQ is a promising non-invasive technique for diagnosing Hashimoto's thyroiditis.
• VTQ can aid in distinguishing between different thyroid function states associated with HT.
• Further research may establish VTQ as a valuable tool in routine thyroid diagnostics.
