Quantitative Multi-Parameter MRI Evaluation of Hashimoto's Thyroiditis Changes After Dietary Interventions

Area of Science:

• Radiology
• Endocrinology
• Immunology

Background:

• Hashimoto's thyroiditis is a prevalent autoimmune condition.
• Limited research exists on multi-parametric MRI for diffuse thyroid lesions like Hashimoto's.
• Assessing disease progression in Hashimoto's thyroiditis requires advanced imaging techniques.

Purpose of the Study:

• To evaluate the utility of multi-parametric MRI in assessing Hashimoto's thyroiditis progression.
• To investigate the impact of dietary management on Hashimoto's thyroiditis using MRI and serological markers.
• To establish MRI as a quantitative tool for monitoring autoimmune thyroid disease.

Main Methods:

• 40 patients with Hashimoto's thyroiditis were randomized into intervention (dietary management) and control groups.
• Multi-parametric MRI, including T2-weighted imaging relative signal intensity (T2WI RSI) and water fraction, was performed at baseline and 6 months.
• Thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TGAb) levels were measured concurrently.

Main Results:

• The intervention group showed significant reductions in T2WI RSI and thyroid water fraction post-dietary management (P<0.05 and P<0.001, respectively).
• Significant decreases in TPOAb and TGAb levels were observed in the intervention group (P<0.05).
• The control group exhibited no significant changes in MRI parameters or antibody levels (P>0.05).

Conclusions:

• Multi-parametric MRI serves as a valuable quantitative method for assessing Hashimoto's thyroiditis.
• MRI provides an intuitive and sensitive approach to understanding and managing autoimmune thyroid disease.
• Dietary intervention demonstrates a measurable positive impact on Hashimoto's thyroiditis, trackable by MRI.
