The Application Of Diffusion-Weighted And Dynamic Enhanced MRI In The Diagnosis Of Thyroid Disease

Objective: To evaluate the clinical value of diffusion- weighted MR imaging and dynamic enhanced MR imaging in the differential diagnosis of benign and malignant thyroid lesions. Methods: The first part of the study was to analyze and summarize the characteristics of thyroid diseases in the diffusion-weighted MR images; the second part was to analyze the dynamic enhancement features of 42 cases with thyroid lesions. Results: The ADC values difference between benign and malignant thyroid lesions was significant (P < 0.05) with b value of 300 s/mm~2. When b value is 500s/mm~2 and 800 s/mm~2, the difference between benign and malignant lesions was insignificant (P > 0.05). There was significant difference in the maximum rise slope between benign and malignant thyroid lesions (t = 5.72, P < 0.001). Conclusion: Diffusion-weighted MR imaging and dynamic enhanced MR imaging contributed to the diagnosis and differential diagnosis of benign and malignant thyroid lesions.
