The Findings of Magnetic Resonance Imaging in Thyroid Masses

Abstract

We studied the findings of magnetic resonance imaging in thyroid masses. The study subjects included 44 cases of thyroid disease (16 of follicular adenoma, 16 of adenomatous goiter, 10 of papillary carcinoma, and 2 of follicular carcinoma). We compared 5 variables (irregularity of margin, heterogeneity of tumor, invasion to out of thyroid gland, pseudocapsule, and enhancement effect). The findings suggest that identifying irregularity of margin is the most useful finding in diagnosing a thyroid tumor as malignant.
