ROLE OF DWI IN DIFFERENTIATING BENIGN AND MALIGNANT THYROID NODULES AND ITS COMPARISON WITH HISTOPATHOLOGY

Abstract :

Thyroid nodule is a discrete lesion, radiologically distinct from surrounding thyroid parenchyma. It may be benign or malignant. Sonography is the imaging modality to detect a thyroid nodule but it is operator dependent and is inferior in evaluation of extension. Non-contrast MRI is the favoured modality in cases with equivocal USG findings, extrathyroidal extension, in assessment of lymph node status, and in staging of diseases, which may help in providing appropriate case management. In conjunction with conventional sequences and with added new sequences like DWI, MRI may provide qualitative and quantitative information which helps in confident and accurate diagnosis of thyroid nodules.
