Hashimoto's Thyroiditis

Abstract

Thyroiditis is a general term for several inflammatory thyroid disorders ranging from autoimmune, infective, and drug induced to ionizing radiation. Ultrasound is the imaging modality of choice in the evaluation of thyroid-related pathologies. B-mode and color Doppler provide for a noninvasive and sensitive method in the evaluation of thyroiditis. Elastography is a recent modality of ultrasound. It helps in differentiating benign from malignant diseases. A definite diagnosis is often not possible on ultrasound alone, correlation of ultrasonography findings with elastography and clinical and biochemical parameters help us reach an appropriate diagnosis in most of the cases and further imaging is seldom warranted.
