Introduction: The thyroid gland is the largest of all endocrine glands and is the only one which is amenable to direct physical examination and high resolution real-time grayscale sonography because of its superficial location. High Resolution Ultrasonography (USG) with Color Doppler is used to assess the nature of the lesion according to its vascularity and also the hemodynamic characteristics of the gland. Thus, the combination of Gray scale Sonography and Color Flow Doppler provide huge benefits and help in increasing the sensitivity, specificity and accuracy in distinguishing benign and malignant thyroid nodules. Nearly 50% of patients with a clinically palpable solitary thyroid nodule have avoided surgery because of thyroid ultrasound.

Aims and objectives: The present study is aimed to determine the role of high resolution USG in the evaluation of lesions of the thyroid with Fine-needle aspiration cytology (FNAC) correlation and compare it with other studies.

Materials and methods: This is a prospective study carried out on 50 patients (44 female and 6 male) who attended ENT or Surgery outpatient department/inpatient department (OPD/IPD) and were referred to the Department of Radio-Diagnosis for high resolution USG of neck at Rohilkhand Medical College and Hospital, Bareilly, Uttar Pradesh, India. This study was conducted for a period of one year from March 2015 to February 2016. The ultrasound machine used was GE LOGIQ V5.

Result and Conclusion: Our present study consisted of 50 cases which were clinically suspected suffering from thyroid dysfunction. Thyroid ultrasound was very efficient in picking up lesions in all 50 cases in our study. In comparison, to other studies our study gave a similar picture in terms of benign lesions being much more common than malignant lesions. The most common benign lesion determined in our study was colloid goiter which was the most common benign lesion in many other studies. In comparison to other studies, we were able to detect malignant nodules with a better specificity. Chronic thyroiditis was also very efficiently detected using ultrasound in our study.
