Role of Ultrasonography in Thyroid Nodules with Pathological Correlation

Abstract

Background: Thyroid nodule imaging had been a challenging task. Ultrasound has been the modality of choice for detection & evaluation of these lesions. This study was done to identify the accuracy of various imaging features in thyroid nodules that are associated with benignity  and malignancy and the overall accuracy of ultrasound in determining malignant nodules. The objective of the study are: (1) Ultrasonographic evaluation of thyroid to characterize the thyroid disease and nodules (benign vs malignant) and their morphologic evaluation. (2) Sensitivity and Specificity on the basis of radiological, and cytopathological correlation for suspected thyroid lesions. Subjects and Methods: A total of seventy patients (70) of both sexes and different age group, meeting the inclusion criterion, were the part of present prospective study. The cases referred to the Department of Radio-diagnosis and imaging from OPD/IPD of Saraswathi Institute of Medical sciences, Hapur from October’2017 to July’2019. An informed consent was taken from all the patients subjected for evaluation. Results: The collective data was analysed for Ultrasound findings of thyroid nodule which presented clinically as solitary or multiple thyroid nodules. The total number of cases analysed was 70 out of which 48 were found to have solitary/multinodular lesions clincally. On ultrasound evaluation out of 48 patients 38   had solitary/multinodular lesions. Conclusion: High resolution sonography is recommended as the primary imaging modality in evaluation of thyroid diseases. It has a high sensitivity and specificity in the diagnosis of thyroid diseases.
