“Role Of Elastography In Thyroid Nodules And It's Histopathological Correlation .”

Abstract

Aims & Objective:To determine the ultrasound elastography findings in thyroid nodules. To evaluate the
diagnostic accuracy of elastography of thyroid nodules in differentiatingbenign and malignant nodules. To
correlate the ultrasound elastography with the FNA and/or histopathology findings.Methods: A prospective study
of 50 patients presenting with thyroid swelling was carried out by grey scale & Color Doppler ultrasound with
ultrasound elastography and findings were correlated with histo-pathological results. Result: In our prospective
observational study of 50 patients with thyroid nodulesincidence of thyroid nodules is more common in the young
and middle aged patients(15-40 years).All the pathologies are much more common in females than in males
(male:female ratio=1:9)The benign pathologies(78%) are observed much more often than the
malignantones(22%).Various B-mode ultrasound characteristics of thyroid nodules like irregular
margins,microcalcifications, absence of halo, increased intralesional vascularity and hypoechogenicity, help to
characterize the thyroid nodules and are indicative of being suspicious of malignancy. Conclusion: The combined
use of thyroid US elastography with B-mode US may improve the ability to discriminate benign from malignant
thyroid nodules and reduce the number of needed FNAs.
