Thyroid Nodule Delineation: Role of Ultrasound Elastography
Journal Title: PARIPEX-Indian Journal of Research - Year 2016, Vol 5, Issue 9
Abstract
Background: To check upon thyroid nodule (detected clinically or otherwise), with the possibility of thyroid cancer being real (~5%), it’s important to evaluate them at the earliest. Objective: To evaluate qualitative elastography patterns by using gray-scale and Doppler ultrasound (US) in patients presenting with thyroid nodules. Methodology: Total 12 consecutive participants were selected and US & guided FNAB were performed. The results were recorded according to the Bethesda 2008 classification. Links between each gray-scale, power Doppler US feature, and cytology and the different elastographic patterns were calculated by applying Mc-Naemer’s chi-square test. Observations: Of 12 thyroid nodules that were examined on qualitative elastography, the strain pattern included a pattern type 1 in 1 patients (8.3%), pattern 2 in 6 patients (50%), and pattern 3 in 4 patients (33%). Pattern 4 was found in one (8.3%) case. Nine thyroid nodules (75%) showed colloid goitre, Two (16.7%) showed malignant and 1 (8.3%) showed thyroidits on cytopathological sample assessment. .Conclusion: Although US elastography is easy to perform and not very time consuming, the intra-observer variability is high, thereby decreasing the US examination accuracy in differentiating benign from malignant thyroid nodules. The results must be corroborated in a larger population study.
