Benign Nodules

Benign and malignant thyroid cancer diagnosis is crucial. Our study intends to evaluate the role of shear wave elastography (SWE) and thyroid imaging report and data system (TI-RADS) in diagnosing the benign and malignant thyroid nodules. 100 thyroid nodules patients were recruited and evaluated by SWE and TI-RADS before fine needle biopsy and/or surgery. The maximum elastic index (Emax), mean elasticity index of thyroid nodules (Emean), minimum elastic index (Emin) and elastic ratio (ER) was measured and compared between different imaging. Ultrasound diagnosis showed solid nodules with significant hypoechoic, unclear boundary, and microcalcification. TI-RADS value was measured based on suspected ultrasound features. Combination of SWE and TI-RADS was performed. Among the 100 nodules, 38 were benign (38.0%), 62 were malignant (62.0%), and malignant nodules had significantly elevated SWE and TI-RADS compared with benign nodules (P < 0.001). The optimal SWE threshold for Emax was 51.95 kPa, with a sensitivity of 81.44% and specificity of 83.19%. There were two methods for combining SWE and TI-RADS. One was sequential detection, with a specificity of 95.80%, positive similarity ratio of 18.16 and PPV of 96.73%; the other was parallel detection method with a sensitivity of 94.85%, negative similarity ratio of 0.07 and PPV of 90.00%. Our results suggest that combination of SWE and TI-RADS might be applied to identify benign and malignant thyroid cancers.

Thyroid nodules are a common pathology found in 50 to 60% of otherwise healthy people. Diagnostic imaging techniques are help discriminating between benign and malignant nodules, while fine needle aspiration is still a gold standard. Shear wave elastography, a recent imaging technique, holds the promise to become reliable diagnostic tools and is currently used in combination with ultrasound. We here report data obtained in a series of 52 thyroid nodules analysed by means of elastography, as well as conventional and Doppler ultrasound. We found no differences in age, nodule and thyroid volume, length, width, thickness and maximum diameter between benign and malignant lesions. Several sonographic patterns are considered to be predictive of malignancy, out of which we only found the intranodular blood flow to be statistically significant. By the means of shear wave elastography we have first assessed tissue elasticities, which are shown in a range of colours, depending on tissue elasticity/stiffness. Then, we have measured and recorded four parameters automatically displayed by the system, namely SWE-mean, SWE-max, SWE-SD and SWE-ratio. Data analysis showed all these quantitative parameters had good sensitivity, specificity, positive predictive value, negative predictive value and area under the curve, as calculated by the ROC curve. As with these parameters, the cut-off points were lower than in literature, still able to indicate reliable diagnoses, which were confirmed by histopathological exam. Our conclusion is that shear wave elastography has great potential for reliably and accurately diagnosing thyroid malignancies.
