In this article, based on two clinical examples, the possibilities of multiparametric ultrasound in the differential diagnosis of metastatic and lymphoproliferative changes in lymph nodes in primary-multiple malignant tumors, including breast cancer and lym - phoma, are evaluated. Multiparameteric ultrasound includes B-mode, color and energy Doppler imaging, strain elastography, shear wave elastography and contrast-enhanced ultrasound (CEUS). Standardization and reproducibility of these ultrasound techniques will allow to objectify the study, obtaining specific indicators of shear wave velocity in the zones of interest and specific signs of contrast enhancement, which can be used as impor tant differential diagnostic tool in oncology.

Objective: To compare the diagnostic value of shear wave elastography (SWE) and real-time elastography (RTE) in the diagnosis of benign and malignant thyroid nodules. Methods: A total of 34 patients who ever received thyroidectomy in our hospital from January 2016 to January 2018 were identified. Meanwhile, all the patients received SWE and RTE before surgery, and all the diagnoses were confirmed by pathological examinations. With respect to SWE technique, the Subject Operating Characteristics (ROC) curves were drawn, in order to obtain the optimal threshold and then make differential diagnoses of benign and malignant thyroid nodules. In terms of RTE, the Rago 5 scoring method was utilized to make differential diagnoses of benign and malignant thyroid nodules. Besides, the pathological examinations after surgery could be considered as the golden standard. At last, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of SWE and RTE were calculated, respectively. Results: A total of 51 thyroid nodules were identified, and 41 nodules were benign, 10 nodules were malignant. On the basis of ROC curves, with respect to SWE, the best threshold for differential diagnosis of benign and malignant thyroid nodules is 38.3 kPa. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of SWE were 72.7% (8/11), 85% (34/40), 82.4% (42/51), 68.4% (13/19), and 87.5% (35/40), respectively. And the diagnostic indicators of RTE were 81.8% (9/11), 87.5% (35/40), 84.3% (43/51), 73.7% (14/19), and 90.0% (36/40). The sensitivity of quasi-static elastography in differential diagnosis of benign and malignant thyroid nodules with diameter ≤1 cm was 87.5% (7/8), and the sensitivity of SWE was 50.0% (5/10). In addition, the accuracy of SWE in differential diagnosis of benign and malignant thyroid nodules with diameter ≥3 cm was 100% (6/6), and the accuracy of RTE for this kind of thyroid nodules was 66.7% (4/6). Conclusion: Both SWE and RTE technology have good application value in differential diagnosis of benign and malignant thyroid nodules. But, SWE is preferable when making diagnosis of benign and malignant thyroid nodules with diameter ≥3 cm, and RTE was superior in detecting benign and malignant thyroid nodules with diameter ≤1 cm.

Abstract Background Fine-needle aspiration is the gold standard, but malignancy rate of the indeterminate cytology is reported as 20-50 %. We aimed to evaluate the efficacy of shear wave elastography (SWE) added to ultrasonogram in the differential diagnosis of thyroid nodules. Methods We retrospectively reviewed the medical records of 258 consecutive patients. Thyroid nodules were divided in to 4 categoies according to maximum elasticity (EMax) and nodule depth/width (D/W) ratio; Category 1 (EMax ≥42.6 kPa & D/W<0.9), Category 2 (EMax <42.6 kPa & D/W<0.9 ), Category 3 (EMax ≥42.6 kPa & D/W≥ 0.9) and Category 4 (EMax<46.2 kPa & D/W≥ 0.9 ). The cutoff value of EMax was set using ROC curve analysis to predict nodular hyperplasia (NH) from follicular neoplasm (FN). Cutoff value ​​for nodule D/W ratio was set using ROC curve analysis for malignancy. Results NH was the most prevalent pathology group in category 1, FN in category 2 and PTC in category 3. The category 3 demonstrated the highest rate of malignancy (81.8%) and had 55.4% sensitivity and 90% specificity for predicting malignancy. When assessing the benign pathology of NH in follicular patterned lesion, category 1 demonstrated the highest NH prevalence of 88.9% (34/37) and had 73.9% sensitivity and 85.0% specificity. Conclusion The performance for malignancy was highest in category 3 and predictive ability for benign pathology of NH in follicular lesion was highest in category 1. So the information of EMax and nodule D/W ratio was useful to predict the pathology of thyroid nodules
