“…In the Isodiri et al study, the mean ECI value of lymph nodes was also found to be lower than that of parathyroid lesions, which was consistent with our results. In the studies investigating the contribution of SWE in the differentiation of malignant and benign lymph nodes, the mean SWV values of benign lymph nodes were found to be between 1.52 and 2.71 m/s [21][22][23][24][25]. The mean SWV value of the lymph nodes in our study was 1.86 m/s.…”

Aims: The aim of this study was to prospectively assess the feasibility of the Virtual Touch tissue imaging quantification (VTIQ) method of shear wave elastography (SWE) for the discrimination of parathyroid lesions and to compare the lesions’ stiffness with that of cervical lymph nodes.Materials and methods: SWE using VTIQ was performed on 66 patients with 87 histopathologically proven parathyroid lesions (54 parathyroid adenomas and 33 parathyroid hyperplasia) and 29 patients with 31 inflammatory cervical lymph nodes. The mean SWVs of the lesions were compared and receiver operating characteristic (ROC) curve analysis was used to evaluate diagnostic performance.Results: The mean SWV of parathyroid adenomas (2.16±0.33 m/s) differed significantly from those of parathyroid hyperplasia and lymph nodes (1.75±0.28 m/s and 1.86±0.37 m/s respectively, p<0.001). Selecting a cutoff value of 1.92 m/s for diagnosing adenoma led to 80% sensitivity and 82% specificity (area under the curve [AUC]: 0.832 [95% confidence interval (CI): 0.742–0.921], p< 0.001).Conclusions: The VTIQ method of SWE can contribute to the differentiation of parathyroid adenoma from parathyroid hyperplasia and cervical lymphnodes.

“…Our results are in agreement with Lyshchik, et al, (2007), choi et al, (2015) and Cheng et al,(2016) [9,10,11] who found that the diagnostic accuracy of the muscle-to-lymph node strain index was high. There was a significant difference in mean strain index between the benign and metastatic lymph nodes: 0.8 ± 0.5 versus 4.4 ± 3.6, respectively (P < 0.01).…”

Abstract:In the clinical practice, there is many overlap in diagnostic criteria between benign and malignant lymph nodes by grayscale and Doppler sonography. This study was carried out on 30 patients who suffered from enlarged cervical lymph nodes examined with B-mode US, Doppler US and Sonoelastography in the Sonoelastography unit of the Radiology department of Tanta university hospitals to prospectively estimate the accuracy of sonoelastography in the differentiation between benign and malignant cervical lymph nodes. Sonoelastography had the highest sensitivity (92.1%), specificity (95.5%) and accuracy (93.3%) in the differentiation between benign and malignant cervical lymph nodes, so Sonoelastography is a promising technique that is easy and rapid non-invasive to perform and help identifying cervical lesions that are likely to be malignant to avoid hazards that found in tissue biopsy especially in patients with bleeding disorders.

“…For example, in one study assessing 55 cervical lymph nodes (24 benign: reactive, tuberculosis; 31 malignant: varied primary malignancies) with 2D-SWE versus FNA cytology as the reference standard found specificity was as high as 100% but sensitivity was only 41.9% for predicting malignancy (Table 3, 148). A more recent study assessed 100 histologically proven cervical lymph nodes (43 benign: reactive, Kikuchi disease, tuberculosis; 57 malignant: numerous primary malignancies) with pSWE and found a relatively higher sensitivity of 78.9% but a lower specificity of 74.4% for the discrimination of benign and malignant lymph nodes (Table 3, 149). …”

Elastography-based imaging techniques have received substantial attention in recent years for non-invasive assessment of tissue mechanical properties. These techniques take advantage of changed soft tissue elasticity in various pathologies to yield qualitative and quantitative information that can be used for diagnostic purposes. Measurements are acquired in specialized imaging modes that can detect tissue stiffness in response to an applied mechanical force (compression or shear wave). Ultrasound-based methods are of particular interest due to its many inherent advantages, such as wide availability including at the bedside and relatively low cost. Several ultrasound elastography techniques using different excitation methods have been developed. In general, these can be classified into strain imaging methods that use internal or external compression stimuli, and shear wave imaging that use ultrasound-generated traveling shear wave stimuli. While ultrasound elastography has shown promising results for non-invasive assessment of liver fibrosis, new applications in breast, thyroid, prostate, kidney and lymph node imaging are emerging.Here, we review the basic principles, foundation physics, and limitations of ultrasound elastography and summarize its current clinical use and ongoing developments in various clinical applications.
