“…According to international guidelines [1,2,4,6], ultrasound-based elastographic methods can be divided into shear wave elastography (SWE) and strain elastography (SE). The SWE techniques measure the speed of the shear waves generated in the tissues by either an external mechanical push or an ultrasound radiation force impulse (ARFI).…”

“…The technique has been described in detail in the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) and World Federation for Ultrasound in Medicine and Biology (WFUMB) guidelines [1,2,4,6,45] and also by others [46]. TE has been used for liver stiffness measurement (LSM) both in children and adults [1,2,47,48].…”

“…Ultrasound elastography is a useful non-invasive tool for the diagnosis of liver fibrosis in adults [1][2][3][4][5][6][7]. It plays a similar role in children, with some differences in the confounding factors and in the etiological spectrum of the liver disease; however, guidelines and recommendations have not been published yet.…”

Featured Application: In this review we present and discuss the published literature on the use of ultrasound-based liver elastography in children. The published data show that all the available shear wave elastography techniques are feasible and accurate for the assessment of liver fibrosis in children with diffuse liver disease due to several etiologies. For the assessment of focal liver lesions evidences are limited and no conclusion can be drawn so far.Abstract: Studies performed using transient elastography (TE), point shear wave elastography (pSWE) and two-dimensional shear wave elastography (2D-SWE) have shown that these techniques are all feasible and accurate in children for the evaluation of liver fibrosis due to several etiologies. However, for some specific pediatric pathologies, such as biliary atresia, the evidence is still limited. As shown in adults, inflammation is a confounding factor when assessing fibrosis severity and care should be taken when interpreting the results. Due to the scarce comparative data between serological tests and elastography techniques in children, a definite conclusion regarding which is the best cannot be drawn. Neither non-invasive elastographic techniques nor laboratory scores allow determination of the presence and the degree of inflammation, necrosis, iron or copper deposits.

“…There are many reports on the accuracy of elastography for diagnosing solid lesions of the breast [14], thyroid [15,16], liver [17], prostate [18], rectum [19], and lymph nodes [20]. However, to the best of our knowledge, few studies have evaluated the success of US elastography for increasing the sensitivity of conventional US for discriminating between benign and malignant renal masses [21][22][23][24][25].…”

Aims: To investigate the diagnostic accuracy of shear-wave elastography (SWE) for assessing malignant and benign kidneymasses.Materials and methods: Forty patients with solid renal masses underwent US elastographic evaluation. SWE values of the lesions and adjacent cortical renal parenchyma and SWER were detected prospectively. Malignant tumors were recorded as group 1 and benign tumors were recorded as group 2.Results: The highest elasticity values were 27.27±25.66 kPa for group 1 and 16.13±8.89 kPa for group 2. The mean±SD elasticity values for adjacent renal cortex for groups 1 and 2 were 2.7±2.08 and 2.75±1.35, respectively. For group 1, a negative correlation was observed between the age of the patients and SWER value (p=0.047, rs=‑0.401). There was also a negative correlation between the SWER value and the SWE value of adjacent renal cortex (p=0.004, rs=‑0.555).Conclusion: SWE is a noninvasive method that provides quantitative elasticity informationon tissues. Overlaps among different types of renal lesions may be due to heterogeneity of the lesions. Larger studygroups may clarify the other factors affecting SWE values under both normal and pathological conditions.

“…A short-duration acoustic push pulse leads to localized displacements and shear waves are generated. The velocity of transverse shear waves is directly correlated with the tissue elasticity: the higher the shear wave speed (SWS), the higher tissue stiffness [6][7][8].…”

Point shear wave elastography (pSWE) using Acoustic Radiation Force Impulse (ARFI) imaging: a feasibility study and norm values for renal parenchymal stiffness in healthy children and adolescents

et al. 2017

Aims: To evaluate the applicability of point shear wave elastography (pSWE) for measuring renal parenchymal stiffness in healthy children and adolescents and to establish norm values for shear wave speed (SWS) using two ARFI methods and ultrasound probes.Material and methods: We prospectively investigated 264 children (43.9% males). pSWE (Virtual TouchTM Quantification and Virtual TouchTM Imaging Quantification (VTQ and VTIQ; Siemens, Germany)) was performed in the renal cortex of 528 healthy kidneys using a 1-6 MHz convex and a 4-9 MHz linear ultrasound probe in ventrolateral and dorsal examinations. Feasibility and reproducibility of pSWE measurements were evaluated. SWS values were analysed with regard to age, body dimensions, kidney volume and measuring depth.Results: pSWE measurements were successful in >95% of subjects using the low and in <60% using the high-frequency probe. Mean SWS values (m/s) differed by method and probe: 2.10±0.43 (VTQ1-6MHz, convex, ventrolateral), 2.30±0.37 (VTQ1-6MHz, convex, dorsal), 1.58±0.44 (VTQ4-9MHz, linear, dorsal) and 1.96±0.27 (VTIQ4-9MHz, linear, dorsal). SWS was positively correlated with age, weight and body height, but independent of sex, BMI, or kidney volume and depth.Conclusions: pSWE (VTQ) is a feasible method to evaluate renal parenchymal stiffness in children of all ages. SWS values are age and weight dependent and differ significantly between high- and low-frequency probes. High-frequency probes and VTIQ should only be used in children <10 years.
