Liver Elastography

Abstract Purpose Liver elastography is increasingly being applied in screening for and follow-up of pediatric liver disease, and has been shown to correlate well with fibrosis staging through liver biopsy. Because time is of the essence when examining children, we wanted to evaluate if a reliable result can be achieved with fewer acquisitions. Materials and Methods 243 healthy children aged 4–17 years were examined after three hours of fasting. Participants were divided into four age groups: 4–7 years; 8–11 years; 12–14 years and 15–17 years. Both two-dimensional shear wave elastography (2D-SWE; GE Logiq E9) and point shear wave elastography (pSWE; Samsung RS80A with Prestige) were performed in all participants, while transient elastography (TE, Fibroscan) was performed in a subset of 87 children aged 8–17 years. Median liver stiffness measurement (LSM) values of 3, 4, 5, 6, 7, and 8 acquisitions were compared with the median value of 10 acquisitions (reference standard). Comparison was performed for all participants together as well as within every specific age group. We investigated both the intraclass correlation coefficient (ICC) with absolute agreement and all outliers more than 10 %, 20 % or ≥ 0.5 or 1.0 kPa from the median of 10 acquisitions. Results For all three systems there was no significant difference between three and ten acquisitions, with ICCs ≥ 0.97. All systems needed 4 acquisitions to achieve no LSM deviating ≥ 1.0 kPa of a median of ten. To achieve no LSM deviating ≥ 20 % of a median of ten acquisitions, pSWE and TE needed 4 acquisitions, while 2D-SWE required 6 acquisitions. Conclusion Our results contradict recommendations of 10 acquisitions for pSWE and TE and only 3 for 2D-SWE.

Aim: To evaluate the performance of 2D shear-wave elastography from General Electric (2D-SWE.GE) for the noninvasiveassessment of liver fibrosis and to identify liver stiffness (LS) cut-off values for predicting different stages of fibrosisusing Transient Elastography (TE) as the reference method. Material and method: We included 331 consecutive subjectswith or without chronic hepatopathies in whom LS was evaluated in the same session by means of 2 elastographic techniques:TE and 2D-SWE.GE. Reliable LS measurements were defined for TE as the median value of 10 measurements with a successrate of ≥60% and an interquartile range (IQR)<30% and for 2D-SWE.GE as the median value of 10 measurements acquiredin a homogenous area and an IQR<30%. To discriminate between TE fibrosis stages we used the following cut-offs: F2- 7;F3- 9.5 and F4- 12kPa. Results: Reliable LS measurements were obtained in 95.8% subjects by 2D-SWE.GE, and 94.2%by TE (p=0.44). Based on TE cut-off values we divided our cohort into four groups: F<2: 30.1%; F=2: 10.2%; F=3: 12.2%;F=4: 47.5%. A strong correlation was found between the LS values obtained by the 2 methods: r=0.83, p<0.0001.LS valuesobtained by 2D-SWE.GE were significantly lower than those obtained by TE: 10.14±4.24 kPa vs. 16.72±13.4 kPa (p<0.0001).The best cut-off value for F≥2, F≥3 and for F=4 were 6.7, 8.2 and 9.3 kPa. Conclusions: The best 2D-SWE.GE cut-off valuesfor predicting F≥2, F≥3 and F=4 were 6.7, 8.2 and 9.3kPa.

Background: The aim of this study was to evaluate the usefulness of two different types of 2-dimensional shear wave elastography (2D-SWE) for predicting liver fibrosis stages in comparison to transient elastography (TE), using a histologic METAVIR scoring system as the reference method. Methods: A total of 203 patients with chronic liver disease were prospectively enrolled in the study. Two different 2D-SWEs (LOGIQ S8 and E9 systems, GE Healthcare, Chalfont St Giles, UK) were assessed for liver stiffness in patients with chronic liver diseases. Patients received 2D-SWE examinations with the S8 and E9 systems, and also underwent TE (FibroScan®, Echosens, France) tests and liver biopsies on the same day. Results: The most common etiology of chronic liver disease was non-alcoholic fatty liver disease (28.7%), followed by chronic hepatitis B (25.1%). Liver fibrosis stages consisted of F0 (22.6%), F1 (29.7%), F2 (16.9%), F3 (12.8%) and F4 (17.9%). Overall, S8 and E9 were well correlated with the histologic fibrosis stages. The optimal cut-off values for S8 and E9 to differentiate significant fibrosis (≥F2) were 6.70 kPa and 6.42 kPa, respectively, while the cut-off values for S8 and E9 in distinguishing liver cirrhosis were 9.15 kPa and 8.88 kPa, respectively. Among the 195 patients who had successful measurements in both S8 and E9, liver stiffness showed good inter-equipment correlation (ICC: 0.900, p < 0.001). Regarding diagnostic ability, upon comparison (FibroScan®), there were no significant differences between 2D-SWEs and TE for detecting every stage of liver fibrosis. Conclusion: In comparison to TE, 2D-SWE with LOGIQ S8 and E9 (GE Healthcare) are useful non-invasive tools for predicting significant fibrosis and liver cirrhosis.

Aims: To prospectively assess the cutoff values of a point shear wave measurement (SWM) method for ruling-in and ruling-out significant fibrosis and cirrhosis using transient elastography (TE) as the reference standard.Method: Consecutive patients with chronic hepatitis C were enrolled. Liver stiffness was assessed with the SWM method implemented on the HI VISION Ascendus ultrasound system (Hitachi Ltd, Japan) and with the TE method of the FibroScan® device (Echosens, France). For staging significant fibrosis (F≥2) and cirrhosis (F=4) we used the TE cutoffs of 7.0 and 12.0 kiloPascal (kPa), respectively. The diagnostic performance of SWM was assessed by calculating the area under the receiver operating characteristic (AUROC) curve. Cutoffs with specificity or sensitivity > 90% were chosen to rule-in or rule-out F≥2 and F=4.Results: 445 individuals [235 males, 210 females; mean age, 61.1 (13.3) years] were studied: 190 (42.7%) individuals had F0-F1 fibrosis stage, 82 (18.4%) F2, 46 (10.3%) F3, and 127 (28.6%) F4 fibrosis stage. For ruling-in F≥2 the SWM cutoff was 6.78 kPa [sensitivity, 76.9%(70.6-82.4); specificity, 90.3% (85.0-94.3)] and for ruling-out it was 5.55 kPa [sensitivity, 90.6% (85.8-94.1); specificity, 72.2% (64.9-78.6)]. For ruling-in F=4 the SWM cutoff was 9.15 kPa [sensitivity, 83.3% (74.4-90.2); specificity, 90.1% (86.0-93.2)] and for ruling-out it was 8.41 kPa [sensitivity, 90.6% (82.9-95.6); specificity, 82.2% (77.3-86.4)]. AUROCs were 0.92 (0.89-0.94) for F≥2 and 0.94 (0.91-0.96) for F=4.Conclusions. In clinical practice, the use of a dual cutoff of SWM may increase the confidence in staging liver fibrosis with a non-invasive shear wave elastography technique.Abbreviations: ARFI: acoustic radiation force impulse; AUROC: area under the ROC curve; CCC: concordance correlation coefficient; IQR/M: interquartile range/median; LSM: liver stiffness measurement; ROC: receiver operating characteristic; pSWE: point shear wave elastography; SWM: shear wave measurement; TE: transient elastography; US: ultrasound.

Non Invasive

In recent years, several non-invasive methods have been developed for staging liver fibrosis in patients with chronic hepatitis C. A 2D-Shear wave elastography (SWE) technique has been recently introduced on the EPIQ 7 US system (ElastQ), but its accuracy has not been validated in patients with chronic hepatitis C virus (HCV) infection. We enrolled 178 HCV patients to assess their liver fibrosis stage with ElastQ software using transient elastography as a reference standard. The best cut-off values to diagnose ≥ F2, ≥ F3, and F4 were 8.15, 10.31, and 12.65 KPa, respectively. Liver stiffness values had a positive correlation with transient elastography (r = 0.57; p < 0.001). The area under the receiver operating characteristics (AUROC) was 0.899 for ≥ F2 (moderate fibrosis), 0.900 for ≥ F3 (severe fibrosis), and 0.899 for cirrhosis. 2D-SWE has excellent accuracy in assessing liver fibrosis in patients with chronic hepatitis C and an excellent correlation with transient elastography.
