Evaluation of Solid Focal Liver Lesions by Shear Wave Sonoelastography with FNAC Correlation

Abstract

Aim: To evaluate the solid focal liver lesions by Shear Wave Sonoelastography (SWE) and correlate Shear Wave Sonoelastography findings with that of FNAC. Methods: 50 patients who were diagnosed to have solid focal liver lesions on sonography during the period August 2017 to September 2019 at JSS Medical College and Hospital, Mysuru underwent Shear Wave Sonoelastography [SWE], following which patient underwent ultrasound guided FNAC for histological evaluation. Results: Benign vs. malignant hepatic lesions could be differentiated using a cut off value of 25 kPa. The overall sensitivity & specificity of SWE was found to be 66% and 30% respectively as a standalone technique, however the predicative accuracy of SWE in conjunction with gray scale sonographic findings was 91.4%. Conclusion: Shear wave elastography can be used as an adjunct in routine sonological practice to evaluate solid focal lesions of the liver. It can help to categorize benign versus malignant lesions.

“…It is exhibited that malignant focal lesions were significantly stiff as compared to benign focal lesions. SWE has a high accuracy rate in distinguishing benign lesions from malignant ones with individual characterization of some malignant lesions like HCC, cholangiocarcinoma, and focal nodular hyperplasia [19] , [20] , [21] . A combination of conventional ultrasound and SWE using parallel testing improved the sensitivity to 100% with a specificity of 75% [22 , 21] .…”

On the arterial phase, these lesions show marginal enhancement and become isodense to liver parenchyma [18] .…”
