Objective: To evaluate the diagnostic performance of shear wave elastography in the estimation of fibrosis in patients with chronic liver disease by using biopsy and/or serum markers as reference standard. Materials and methods: 100 patients underwent point quantification-shear wave elastography, for whom noninvasive serum fibrosis indices like APRI, FIB-4, and King’s score were calculated. The receiver-operator characteristic (ROC) curve analysis was performed. Results: The shear wave elastography measurements showed moderate agreement with APRI, FIB-4, and fair agreement with King’s score. The AUROC for differentiating F0-F1, F2-F3, F2-F3, and F4 are 0.873 and 0.504 respectively using APRI as reference standard. The cutoff values derived for differentiating F0-F1 and F2-F3 was 7.07 and for differentiating F2-F3 and F4 was 11.94. Conclusion: The diagnostic performance of shear wave elastography is comparable with that of serum fibrosis indices APRI and FIB-4.
