The study evaluated the effectiveness of two ultrasound techniques, point shear-wave elastography (p-SWE) and 2D-shear-wave elastography (2D-SWE), for staging liver fibrosis, using transient elastography (TE) as a benchmark.
Results showed that both p-SWE and 2D-SWE correlated well with TE results, but p-SWE demonstrated higher accuracy, especially for identifying advanced fibrosis stages.
The optimal cutoff values for diagnosing significant fibrosis were found to be very similar for both techniques, but p-SWE had better sensitivity and specificity compared to 2D-SWE.
