Abstract
To determine the elasticity characteristics of focal liver lesions (FLLs) by shearwave elastography (SWE). We used SWE in 26 patients with 30 FLLs for quantitative FLLs stiffness assessment. For each lesion, stiffness was measured in (kPa).Characterization of the lesion relied on triphasic CT, or biopsy. Data were coded and entered using the statistical package SPSS version 22. SWE acquisitions failed in 5 nodules (17%) in 5 patients. For the 25 lesions successfully evaluated, There is significant difference in stiffness between malignant and benign groups with (P < 0.001), SWE values were (in kPa), for the 9 HCCs (20.67 ± 5.22), for the 9 metastatic lesions was (35.89 ± 12.55), for the 4 Haemangiomas (7.50 ± 2.38), for the two focal fatty infiltration (8.50 ± 0.71 kPa), for one hepatic abscess (7 ± 2 kPa). SWE, as an adjunct to conventional ultrasound, provides additional information for the characterization of focal liver lesions based on the tissue elasticity values
