Abstract EN
This study compared the imaging features of conventional gray scale ultrasound (US) before and after contrast-enhanced ultrasound (CEUS) for focal liver lesions and 22 evaluated the role of US post-CEUS in characterizing liver lesions.
126 patients with 158 focal liver lesions underwent CEUS and US post-CEUS examination and entered this study.
There were 74 hepatocellular carcinomas (HCC), 43 hepatic metastases, and 41 hemangiomas.
Imaging features of US pre-CEUS and US post-CEUS were analyzed offsite by two blinded experienced radiologists to evaluate size, boundary, echogenicity, internal texture, posterior acoustic enhancement, spatial resolution, and contrast resolution.
In the end with pathological and clinical evidence, the diagnostic accuracy rate of US pre-CEUS was 53.8% (85/158 lesions), lower than that of CEUS (88.0%, 139/158 lesions); with the complementation of US post-CEUS the rate rose to 93.0% (147/158 lesions).
US post-CEUS could improve the visibility of typical structures of focal liver lesions and might provide important complementary information for CEUS diagnosis.
It also increases the visibility of small liver lesions compared with US pre-CEUS and helps to guide local interventional procedure.
