Abstract
The goal of this study was to see if automatic biopsy guided by ultrasound could be used to provide a qualitative diagnosis of a liver tumor. Methods. A total of 40 patients (101 focuses) were treated with automatic liver parenchyma biopsy under ultrasound guidance, and the correlation between pathological outcomes and ultrasound images was investigated. The lesion size in the observation group was compared to that in the control group using conventional ultrasound (P > 0.05), and there was no significant difference. Under contrast-enhanced ultrasound (CEUS), there was no statistically significant difference in lesion size between the observation and control groups (P > 0.05). The difference in lesion size between the conventional ultrasonography and CEUS observation groups was statistically significant (P 0.05). Conclusion. Ultrasound-guided automated biopsy of the liver parenchyma is a simple and effective procedure with fewer problems and a high diagnostic rate, and it deserves to be promoted clinically.
Highlights
In recent years, ultrasound-guided automated biopsy has become widely used in qualitative diagnosis of abdominal and pelvic space-occupying focus. e mortality rate of liver cancer has been rising in European and American countries in recent years
Among the 81 cases with 110 focuses that underwent contrast-enhanced ultrasound (CEUS) before radio frequency activation (RFA), and 86 cases with 112 focuses that did not undergo CUES before RFA, the results showed that seven new focuses were found during CEUS examination, which were not found in conventional ultrasound examination or enhanced CT examination
[12] A retrospective study was conducted to analyze 64 ablation cases. e subgroups in this study found that the residual tumor rate in the CEUS group at the end of treatment was 0%, while the residual tumor rate in the nonCEUS group was 16.7%. e results showed that performing CEUS immediately at the end of RFA treatment to evaluate the ablation effect could effectively reduce the incidence of residual tumors after thermal ablation, and provide accurate information for RFA operators to guide ablation treatment

Ultrasound-guided automated biopsy has become widely used in qualitative diagnosis of abdominal and pelvic space-occupying focus. E mortality rate of liver cancer has been rising in European and American countries in recent years. Hepatic hemangioma is a frequent benign liver tumor caused by a congenital blood vessel abnormality. E bulk of them are cavernous hemangiomas of the liver, and the last three are uncommon in clinic. Cavernous hemangioma is the most common type of hepatic hemangioma seen in clinic. Hemangioma is more frequent in the liver than in other organs. Liver cancer and liver hemangioma are two distinct diseases with distinct occurrences, progressions, treatments, and prognoses. In clinical work, determining the nature of focused focus detected in liver tests is quite useful in guiding treatment
