The value of pancture biopsy on liver tumor guided by multimodal ultrasound
Objective To explore the impact of multimodal ultrasound on the success rate of liver tumor puncture biopsy.Methods A retrospective analysis was conducted on the clinical and imaging data of 429 patients who underwent liver tumor puncture from September 2018 to August 2021.According to whether multimodal ultrasound had an impact on the puncture plan of the lesion,patients were divided into a conventional ultrasound group(n=244,the puncture plan was not affected)and multimodal ultrasound group(n=189,the puncture plan was influenced by multimodal ultrasound).The accuracy of puncture biopsy was compared between the two groups by analyzing the characteristics of lesion diameter,boundary,and echo.Results All 433 lesions could be displayed under different ultrasound modes.The accuracy of conventional ultrasound guided biopsy was 92.6%(226/244)for 244 lesions in the conventional ultrasound group,and 91.0%(172/189)for 189 lesions in the multimodal ultrasound group after multimodal ultrasound evaluation.There was no statistically significant difference between the two groups(P=0.540).Out of 433 lesions,376(86.8%)were malignant and 22(5.1%)were benign.The false negative rate in the conventional ultrasound group was 7.4%(18/244),while in the multimodal ultrasound group it was 9.0%(17/189).The main complications in this group were mild pain and minor bleeding.Conclusion Multimodal ultrasound can improve the lesion display rate,thus improving the biopsy accuracy for lesions displayed poorly on conventional ultrasound or with difficulty in puncturing.
