The Multi-center Study of Percutaneous Focal Liver Lesions Biopsy Guided by Contrast-Enhanced Ultrasound
The purpose of this study is to estimate the clinical value of contrast-enhanced ultrasound in percutaneous biopsy for liver occupied lesion.
The patients with liver neoplasms who need receive percutaneous biopsy were randomized into contrast-enhanced ultrasound(CEUS) group and conventional ultrasound(US) group.The aims include: 1. Comparison the diagnostic accuracy rate, specificity and sensitivity between CEUS and US group. 2. Comparison the diagnostic accuracy rate specificity and sensitivity between smaller(\<3cm) and larger(≥3cm) nodule group. 3. To explore operating strategy of contrast-enhanced ultrasound guided biopsy. 4. To evaluate economic efficiency of contrast-enhanced ultrasound guided biopsy compared with conventional ultrasound guided biopsy.
