Brief Summary:
The purpose of this study is to estimate the clinical value of contrast-enhanced ultrasound in percutaneous biopsy for liver occupied lesion.

Condition or disease Intervention/treatment Phase
Liver Neoplasms Other: CEUS guided biopsy Other: US guided biopsy Device: Ultrasound Not Applicable

Detailed Description:

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.
