|Condition or disease||Intervention/treatment||Phase|
|Liver Neoplasms||Other: CEUS guided biopsy Other: US guided biopsy Device: Ultrasound||Not Applicable|
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:
- Comparison the diagnostic accuracy rate, specificity and sensitivity between CEUS and US group.
- Comparison the diagnostic accuracy rate specificity and sensitivity between smaller(＜3cm) and larger(≥3cm) nodule group.
- To explore operating strategy of contrast-enhanced ultrasound guided biopsy.
- To evaluate economic efficiency of contrast-enhanced ultrasound guided biopsy compared with conventional ultrasound guided biopsy.

|Estimated Study Completion Date :||December 2017|
Experimental: CEUS guided biopsy
Biopsy was operated under contrast-enhanced ultrasound-guided
Other: CEUS guided biopsy
Biopsy was operated under contrast-enhanced ultrasound-guided.
US guided biopsy
Biopsy was operated under conventional ultrasound-guided
Other: US guided biopsy
Biopsy was operated under conventional ultrasound-guided.
- diagnostic accuracy [ Time Frame: 12 months ]diagnostic accuracy=（true positive+ ture negative)/number of parcitipants
