1. Methods Use the quality control way to percutaneous centesis on biopsy breast lump 80 cases under the leading of CT.

2. Methods:Using the color Doppler ultrasound to monitor the centesis of kidney cysts and to orientate the best position in the process of centesis.

3. Biopsy centesis can be performed under the guidance of ultrasonic probe.

4. Methods:To perform the operation of centesis on renal cyst and keep the catheter to fully drainage. Then injection water-free ethanol 3 times into the renal cyst.

5. Objective: To appraise the effect of the improved- centesis using for A-V fistula of the cases needed hemodialysis.

6. Methods:Translumbar(transsacral) centesis and continuous epidural block with 1%lidocaine were performed.

7. Objective To probe into the clinical efficacy of centesis guided by ultrasound in diagnosis and treatment of abdominal abscess.

8. Conclusions:The color doppler should be the first choice in the centesis of kidney cysts.

9. Purpose:To discuss the clinical application and maneuver of CT-guided percutaneous centesis .

10. Methods 104 patients were involved in our study, we treat aneurysms with different intravascular therapy techniques,[Sentencedict] anti-artery-spasm treatment and lumber centesis were performed after therapy.

11. Objective:To discuss the status , indication and operation methods through skin-lungs centesis in the treatment of cavernous pulmonary tuberculosis .

12. Results:The color Doppler is much better than the dimensional ultrasound B in the centesis of kidney cysts.

13. Objective : To assess the usage of color doppler monitoring method in the centesis of kidney cysts.

14. Objective To sum up the experience of the quality control that centesis biopsy on the breast focus under the leading of CT.
