3D(4D)超声成像技术在肝肾囊肿介入穿刺中的临床应用

Value of 3D(4D) ultrasound guidance in the liver and kidney cyst punctures

目的评价3D(4D)超声成像技术在肝肾囊肿介入穿刺中的临床应用价值。方法分别用动态三维成像(即4D超声成像)、实时动态三维成像(即实时4D冠状面成像)和静态三维成像的条件进行肝肾囊肿的引导穿刺过程。结果①4D超声成像无法达到实时状态,显示的图像落后于针道的步进,图像平均采集时间较长。实时动态4D冠状面成像,引导穿刺过程效果最佳,能达到实时状态;②穿刺针在4D冠状面图像和融合平面上比正常情况要厚一些,这一现象增加了针在穿刺过程中的可视性;③静态3D只能穿刺结束后评价针的最终位置而不能引导穿刺的过程;④实时4D的最佳成像模式为表面质地模式50%和透明最大模式50%混合,动态4D以多平面成像和表面模式成像引导穿刺过程为最佳。结论3D(4D)超声成像技术为超声引导穿刺过程开辟了一条新的途径。

Objective To evaluate the value of 3D （4D） ultrasound guidance in the liver and kidney cyst punctures. Methods Respectively applied dynamic three dimensional imaging （4D）, real time three dimensional imaging（real time 4D） and static three dimensional imaging on the process of the liver and kidney cyst interventional puncture. Results ①4D ultrasound could not attain the real time condition. The image fell behind to the movement of the needle. The collect time of the image was longer than the real time 4D ultrasound. The effect of the real time 4D was optimal. It could attain real time condition; ②The puncture needle was thicker on the image of the real time 4D than the image of the mixture plane. This appearance increased vision effect; ③Static state 3D could evaluate the ultimate place of needle and could not guide the puncture process; ④The optimal pattern of real time 4D was the superficial pattern 50% and the most largest transparent pattern 50% blend. Conclusion 3D （4D） ultrasound technique hews out a new road in guiding the puncture process.
