四维超声成像技术在肝肾囊肿介入穿刺术中的应用价值

摘要

ObjectiveTo explore the effectiveness of application of four-dimensional ultrasound imaging technology in the liver and kidney cyst puncture.Methods Altogether 27 patients with hepatic and renal cysts were selected as the research object and evenly divided into three groups. And the static three-dimensional (3D) imaging, dynamic three-dimensional (4D) imaging, real-time dynamic three-dimensional (real-time 4D) imaging technologies were applied in puncture-oriented processes respectively for three groups.Results The 3D ultrasound imaging only could display the post-puncture ifxed position of the needle but could not show the entire puncture process. 4D ultrasound imaging showed disadvantages in poor real-time imaging, delayed displaying and long acquisition time. Real-time 4D ultrasound imaging could realize real-time transmission of the puncture procedure. The combination of 50% largest transparent model and 50% surface texture as well as the combination of surface imaging mode, multi-planar imaging and image-guided puncture resulted in the best imaging quality.Conclusion 4D ultrasound imaging technology proved its effectiveness in the liver and kidney cyst puncture, especially the real-time dynamic imaging technology, which was worth of widespread use.%目的：探讨四维超声成像技术在肝肾囊肿介入穿刺术中的应用价值。方法选取27例肝肾囊肿患者，随机分为3组（每组9人）。分别采用静态三维成像、动态三维成像、实时动态三维成像3种技术进行穿刺引导，比较3种成像技术的效果。结果静态三维成像无法显示整个穿刺过程，只显示穿刺后穿刺针的固定位置；动态三维成像实时性差，成像较进针存在延迟，采集时间长；实时动态三维成像能实时传输穿刺过程，50%透明最大与50%表面质地模式结合、表面成像与多平面成像结合引导穿刺成像效果最佳。结论四维超声成像技术在肝肾囊肿介入穿刺术中效果良好，其中以实时动态三维成像技术效果最佳，值得临床广泛使用。
