三维超声不同成像模式在肝脏占位诊断中的应用研究

目的筛选检测肝脏占位性病变的最佳三维成像模式，明确三维超声对肝脏占位性病变的诊断价值。方法对48个肝脏占位性病变应用不同的三维成像模式（表面纹理模式、表面平滑模式、梯度增强模式、最小回声模式、最大回声模式、X线模式）成像，对各成像模式的图像质量评分，计算重建成功率，并与二维声像图比较。结果各种成像模式中，表面纹理模式得分较其它模式高，重建成功例数较表面平滑模式、最小回声模式、最大回声模式及X线模式的例数多，差异均有统计学意义（P〈0．05）。48个病灶中，三维超声确诊40个，二维超声确诊28个，二者差异有统计学意义（P〈0．05）。结论在肝脏占位三维成像模式中，表面纹理模式比较理想，能够提高肝脏占位性病变的诊断率。

The application study of liver lesions by different three-dimensional ultrasound imaging mode

Objective To investigate the best three - dimensional ultrasound imaging mode of liver lesions, and to explore the value of three - dimensional ultrasound in the diagnosis of liver lesions. Methods Forty - eight liver lesions were reconstructed by different three- dimensional ultrasound imaging modes （Surface texture mode, Surface smooth mode, Gradient enhancement mode, Minimns echo mode, Maximum echo mode, X - ray mode ）. Then scored the picture quality of these images, calculated the reconstructed achievement ratio, and the results were compared with two-dimensional ultrasound images. Results In these images modes, the surface texture model got the higher score and achievement ratio. There was significant differences among different imaging modes（ P 〈 0.05）. In 48 liver lesions, 40 of them were confirmed by three - dimensional ultrasound, 28 of them were confirmed by two - dimensional ultrasound, there was significant difference between two groups（ P 〈 0.05）. Conclusion The surface texture three - dimensional ultrasound imaging mode is an ideal mode of liver lesions, it can improve the diagnostic accuracy of liver lesions.
