目的探讨实质性脏器内血管结构的三维超声重建方法及其临床应用前景。方法对１０例正常肝脏和９例异常肝脏的肝内血管进行三维超声重建，所用仪器为韩国Ｍｅｄｉｓｏｎ公司的ＫｒｅｔｚＶｏｌｕｓｏｎ５３０Ｄ三维超声成像系统，探头为三维容积探头，频率３．５～５．０ＭＨｚ。重建模式选用透明成像最小回声模式、表面成像模式及混合模式。结果用透明成像最小回声模式重建的肝内血管三维图像，其血管树连续性好，无中断现象；可显示末端细小的分支或属支；血管形态规整，边缘平滑；血管间空间关系明确；能整体显示肝内大血管，类似其真实解剖关系。透明成像模式与其它成像模式如与Ｘ线模式或表面模式组合，能同时识别肝内血管结构与周围病变组织的空间毗邻关系。用表面成像模式重建的血管三维图像，可清晰显示血管的内腔及其内壁结构特征，并可显示血管分叉处的开口。结论肝内血管的三维重建将对肝内血管性疾病的诊断及制定治疗方案提供更为丰富的信息 Objective To explore the method of three-dimensional reconstruction of blood vessels in a parenchyma and its clinical application. Methods Three-dimensional echocardiography was performed in 10 cases of normal liver and 9 cases of abnormal liver. The instrument used was KretzVoluson530D three-dimensional ultrasound imaging system from Medison Company in Korea. The probe was a three-dimensional volume probe with a frequency of 3.5-5.0 MHz. Reconstruction mode selection of transparent imaging minimum echo mode, surface imaging mode and mixed mode. Results The three-dimensional images of intrahepatic vessels reconstructed with the minimal echo mode of transparent imaging showed good vascular continuity and no interruption. They could show the small branches or branches at the terminal end. The vessels were regular in shape and the edges were smooth. The spatial relationship between the vessels was clear. The overall display of intrahepatic blood vessels, similar to its true anatomy. The combination of transparent imaging modalities with other imaging modalities, such as with X-ray or surface modalities, simultaneously identifies the spatial proximity of intrahepatic vascular structures to surrounding diseased tissue. The three-dimensional image of the blood vessel reconstructed with the surface imaging mode clearly shows the structural features of the lumen and its inner wall of the blood vessel and can display the opening of the blood vessel bifurcation. Conclusion The three-dimensional reconstruction of intrahepatic vessels will provide more information on the diagnosis and treatment of intrahepatic vascular diseases
