摘要
目的探讨动态三维超声造影(3D-CEUS)显示动脉相肝癌血管增强方式及特点的应用价值。方法选取33例肝癌患者,均行常规超声、二维超声造影(2D-CEUS)及动态3D-CEUS检查,观察并比较2D-CEUS和动态3D-CEUS的病灶增强方式、动态灌注过程及肿瘤血管的空间分布情况。结果 2D-CEUS与动态3D-CEUS在肝癌造影增强时相和增强方式方面表现相同,其中30例原发性肝癌动脉相增强方式均表现为快进快出,3例转移性肝癌表现分别为动脉相快速整体增强、不均匀增强及环状增强。动态3D-CEUS在显示肝癌血管起源、分布及数目方面均明显优于2D-CEUS,差异均有统计学意义(均P<0.05)。结论动态3D-CEUS能更直观地显示肝癌血管的空间立体关系,以及病灶周边及内部血管的分布方式,具有较好的临床应用价值。
Objective To investigate the application value of dynamic three-dimensional contrast-enhanced ultrasound(3D-CEUS)in displaying vascular patterns of hepatic cancer in the arterial phase.Methods Totally 33 hepatic cancer were examined by contrast-enhanced ultrasound(2D-CEUS)and dynamic 3D-CEUS,the enhancement patterns,dynamic perfusion process and spatial distribution of tumor vessels were compared and analyzed.Results Thirty cases of hepatic cancers showed enhanced fast-in,3 cases of metastatic liver cancer showed different manifestations,which were arterial phase rapid whole enhancement,uneven and ring enhancement.In the enhancement pattern,dynamic 3D-CEUS was similar to 2D-CEUS.However,dynamic 3D-CEUS was superior to 2D-CEUS in the display of spatial relationships of hepatic tumor and vascularity(all P<0.05).Conclusion Dynamic 3D-CEUS can display the spatial relationship of hepatic tumors and vascularity more visuaIly,which has better clinical application value.
