摘　　要：目的 探讨二次谐波技术对胰腺肿块的诊断价值。方法 对47例患者和30例正常胰腺者比较基波与谐波条件下二维及彩色血流特点。结果 谐波条件下不同类型胰腺肿块的二维特征性更加清晰,正常胰腺和肿块周围及内部的血流可得到不同显示。结论 谐波技术对受气体干扰明显、位置较深的胰腺肿块的超声检出和鉴别诊断有重要临床意义。Objective To discuss the value of second harmonic imaging in diagnosing pancreatic masses. Methods Forty-seven cases with pancreatic masses and thirty controls were examined with conventional ultrasonography and second harmonic imaging. Characteristics of gray scale uhrasonography, colour Dopper flow imaging and second harmonic imaging were compared. Results On second harmonic imaging, different pancreatic masses presented clearer than those on conventional ultrasonography, and color flow signals in and around the pancreatic masses were shown more than those on conventional ukrasonography. Conclusion It is of clinical value for second harmonic imaging in detecting and diagnosing deeply-located pancreatic masses which is interfered easily by gastric gases.
