目的分析组织谐波成像对胰腺癌血管侵犯的诊断价值。方法对40例胰腺癌患者进行组织谐波和基波超声检查,重点观察胰腺癌对周围血管侵犯情况,对比两组结果。结果在判断胰腺肿瘤对周围大血管的浸润上,组织谐波成像优于普通基波超声成像;另外组织谐波成像对腹腔淋巴结显示更为清晰。结论谐波技术对诊断胰腺癌胰周邻近组织的病变情况很有价值,增加病灶与周围邻近组织的回声差别,有助于判断胰腺癌的可切除性。
Objective To analyze the diagnostic value of tissue harmonic imaging in vascular invasion of pancreatic cancer. Methods Tissue harmonic and fundamental ultrasound were performed in 40 patients with pancreatic cancer. The invasion of peripheral blood vessels by pancreatic cancer was observed. The results of two groups were compared. Results In judging the infiltration of pancreatic neoplasms into the surrounding large vessels, tissue harmonic imaging was superior to ordinary fundamental ultrasound imaging. In addition, tissue harmonic imaging showed more clearly in abdominal lymph nodes. Conclusions Harmonic wave technique is valuable in the diagnosis of pancreatic peripancreatic tissue lesions, and can improve the resectability of pancreatic cancer by increasing the echo difference between the lesion and the adjacent tissues.
