目的⑶以彩色多普勒血流显像分析了 ７５ 例原发性肝癌 ⒉１ ０５ 个病灶⒕和 ５ ４ 例肝转移癌 ⒉９６ 个病灶⒕的血供类型⒙旨在提供诊断和鉴别诊断的依据⒚方法⑶用彩色多普勒血流频谱对肝固有动脉、门静脉和肿瘤的供养血管的血流动力学参数进行测定⒙所用指标为最大血流速度 ⒉ Ｖｍ ａｘ⒕⒛阻力指数 ⒉ Ｒ Ｉ⒕⒛搏动指数 ⒉ Ｐ Ｉ⒕⒛最大与最小血流速度之比 ⒉ Ａ ／ Ｂ⒕和血流量 ⒉ Ｆ Ｖ ⒕⒚结果⑶原发性肝癌和肝转移癌的肝固有动脉和门静脉的 Ｖｍ ａｘ 和 Ｆ Ｖ 均高于正常对照组 ⒉ Ｐ＜ ００ ０１⒕⒙而肝固有动脉的 Ｒ Ｉ、 Ｐ Ｉ、 Ａ／ Ｂ 值均低于对照组⒚原发性肝癌组中 ８２ 个病灶可见搏动性血流信号 ⒉９ １１％ ⒕⒙其中 ６５ 个为 ⒈篮网⒔状 ⒉７２２％ ⒕⒚肝转移癌主要表现为瘤周供血⒚结论⑶彩色多普勒血流显像有助于提高原发性肝癌和肝转移癌的诊断和鉴别诊断精度⒙但对于多血管性肝转移癌的鉴别是不可靠的⒚
Objectives (3) To analyze the blood supply types of 2.1 cases of primary liver cancer (2.105) and of 54 cases of liver metastases (2.96 lesions) by color Doppler flow imaging. 18. To provide basis for diagnosis and differential diagnosis. 19. Methods (3) Hemodynamic parameters of hepatic artery, portal vein, and tumor vascularity were measured by color Doppler flow spectroscopy. 18. The index used was the maximum blood flow velocity 2. Vm ax 14.20. Resistance index 2. R I14.20. Pulsation index 2. P I14.20. The ratio between the maximum and minimum blood flow velocity was 2. A/B14. and blood flow was 2. F V 14.19. Results (3) Vm ax and F V were higher in the hepatic artery and portal vein of primary liver cancer and liver metastases than in the normal control group. 0 0 0114.18. However, the values of R I, P I, and A/B in the proper hepatic artery were lower than those in the control group. 19. The pulsatile blood flow signal in 82 lesions in the primary liver cancer group was 2.9 1 1% 14.18. Of these, 65 were 1. Nets 13. Shaped 2.72 2% 14.19. Liver Metastasis Carcinoma Mainly Peri-tumoral Blood Supply 19. Conclusion (3) Multi-color Le Flow Imaging helps improve the accuracy of diagnosis and differential diagnosis of primary liver cancer and liver cancer ⒙ but for multi-vascular liver cancer identification is not reliable ⒚
