摘要
目的:探讨肝癌在动脉三期的强化特点及临床应用价值。方法:肝癌27例,分别行动脉三期扫描,动脉早期、中期和晚期的扫描时间是在注射造影剂后的18s、24s、30s。结果:动脉早期无强化13例,强化14例,其中血管样强化9例,肿瘤实质样强化5例。动脉中期无强化3例,强化24例,其中血管样强化16例,肿瘤实质样强化8例。动脉晚期均有不同程度强化,其中血管样强化4例,肿瘤实质样强化23例。结论:动脉三期均能很好反应肝癌的强化特点,动脉中期肿瘤血管显影较佳,动脉晚期肿瘤整体强化较佳。
Objective： To discuss hepatocellular carcinoma enhancement characteristic and value of clinical application of arterial triple phase enhancement. Methods： Twenty-seven patients with hepatocellular carcinoma who had diagnosed clearly, they were all scanned by early arterial, middle arterial and late arterial phase, scanning time was 18s （early arterial）, 24s（middle arterial）, 30s （late arterial） after the contrast agent was injected. Results： Fourteen cases of hepatocellular carcinoma were enhancement and 13 cases of hepatocellular carcinoma were not enhanced in early arterial phase; which 9 cases had blood vessel-like enhancement and 5 cases had whole tumor parenchymal enhancement. Twenty-four cases of hepatocellular carcinoma had enhancement and 3 cases of hepatocellular carcinoma had no enhancement in middle arterial phase, which 16 cases had blood vessel-like enhancement and 8 cases had whole tumor of parenchymal enhancement. All cases were enhanced in late arterial phase with different degree which 4 cases had blood vessel-like enhancement and 23 cases had whole tumor parenchymal enhancement. Conclusion： Triple arterial phase enhancement can reflect enhancement characteristic of hepatocellular carcinoma, tumor vessels are well enhanced in middle arterial phase and whole tumor enhancement is good in late arterial phase.
