目的探讨多期增强CT在小肝癌的诊断价值。方法 2010年7月至2012年7月期间,我院诊治的35例小肝癌患者,全部进行16层螺旋CT多期增强扫描,对其影像学资料进行回顾性分析。结果 35例小肝癌患者,共检出46个病灶,动脉期、门脉期以及延迟期的检出率分别为97.8%(45/46)、82.6%(38/46),以及87.0%(40/46)。多期增强CT扫描显示,动脉期以高密度灶为主、门脉期以低密度灶为主、延迟期以低密度灶为主,肿瘤病灶的密度形成了“高密度-低密度”或者“低密度-低密度”的变化模式。结论多期增强CT扫描,能够清晰显示肝癌病灶的强化特点,较为准确地评估肝癌的血供特点,指导临床医师选择合适的治疗方案。
Objective To investigate the diagnostic value of multi-phase enhanced CT in small hepatocellular carcinoma. Methods From July 2010 to July 2012, 35 patients with small hepatocellular carcinoma who were diagnosed and treated in our hospital underwent multi-phase contrast-enhanced 16-slice spiral CT scans. Their imaging data were retrospectively analyzed. Results Of the 35 patients with small hepatocellular carcinoma, 46 lesions were detected. The detection rates were 97.8% (45/46), 82.6% (38/46), and 87.0% (40) of arterial, portal, and delayed periods, respectively. /46). Multi-phase contrast-enhanced CT scans showed that high-density foci dominated the arterial phase, low-density foci in the portal phase, and low-density foci in the delayed phase. The density of the tumor lesions formed a “high-density-low-density” Or “low density - low density ” change mode. Conclusion The multi-phase enhanced CT scan can clearly show the enhanced characteristics of liver cancer lesions, more accurately assess the characteristics of hepatic cancer blood supply, and guide clinicians to choose the appropriate treatment plan.
