[摘要] 目的 探讨使用CT诊断肝癌的临床应用效果以及使用的前景。方法 随机选取该院从2010年1月—2015年3月期间诊断治疗过的肝癌患者50例，对其资料进行回顾性分析。结果50例肝癌患者中，经使用CT检查后检出：巨块型肝癌患者30例，在30例巨块型肝癌患者中，肝右叶巨块型肝癌患者24例，肝左叶巨块型肝癌患者4例，尾叶巨块型肝癌患者2例；结节型肝癌25例；弥漫型肝癌5例。所有患者均未检出病灶出血、钙化的情况。增强后边缘常更清楚。 结论 在肝癌的影像学诊断中，螺旋CT是既简单、安全又准确的检查方法。

[Abstract] Objective To investigate the clinical effect of CT applied to the diagnosis of liver cancer and the use prospect. Methods A retrospective analysis was conducted on the data of 50 selected cases with liver cancer diagnosed and treated in our hospital from January 2010 to March 2015. Results By CT detection， of the 50 cases with liver cancer， 30 cases were found with massive hepatocarcinoma， including 24 cases with massive hepatocarcinoma in the right hepatic lobe， 4 cases with massive hepatocarcinoma in the left hepatic lobe， 2 cases with massive hepatocarcinoma in the hepatic caudate lobe； 25 cases were found with nodular hepatocellular carcinoma， 5 cases with diffuse liver cancer. No lesion hemorrhage and calcification were found in all the patients. The lesion edge was often showed more clearly by the enhanced scan. Conclusion Spiral CT scan is a simple， safe and accurate method for the imaging diagnosis of liver cancer.

肝癌对人体有着巨大的伤害。肝癌治疗目前在我国还存在较大的难度。所以，预防和及早发现肝癌就显得异常关键。了解肝癌的有关症状和其他知识，有助于有效预防和及时发现肝癌。怎么样才可以正确的诊断肝癌呢，首先必须到正规的机构进行检查。要确诊肝癌，必须做强化CT检查。正常肝脏由肝动脉和门静脉双重供血，其中肝动脉约占30%，门静脉约占70%。但大多数肝癌的血液供应正好相反，肝动脉提供70%的血液，而门静脉仅提供30%的血液供应[1-3]。CT用于诊断肝癌时，一定要将平扫和强化的CT片对比进行，强化CT利用肝癌的血液供应特点，根据肿瘤所在部位的密度不同和变化进行判断。典型的肝癌CT影像是：平扫区肝癌多为低密度占位，部分有晕圈征；大肝癌常有中央坏死液化。肝癌在动态增强扫描CT下典型的表现为造影剂快进快出，即肿瘤动脉期呈浓染灶，门静脉期造影剂移出较快，平衡期为低密度病灶。……
