目的 探讨CT平扫与增强扫描在 肝衰竭分期诊断中的应用价值。方法 回 顾性分析我院2014年1月-2016年1月期间 接收诊治的47例肝衰竭患者的临床资料和 CT平扫与增强扫描影像学资料。结果 47 例肝衰竭患者中急性肝衰竭6例、亚急性 肝衰竭12例、慢加急性肝衰竭14例和慢性 肝衰竭11例。CT影像特征上早期肝衰竭表 现为大块状融合病灶有42例，中期肝衰竭 显示为弥漫性多发结节状病灶有16例，晚 期肝衰竭患者表现为多发小片状病灶有7 例。结论 CT平扫与增强扫描对肝衰竭是 一种安全、便捷且可信的术前检查方法， 可以有效减少其它检查方式带来的潜在危 害。此外根据CT平扫与增强扫描影像学表 现可以较准确的确定肝衰竭的类型以及时 期，经病理学确定，CT诊断肝衰竭及分期 结果正确率很高，值得临床进一步推广和 应用。

Objective To investigate the value of CT combined with enhanced scan in the stage diagnosis of liver failure. Methods Retrospectively analyze CT angiography data and clinical data of 47 patients from January 2014 to January 2016. Results Among 47 patients, there are 6 cases of acute liver failure, 12 cases of sub-acute liver failure, 14 cases of acute on chronic liver failure and 11 cases of chronic liver failure. There are 42 cases with large block fusion lesions on CT imaging during the early stage of liver failure, 16 cases with multiple nodular lesions on CT imaging during the middle stage of liver failure, and 7cases with small plaque lesions during the late stage of liver failure. Conclusion CT combined with enhanced scan is a safe, convenient and trusted preoperative examination method which can effectively reduce the potential harm caused by other inspection methods. Besides, it can effectively diagnose the type and stage of liver failure, according to pathological diagnosis, CT diagnosis accuracy rate of is up to 100%, which is worthy of further spread and application.
