目的：探讨64层螺旋CT多期增强扫描在肝脏占位性病变诊断和鉴别诊断中的应用价值。方法将在我科进行的56例(72处病灶)肝脏占位性病变患者作为研究对象，将其根据诊治先后分为对照组与观察组，每组28例。对照组给予CT平扫，观察组给予CT平扫加多期增强扫描，以病理检查结果为金标准，对比分析两组患者临床诊断正确率。结果对照组CT平扫的检出率为50.0%，与病理检查结果相比，存在显著差异(P＜0.05)；观察组CT多期增强扫描检出率为92.9%，与病理诊断结果相比，无显著差异(P＞0.05)；观察组诊断准确率明显高于对照组，差异显著(P＜0.05)。结论螺旋CT多期增强扫描在肝脏占位性病变中的诊断价值较高，可显著提高临床诊断率，避免病灶误诊的发生，对肿瘤具有增强信息的作用，可为临床诊治提供重要的参考依据。

Objective To investigate the application value of CT multi-phase enhance scanning in diagnosis and identification of liver space-occupying lesions.Methods Fifty six patients (72 lesions) with liver space-occupying lesions admitted the Radiology Department of the Hospital were selected as research subjects, who were divided into the control group and the observation group with 28 cases in each group according to the sequence of diagnosis and treatment. Patients in the control group were subject to CT scan, and patients in the observation group were subject to multiphase dynamic CT scan, pathological examination results were treated as gold standards, and clinical diagnostic accuracy of patients in two groups were compared and analyzed.Results The positive rate of CT scan was 50.0%, and there was significant difference when compared to pathologic examination results (P<0.05). The positive rate of CT multi-phase enhance scanning of patients in the observation group was 92.9%, and there was no significant difference when compared to pathological diagnosis (P>0.05). The diagnostic accuracy of patients in the observation group was obviously higher than that of patients in the control group, and the difference was significant (P<0.05).Conclusion CT multi-phase enhance scan delivers high diagnosis value on liver space-occupying lesions, it can significantly improve clinical diagnostic rate, avoid the occurrence of lesion misdiagnosed, and impose enhanced role of information, be qualified for providing important reference basis for clinical diagnosis and treatment.
