螺旋CT在小肝癌与肝小血管瘤中的鉴别诊断意义

目的：探讨螺旋CT在小肝癌与肝小血管瘤的鉴别诊断的临床意义。方法：对小肝癌患者与肝小血管瘤患者的CT特点进行总结,分析各自的CT特点。结果：小肝癌平扫发现病灶31个,27/34为低密度,4/34为高密度;肝小血管瘤平扫发现病灶27个,24/32为低密度,3/32为高密度;小肝癌增强扫描门脉期以及延迟期的低密度病灶明显多于动脉期（P〈0.05）,且多于肝小血管瘤的门脉期和延迟期（P〈0.05）。结论：根据CT平扫和增强扫描的不同特点,对于区别小肝癌和肝小血管瘤有一定的诊断价值,值得临床重视。

Diagnosis of spiral CT in small hepatocellular carcinoma and hepatic hemangioma

Objective: To evaluate the diagnosis of spiral CT in small hepatocellular carcinoma and hepatic hemangioma. Methods: Summarized the experience of CT features in small hepatocellular carcinoma and hepatic hemangioma and analyzed the CT features of each. Results: Small liver lesions found in 31, 27/34 for low-density, 4/34 for high-density; hepatic hemangioma scan found lesions in 27, 24/32 for low-density, 3/32 for high density; carcinoma enhanced portal venous phase and delayed phase scanning of low-density lesion with small hepatocellular was significantly more than the arterial phase (P<0.05), and it was also more than hepatic hemangioma in portal phase and delayed phase (P<0.05). Conclusion: According to the plain and enhanced CT scans of the different characteristics of the small liver and hepatic hemangioma, it can play an effective role in the difference of the two disease, so it has some diagnostic value to be attented.
