摘要
目的探讨肝硬化再生结节的CT诊断及鉴别,提高肝内结节的诊断水平。方法对25例肝硬化再生结节的CT平扫及增强图象回顾性分析。结果25例肝硬化再生结节,直径大于3cm的结节为大结节型6例,直径位于10～30mm的为小结节型8例,,两种并存的为混合型11例。平扫低密度1例,等密度3例,高密度21例。增强扫描动脉期结节强化8例,门脉期强化且与肝脏密度相等15例,延迟期为高密度1例,低密度1例。结论螺旋CT双期扫描一般能明确肝硬化再生结节的诊断,也利于与肝癌、肝血管瘤的鉴别。
To evaluate the diagnosis and differentiation of CT for hepatocirrhotic nodules, to improve the level of liver nodules. Methods Analyze CT plain scanning and contrast enhancement images about the 25 cases hepatocirrhotic nodules. Resuits Of the 25 cases, there are six cases with big nodules, more than 30 mm in diameter, 8 cases with small nodules between 10 mm to 30 mm, ll cases with mixed type in which there are both big and small nodules. On plain scans, one case appeared hyodense, 3 cases appeared isodense, and 21 cases appeared hyperdense, and On the arterial phase images, 8 cases showed enhanced, and 15 cases enhanced on portal vein phase images. On the delaying phase images one case showed hyodense and another case showed hyperdense Conclusion Spiral CT scans can make a definite diagnosis of hepatocirrhotic nodules, which helps to differentiate between liver caner and liver hemangioma.
