摘要
目的 :探讨等密度肝癌的检查及价值。材料与方法 :对CT平扫检查无明显 ,再行CT增强扫描的 13例等密度肝癌病例进行分析。结果 :CT平扫为等密度 ,2例引起肝局部轮廓改变 ,2例可见晕环 ;增强扫描有其特征表现 ,9例为低密度 ,2例为略低密度 ,延迟扫描仍为低密度 ;直径小于 2cm的 9例 ,2cm～ 4cm的 4例。结论 :①小肝癌在CT平扫上呈等密度居多。②等密度肝癌的检查应先B超后CT平扫和增强 ,从而避免漏诊。
Purpose:To discussion the check method and value of the same density hepatolarcinoma with liver.Materials and Methods:Analysis the 13 cases same density hepatolarcinoma with liver,we found no abnormality by CT plain scan,and found the ddensity of hepatolarcinoma being equal with liuer by stcontrast enhancement.Results:All the 13 cases are the same density hepatolarcinoma with liver by CT plain scan,2 cases being founded local contour altered,and 2 cases found a ring with its milieu.We found 9 cases in low density,2 cases is equal density by CT ctcontrast enhancement,but all are low density by delay scan.In 13 cases,we found 9 cases diameler were no more than 2cm and 4 cases were between 2cm and 4cm.Conclusion:First:most of small hepatolarcinoma are the same density with liver;second:in order to obtuse marginal artery missed diagnosis,we must check first B-us,then CT piain scan and ctcontrast enhancement.
