Ultrasonography, as screening method of choice, answers questions as to the size of the liver, the structure of the parenchyma, focal lesions and the dilatation of the biliary system. To characterize focal lesions, to stage tumors and for a better topographic localization, computed tomography or magnetic resonance imaging is useful. The differential diagnosis of focal lesions, such as cysts, hemangioma or focal nodular hyperplasia is achieved by the combination of laboratory, imaging and nuclear medicine methods. In other cases, needle-biopsy under sonographic or CT guidance is decisive.
超声检查作为首选的筛查方法，可回答有关肝脏大小、实质结构、局灶性病变及胆道系统扩张的问题。为了对局灶性病变进行特征描述、对肿瘤进行分期以及更好地进行定位，计算机断层扫描或磁共振成像很有用。通过实验室、影像学和核医学方法的联合可实现对局灶性病变（如囊肿、血管瘤或局灶性结节性增生）的鉴别诊断。在其他情况下，超声或CT引导下的针吸活检具有决定性意义。
