The systematical ultrasound investigation of the liver includes parallel sections series as well as vessel oriented sonography. The border between the right and left liver lobe runs through the middle liver vein, through portal and bile duct branchings respectively, and through the gallbladder in a sagittal direction. Liver ultrasound tomography allows differentiation of diseased liver from normal findings as well as subcategorizing into diffuse, focal, vascular, and biliary diseases. The sensitivity for fatty liver and cirrhosis ranges about 80%. The differential diagnosis of different liver diseases by ultrasound tomography will only allow suspected diagnosis. A certain differentiation between benign and malign alteration is only achieved by histological or cytological methods alone. In comparison to other indirect non invasive diagnostical procedures like computerized tomography, scintigraphy and nuclear spin tomography ultrasound tomography appears to be of primary importance.
肝脏的系统超声检查包括平行切面系列以及血管造影超声检查。肝左右叶之间的边界分别穿过肝中静脉、门静脉和胆管分支，并在矢状方向上穿过胆囊。肝脏超声断层扫描能够区分病变肝脏与正常肝脏，并进一步将其细分为弥漫性、局灶性、血管性和胆汁性疾病。对脂肪肝和肝硬化的敏感度约为80%。通过超声断层扫描对不同肝脏疾病进行鉴别诊断只能得出疑似诊断。良性和恶性病变之间的明确区分只能通过组织学或细胞学方法来实现。与计算机断层扫描、闪烁扫描和核磁共振断层扫描等其他间接非侵入性诊断程序相比，超声断层扫描似乎最为重要。
