On computed tomographic scans of the upper abdomen the interface sign can help distinguish pleural and intra-abdominal fluid readily and accurately. A hazy interface between the fluid and liver or spleen is characteristic of pleural fluid. A sharp interface is characteristic of ascites. The interface sign has proved to be accurate in 30 consecutive cases.
在上腹部计算机断层扫描中，界面征有助于快速、准确地区分胸腔积液和腹腔积液。液体与肝脏或脾脏之间模糊的界面是胸腔积液的特征。清晰的界面是腹水的特征。界面征在连续30例病例中已被证明是准确的。
