Ultrasound examination with a two-dimensional recording technique has proved increasingly useful in obstructive biliary disease and in abnormalities of the liver parenchyma causing a reduction in biliary contrast excretion. In particular, hydrops of the gall bladder, cholelithiasis and choledocholithiasis and choledocholithiasis can be demonstrated where there is biliary obstruction. Analysis of various planes of section is particularly useful in showing obstruction due to the head of the pancreas. The introduction of grey scale techniques and focussed transducers of various frequencies and sizes, suggests that there will be further improvements in the sonographic diagnosis of the hilum of the liver and of the intrahepatic biliary passages.
二维记录技术的超声检查在梗阻性胆道疾病以及导致胆汁造影剂排泄减少的肝实质异常中已证明越来越有用。特别是，在存在胆道梗阻的情况下，可以显示胆囊积水、胆结石、胆总管结石和肝外胆管结石。分析不同的切面对于显示胰腺头部引起的梗阻特别有用。灰阶技术以及各种频率和尺寸的聚焦换能器的引入，表明肝脏门部和肝内胆管的超声诊断将有进一步的改进。
