超声波(US)、CT 能无损伤地观察胆汁郁滞的胆道系统,有助于鉴别梗阻和非梗阻性原因。US、CT、MRI 对肝脏具有高分辨能力,可发现肝内占位性病变,某些情况下甚至可判断病变的性质。ERCP 和PTC 不仅在判断病灶的存在和胆道梗阻原因方面优于无损伤性影像检查,而且操作者能够进行活检,兼治梗阻病因。由于这些设备(除MRI 外)都普遍应用而其功能不少重复,因而给合理使用带来困难。本文旨在根据所得资料和作者目前使用肝脏影像检查的情况提出一些看法。肝脏影像检查的费用问题无损伤检查结合更为正确,但属侵入性的 Ultrasound (US), CT can be nondestructive observation of cholestatic biliary system, help identify obstruction and non-obstructive causes. US, CT, MRI High resolution of the liver can be found intrahepatic space-occupying lesions, and in some cases can even determine the nature of the lesion. ERCP and PTC are superior to noninvasive imaging in determining the presence of lesions and the cause of biliary obstruction, and the operator is able to perform biopsy and manage the cause of obstruction. Because these devices (except MRI) are widely used and their functions are repeated, which brings difficulties to rational use. The purpose of this article is to make some observations based on the information available and the author’s current use of liver imaging. The cost of liver imaging examinations without damage more accurate, but invasive
