摘要
评价ＣＴ在梗阻性黄疸检查中定位和定性诊断的准确性。回顾性分析经手术、病理和ＣＴ追踪确诊的、术前均行ＣＴ检查的梗阻性黄疸病变５４例，良性２１例，恶性３３例。本组资料均显示梗阻性黄疸病变中有不同程度的肝内或／和肝外胆管扩张，部分合并胆囊扩大。其ＣＴ表现均显示为低密度环状或条状影，胆囊直径增大。ＣＴ诊断梗阻平面的准确性为１００％，对梗阻性黄疸定性诊断的准确性为８５２％。肝胆管扩张的程度和梗阻平面的形态学表现对定性诊断具有重要价值。ＣＴ对梗阻性黄疸的定位诊断具有高度的准确性，ＣＴ结合其它影像学检查方法和临床资料综合分析，可提高定性诊断梗阻性黄疸的准确性。
To evaluate the accuracy of CT in determing the level of obstruction and the cause of jaundice.Materials and Methods:preoperative CT images 54 consecutive cases of obstructive jaundice(21 benign and 33 malignant)by surgery,physiology and follow-up CT proved were analyzed retrospectively.Results:Dilatation of intrahepatic and/or extrahepatic bile duct was shown in each case in its degree,while conbination with enlargement of gallbladder in some caseshypodensity circles,stripes and enlargement of gallbladder were seen in CT images.The accuracy in determing the level of obstruction and the causes of jaundice with CT were 100%and 85.2%,reospectively.It is highly important for diagnosing the causes of jaundice to show dilatation of intrahepatic and extrahepatic bile duct and morphology of the level of obstruction.Conclusion:It is very accurate in detemming the level of obstruction with CT study in combination with some other modalities and the clinical materials would improve the accuracy in diagnosing the causes of jaundice.
