目的：了解影像学方法在鉴别诊断婴儿阻塞性黄疸方面的作用。方法：对９４例年龄８～１２０天阻塞性黄疸患儿进行Ｂ超、肝胆核素动态和ＣＴ检查。结果：肝胆核素动态检查５８例，符合４１例；Ｂ超检查７０例，符合５１例，其中１５例加做肝门纤维块观察；１１例胆道闭锁，１０例可见肝门纤维块；４例婴儿肝炎未见肝门纤维块。ＣＴ检查１２例，无法提出可靠的正确诊断依据。结论：６０天以内阻塞性黄疸鉴别诊断困难。年龄越小，诊断越困难。肝胆核素检查诊断胆道闭锁准确，但常把婴儿肝炎误为胆道闭锁。Ｂ超观察肝外胆道闭锁误诊率高，观察进食前后胆囊变化，可提高诊断率，而观察肝门部纤维块则更准确。ＣＴ检查作用有限
Objective: To understand the role of imaging in the differential diagnosis of obstructive jaundice in infants. Methods: 94 children aged 8 to 120 days with obstructive jaundice in children with B ultrasound, hepatobiliary radionuclide dynamic and CT examination. Results: The dynamic examination of liver and gallbladder radionuclides in 58 cases, consistent with 41 cases; B ultrasound examination of 70 cases, consistent with 51 cases, of which 15 cases of hepatic fibrosis were observed; 11 cases of biliary atresia, 10 cases of hepatic fibrosis can be seen; 4 cases Hepatitis no liver fibrosis block. CT examination in 12 cases, unable to provide a reliable basis for the correct diagnosis. Conclusion: The diagnosis of obstructive jaundice within 60 days is difficult. The younger, the more difficult the diagnosis. Hepatobiliary diagnosis of biliary atresia accurate, but often mistaken for infant biliary atresia. B ultrasound observation of extrahepatic biliary atresia misdiagnosis rate, observation of gallbladder before and after eating changes, can improve the diagnostic rate, while the observation of the hilar fiber block is more accurate. CT examination is limited
