目的 比较超声 ,CT ,PTC和ERCP对原发性胆囊癌的诊断价值。方法 74例胆囊癌病人术前分别进行了超声 ,CT ,PTC和ERCP检查 ,对这些影像学检查进行回顾性研究分析。结果 超声 ,CT和ERCP对胆囊癌的正确诊断率分别为 80 .3 % ,88.5 5和 2 5 % .7例直径 >3cm的胆囊癌中有 6例CDFI阳性。 4例伴有黄疸的病人行PTC检查的目的主要是为了PTBD减黄。结论 超声是诊断胆囊癌首选的影像学检查方法 ,CDFI在确定胆囊恶性肿瘤时很有帮助。疑似胆囊癌或有转移和进行临床分期时 ,CT较超声更有用。胆囊癌伴有黄疸的病人 ,PTC和ERCP主要以治疗为目的
Objective To compare the diagnostic value of ultrasound, CT, PTC and ERCP in primary gallbladder cancer. Methods 74 cases of gallbladder cancer were examined by ultrasound, CT, PTC and ERCP before operation. Retrospective analysis of these imaging examinations was performed. Results The correct diagnosis rate of ultrasound, CT and ERCP for gallbladder cancer was 80. 3 %, 88.5 5 and 25 %. Of the 7 gallbladder carcinomas with diameter >3 cm, 6 were CDFI positive. The purpose of PTC examination in 4 patients with jaundice was to reduce PTBD. Conclusion Ultrasound is the preferred imaging method for diagnosing gallbladder cancer. CDFI is helpful in determining gallbladder malignancy. CT may be more useful than ultrasound in cases of suspected gallbladder cancer or metastases and clinical staging. Patients with gallbladder cancer and jaundice, PTC and ERCP are mainly for treatment
