CT与B超对胰头癌诊断的对比分析

目的 探讨胰头癌的超声学特点和B超在胰头癌诊断中的价值.方法 对38例疑为胰腺癌患者进行胰腺B超检查及CT检查,并与病理结果对照.同时对比观察B超和CT在胰头癌诊断中的异同.结果 38例疑为胰腺癌的患病者最终有28例证实为胰头癌患者,B超检查检出21例,诊断符合率为75.0%,CT检出24例,诊断符合率为85.7%.B超与CT比较,各项观察指标均无统计学差异（P均＆gt;0.05）.结论 B超和CT对胰头癌检查诊断符合率基本一致.

The study of comparison between ultrasound B and CT in diagnosing carcinoma of head of pancreas

Objective To discuss the ultrasonic feature of the carcinoma of head of pancreas and the value of ultrasound B in diagonosing carcinoma of head of pancreas. Methods Thirty-eight cases suspected to have the carci- noma of head of the pancreas were given ultrasound B and CT scan respectively,the results were judged by pathology. In addition,compared to CT,the value of ultrasound B in diagnosing carcinoma of head of pancreas was analyzed. Resuits Twenty-eight of 38 cases suspected to have carcinoma of head of the pancreas were verified by pathology, ul- trasound B found 21 cases with the diagnostic rate of 75. 0%. CT uncovered 24 cases with the diagnostic rate of 85.7%. Compared with CT, ultrasound B had no significant difference statistically in exposing liver metastasis, the infiltration in retroperitoneal lymphadenectasis,dilated choledoch and hepaticopancreatic duct, et al. Conclusion Ultrasound B and CT were paralleled in diagnosis of carcinoma of head of pancreas.
