摘要
目的:探讨CT对胆囊癌肝浸润的诊断价值,并与B超对照。方法:回顾性分析25例经B超及CT检查并经临床证实为胆囊癌肝浸润的CT表现。结果:25例胆囊癌肝浸润的病例中有21例CT作出了正确的的诊断,大部分病例CT表现为胆囊癌肿与肝分界不清,邻近肝脏处出现不规则的低密度区,增强后呈不规则强化。而B超仅对其中的11例诊断准确。结论:CT对胆囊癌肝浸润的诊断有重要价值,且明显优于B超(P<0.005)。
Objective：To explore the value of CT diagnosis of hepatic invasion from gallbladder carcinoma,and compared with B mode ultrasonography. Methods：CT and ultrasonographic features of 25 cases of hepatic in vasion from gall- bladder carcinoma confirmed by surgery and pathology were retrospectively analyzed. Results： Of 25 cases with hepatic invasion from gallbladder carcinoma,CT diagnosed 21 accurately and 11 were diagnosed accurately by B mode ultrasonography. There was no clear demarcation between liver and gallbladder tumor in most of cases with hepatic invasion from gallbladder carcinoma,and there was marked low density area in liver adjacent to gallbladder tumor. Irregalar enhancement was observed after contrast medium administration. Conclasion：CT is valuable in diagnosing hepatic invasion from gallbladder carcinoma,the diagnostic accuracy of CT is significantly superior to that of B mode ultrasonography （P〈0. 005）.
