CT动态增强对原发性胆囊癌的诊断价值

Value of Dynamic Enhanced CT in the Diagnosis of Primary Gallbladder

目的探讨CT动态增强对原发性胆囊癌的诊断价值。方法回顾性分析广州医科大学附属肿瘤医院术后病理确诊为胆囊癌(60例)、确诊为胆囊良性肿瘤(40例),正常受检者(40例)的上腹部CT动态增强扫描资料。分别测量各组胆囊内胆汁的CT值,以及胆囊癌和良性肿瘤组病灶的平扫、动脉期、门脉期CT值,进行统计学分析,每个测量值均取三次测量的平均值。结果胆囊癌组胆汁CT值(15.86±1.78HU)高于良性统计学分析肿瘤组(10.50±0.94 HU)和正常对照组(7.75±1.41HU),差异有统计学意义(P<0.05)。胆囊癌组病灶平扫(36.13±1.52)、动脉期(52.38±3.01)、门脉期CT值(71.38±5.06)均高于胆囊良性肿瘤组(29.75±1.92、43.63±1.81、5 6.6 3±3.2 6),差异有统计学意义(P<0.0 5)。胆囊癌组中男女比例为1:2.2,良性肿瘤组中男女比例为1.4:1。结论胆囊内胆汁的CT值与肿瘤平扫、动脉期及门脉期CT值对原发性胆囊癌具有一定的辅助诊断价值。

Objective Explore the value of dynamic contrast-enhanced CT in the diagnosis of primary carcinoma of gallbladder. Methods The upper abdomen CT datas of 60 cases primary carcinoma of gallbladder, 40 cases of gallbladder benign tumor which proved by pathology and 40 cases of normal people were retrospective analyzed. All of the cases came from Guangzhou Medical University Cancer Hospita. The CT values of the bile and lesions in the gallbladder were measured at plain scan, arterial phase, portal venous phase. The averaged of every 3 measure value were recorded, and statistical analysis were made. Results Gallbladder bile CT group is higher than the other groups, and the comparison was statistically significant（P〈0.05）. Gallbladder lesions group unenhanced, arterial, portal venous phase CT valuesare higher than the gallbladder benign group, comparing it with statistical significance（P〈0.05）. Conclusions The CT valuesof the gallbladder bile and tumor has certain diagnostic value of primary carcinoma of gallbladder.
