螺旋CT多期增强在胆囊癌诊断中的价值

目的探讨螺旋CT多期增强扫描在胆囊癌诊断中的价值.方法回顾分析经手术病理证实的42例胆囊癌的多期增强的螺旋CT表现.结果胆囊癌具有一定的强化特点,表现为动脉期明显高密度,门脉期呈等密度或高密度,延迟期消退不明显,即胆囊癌的3期增强强化程度高于正常胆囊壁和肝脏,且强化时值明显延长.结论胆囊癌的SCT多期强化特征对胆囊癌的诊断与鉴别诊断有重要价值.

Application of multi-phasic spiral CT scan to gallbladder carcinoma diagnosis

Objective To explore the value of the multi-phasic spiral CT scan in the diagnosis of gallbladder carcinoma.Methods The characteristic CT findings were reviewed in 42 cases with gallbladder carcinoma proven pathologically.Results The gall bladder carcinoma had certain enhancing characteristics: high density in hepatic artery period,same or high density in porch vein period,and no clear fadeaway in delaying period.In other words,the gall bladder carcinoma was higher enhancement than normal gallbladder wall and liver,and had long-term enhancement.Conclusion The multi-phasic spiral CT scan plays an important role in diagnosis and differential diagnosis of gallbladder carcinoma.
