肝动脉造影CT和经动脉门脉造影CT在肝脏小结节病变诊断中的价值

Diagnostic valuation of CT hepatic arteriography and CT arterial portography in small liver pathogenic nodules

目的探讨螺旋CT扫描在肝动脉造影CT(CThepaticarteriography,CTHA)和经动脉门脉造影CT(CTarterialportogra-phy,CTAP)在肝脏小结节病变中的应用价值。方法对76例肝脏的10个小结节病变行CT双期扫描、CTHA/CTAP检查对比。结果CTHA/CTAP病灶检出率为90.72%,CT双期扫描的检出率为70.10%,两者具有显著性差异(P<0.01)。结论CTHA/CTAP可提高CT图像质量,对病灶检出率高于双期增强扫描,结合临床能显著提高小肝癌的检出率。

Objective To evaluate the significance of both spiral CT hepatic arteriography （CTHA） and CT arterial portography （CTAP） in diagnosis of small liver nodules. Methods The CTHA / CTAP manifestations of 108 small liver nodular lesion from 76 patients with liver cirrhosis were analyzed and compared with those in bi-phase enhanced CT. Results The detection rate for CTHA/CTAP（90.72% ） was significantly higher than the positive rate （70.10%） for the bi - phase enhanced CT（P〈0.01）.Conclusion With the use of spiral CT technique, the quality of CT images in CTHA/CTAP is significantly improved. CTHA/CTAP techniques can increase the sensitivity of diagnosis for small livers nodules which is very helpful in findings of small hepatocellular carcinoma.
