【摘要】 目的 :通过血管造影与 CT、超声的诊断结果对比研究 ,评价血管造影对小肾癌的诊断和鉴别诊断价值。方法 :2 6例肾脏小肿物病人进行了二维超声 ,CT平扫与增强 ,血管造影检查。其中 17例再行药物性血管造影。最后对它们的诊断结果做了统计分析与对比。结果 :三种检查方法的诊断检出率、特异性及符合率分别为 :血管造影 92 .9%、91.7%和 92 .3% ;CT85 .7%、16 .7%和5 3.8% ;超声 6 4.3%、33.3%和 5 0 .0 %。血管造影与 CT和超声的特异性之间存在显著性差异。结论 :血管造影尤其是药物血管造影对小肾癌的诊断和鉴别诊断具有重要价值。更多还原

【Abstract】 Objective:To evaluate angiography in the diagnosis of small renal carcinoma based on the comparative study of angiography with CT and sonography in 26 patients.Methods:26 patients with small renal masses(with diameter≤3 cm)underwent sonography and CT examination before renal angiography,pharmacoangiography was carried out additionally in 17 cases.Their results were statistically analyzed and compared with CT and sonography.Results:The sensitivity,Specificity and accuracy of these three modalities were:92.9%,91.7% and 92.3% on angiography,85.7%,16.7%and 53.8% on CT and 64.3%,33.3% and 50.5% on sonography respectively.The specificity revealed statistical difference between angiography and CT or sonography.Conclusion:Angiography,especially pharmacoangiography can be of great value in the diagnosis of small renal carcinoma.更多还原
