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。
OBJECTIVE: To compare the diagnostic results of angiography with CT and ultrasonography and evaluate the value of angiography in the diagnosis and differential diagnosis of small renal cell carcinoma. Methods: Twenty-six patients with small renal masses underwent two-dimensional ultrasonography, CT scan and contrast enhancement and angiography. Among them, 17 cases were reexamined with drug-induced angiography. Finally, the results of their diagnosis made a statistical analysis and comparison. Results: The diagnostic accuracy, specificity and coincidence rates of the three methods were as follows: angiography 92.9%, 91.7% and 92.3%; CT85.7%, 16.7% and 53.8% 6 4.3%, 33.3% and 50.0%. There was a significant difference between the specificity of angiography and CT and ultrasound. Conclusion: Angiography, especially drug angiography, is of great value in the diagnosis and differential diagnosis of small renal cell carcinoma.
