超声及超声造影与增强CT对小肾癌诊断的对照研究

Comparison of ultrasound and ultrasonic contrast versus contrast-enhanced CT in the diagnosis of small renal cell carcinoma

目的探讨超声、超声造影以及增强CT在小肾癌中的诊断价值,提高小肾癌的诊断水平。方法回顾性分析55例直径小于4cm肾占位患者的B超、CT检查结果 ,并结合临床病理资料对其中20例小肾癌患者的超声造影检查结果和增强CT结果作对比研究。结果各种影像学检查手段诊断小肾癌的准确率分别是:B超78.18%、CT92.73%、超声造影90.00%。超声造影与螺旋CT对于小肾癌的诊断差异无统计学意义。结论 B超是筛选小肾癌的首选方法 ,螺旋增强CT为小肾癌定性、定位诊断提供重要参考,超声造影对小肾癌的诊断具有较高的价值。

Objective To evaluate the value of ultrasound,ultrasonic contrast,and contrast-enhanced CT scan for diagnosing the small renal cell carcinoma,and to improve its diagnostic level. Methods The imaging characteristics of ultrasound and CT in 55 patients with small renal cell carcinoma were retrospectively analyzed.The diagnosis consequences of ultrasonic contrast and CT were compared in 20 of 55 patients. Results In all cases the diagnostic accuracy for small renal cell carcinoma was 78.18% for ultrasound,92.73% for contrast-enhanced CT,and 90.00% for ultrasonic contrast.There was no significant difference in diagnosis accuracy between ultrasonic contrast and CT. Conclusion Ultrasound is the first selection for screening small renal cell carcinoma,while multislice spiral CT offers an important reference value for the qualitative and level diagnosis.
