目的探讨3种常用影像学方法(B超、多层螺旋CT、MRI)在小肾癌临床中的应用并比较其价值。方法回顾性分析68例病理学证实小肾癌患者的B超、螺旋CT、MRI检查结果,进一步结合临床及病理资料对3种检查结果作对比研究。结果 3种影像学检查在小肾癌的诊断中准确率分别为:B超82.35%(56/68)、MRl 82.05%(32/39)、螺旋CT 93.85%(61/65),B超及MRI对于小肾癌的诊断差异无显著性(P>0.05),多层螺旋CT具有显著优越性,准确率显著高于前两者(P<0.05)。结论临床中可综合应用3种影像学检查方法,B超可用于小肾癌的筛查,MRI对小肾癌集合系统判断及与肾盂癌鉴别诊断具有较高的价值,增强CT可作为小肾癌定性、定位诊断最重要的方法。
Objective To investigate the clinical application of three common imaging methods (B-mode, multi-slice spiral CT and MRI) in the diagnosis of small renal cell carcinoma and to compare their value. Methods A retrospective analysis of 68 cases of pathologically confirmed renal cell carcinoma in patients with B ultrasound, spiral CT, MRI examination results, and further combined with clinical and pathological data on the three kinds of test results for comparative study. Results The accuracy rates of three kinds of imaging examination in small renal cell carcinoma were 82.35% (56/68) in B ultrasound, 82.05% (32/39) in MR, 93.85% (61/65) in spiral CT, There was no significant difference between the two groups in the diagnosis of small renal cell carcinoma (P> 0.05). The multi-slice spiral CT has the remarkable superiority, the accuracy is significantly higher than the former two (P <0.05). Conclusions Three kinds of imaging examination methods can be comprehensively applied in clinic. B ultrasound can be used for small renal cell carcinoma screening. MRI is of great value in judging the small renal cell carcinoma aggregation system and differential diagnosis of renal pelvic cancer. Enhanced CT can be used as small kidney Cancer qualitative, the most important method of localization diagnosis.
