影像学检查在小肾癌诊断中的临床应用及比较

Clinical application and comparison of imaging examinations in the diagnosis of small renal cell carcinoma

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 study the clinical application and to compare the significance of B-ultrasonography,multiple spiral CT （MSCT） and MRI in the diagnosis of small renal cell carcinoma. Methods B-ultrasonography,MSCT and MRI data of 68 cases of small renal cell carcinoma confirmed by pathological examination were retrospective analyzed and compared. Results The diagnosis accuracy rates of B-ultrasonography, MSCT and MRI were 82.35% （56/68）, 93.85% （61/65） and 82.05% （32/39）. There was no significant difference between the accuracy rate of B-ultrasonography and MRI （P〉0. 05） ,but the accuracy rate of MSCT was significantly higher than that of the others （P〈0. 05）. Conclusions The 3 imaging methods can be used comprehensively in the diagnosis of small renal carcinoma,B-ultrasound for screening,MRI for differential diagno- sis with renal pelvis carcinoma,and MSCT for qualitative diagnosis and positioning.
