【摘要】 目的探讨多层螺旋CT多期扫描对早期肾盂癌的诊断价值。方法回顾性分析58例肾盂癌的CT表现并进行CT分期,与组织病理学结果对照。结果 CT图像分期A期(早期)18例、B期32例、C期8例;病理分期早期(A期)24例、B期26例、C期8例。24例A期肾盂癌中,CT分期正确的17例,7例A期误判为B期,1例B期误判为A期。CT评判早期肾盂癌的敏感性70.8%(17/24),特异性97%(32/33),阳性预测值94.4%(17/18)%。结论多层螺旋CT多期扫描对早期肾盂癌的判断有很高的特异性,对临床手术方案的选择起到很好的指导作用。更多还原

【Abstract】 Objective To investigate the diagnostic value of enhanced multi-phase spiral CT in the early renal pelvis cancer.Methods CT manifestations of 58 cases with renal pelvis cancer were retrospectively analyzed and CT staged,and compared to its pathological results.Results CT image stage showed A stage (early stage) in 18 cases,B stage in 32 cases,C stage in 8 cases;pathological stage showed A stage (early stage) in 24 cases,B stage in 26 cases,C stage in 8 cases.Of all 24 cases with A stage renal pelvis cancer,17 cases were diagnosed correctly,and 7 cases with A stage cancer were misdiagnosed as B stage,and 1 case with B stage cancer misdiagnosed as A stage.The sensitivity,specificity,positive predictive value of CT stage in evaluation of early renal pelvis cancer were 70.8% (17/24),97% (32 /33),and 94.4% (17 /18) %.Conclusion Enhanced multi-phase spiral CT has high specificity in diagnosis of early stage renal pelvis cancer.It plays an important role in clinical operation scheme selection.更多还原
