摘　　要：目的比较多层螺旋CT(MSCT)与多普勒超声对膀胱不同部位肿瘤的诊断价值。方法以我院2013年2月-2015年10月经手术病理证实的50例膀胱肿瘤患者为研究对象,术前均行MSCT平扫、增强扫描及多普勒超声检查,以手术病理结果为对照,比较不同检查方法对膀胱肿瘤良恶性、不同部位肿瘤检出情况。结果MSCT诊断膀胱癌敏感度、特异度、准确度分别为93.5%、75.0%、92.0%。较多普勒超声诊断的82.6%、75.0%、82.0%差异无统计学意义(P>0.05)。MSCT延迟期对膀胱颈部、三角区肿瘤检出率、任何部位肿瘤检出率分别为75.0%、76.9%,显著高于多普勒超声检查的47.1%、56.5%及MSCT平扫的44.1%、52.8%,差异有统计学意义(P<0.05);不同检查方法对膀胱颈部、三角区以外其他部位肿瘤检出率比较差异无统计学意义(P>0.05)。结论多普勒超声、MSCT对膀胱癌诊断准确率均较高,MSCT在膀胱颈部及三角区肿瘤检出方面优于多普勒超声,临床灵活运用MSCT后处理技术以提高肿瘤病灶检出率。[Objective To compare the diagnostic value of Doppler ultrasonography and multi-slice spiral CT （MSCT） in neoplasms in different sites of bladder. Methods 50 cases of patients with bladder neoplasms confirmed by surgery and pathology who were admitted in our hospital between February 2013 and October 2015 were selected as the study objects. Before surgery, all of them underwent MSCT plain scan, enhanced scan and Doppler ultrasonography. The results of surgery and pathology were taken as control to compare the detection rates of different methods in benign and malignant bladder neoplasms and neoplasms in different sites. Results The sensitivity, specificity and accuracy of MSCT in the diagnosis of bladder neoplasms were 93.5%, 75.0% and 92.0%, respectively while those of Doppler ultrasonography were 82.6%, 75.0% and 82.0%, respectively （P〉0.05）. The detection rates of MSCT delayed phase in neoplasms in bladder neck and trigonum and neoplasms in any site （75.1）%,, 76.9%） were significantly higher than those of Doppler ultrasonography （47.1%, 56.5%） and MSCT （44.1%, 52.8%） （P〈0.05）. There was no significant difference in the detection rate of neoplasms in bladder neck, trigonum and other sites between different examination methods（P〉0.05）.Conclusion The accuracy rates of Doppler ultrasonography and MSCT in the diagnosis of bladder cancer are high. MSCT in detection of neoplasms in bladder neck andtrigonum is superior to Doppler ultrasonography. In clinic, flexible application of MSCT post- processing technique can improve the detection rate of tumor lesions.
