【摘要】 目的探讨多层螺旋CT对泌尿系梗阻疾病的诊断价值,了解非增强CT、增强CT在临床诊断中的优势及后处理技术特点。方法收集经手术及临床证实且术前有完整的多层螺旋CT及B超、静脉肾盂造影(IVP)检查的,临床怀疑有泌尿系统梗阻性疾病的病例72例。结果 CT的诊断效果最好,其诊断符合率明显高于B超及IVP检查(P<0.05);非增强CT的定性诊断、定位诊断复合率均明显高于B超、IVP(P<0.05);曲面重建和多平面重建准确率均为80.5%,高于容积重建(61.1%)和最大密度投影(55.6%)(P<0.05)。结论多层螺旋CT比以往传统的影像学检查方法的诊断更符合手术的结果 ,说明多层螺旋CT在诊断泌尿系梗阻性疾病存在优势。更多还原

【Abstract】 Objective To explore the diagnostic value of multi-slice spiral CT in urinary tract obstruction diseases,and learn the superiority and after-finishing technical characteristics of non-enhanced CT and CTU.Methods Collected 72 cases of urinary tract obstruction diseases through multi-slice spiral CT and Ultrasound,Intravenous pyelography.Results CT had the best diagnostic effect,as its’ diagnose accordance rate was much higher than ultrasound and intravenous pyel ography (P < 0.05).The diagnose accordance rate in qualitation and naiveau diagnosis of non-enhanced CT were much higher than ultrasound and intravenous pyelography (P < 0.05).The accurate rate in toroidal and multiplanar reconstruction were both 80.5%,higher than in volume reconstruction (61.1%) and maximum intensity projection (55.6%) (P < 0.05).Conclusion Multi-slice spiral CT has a better diagnostic effect than traditional imageology inspection which indicates that multi-slice spiral CT exists superiority of diagnosing urinary tract obstruction diseases.更多还原
