摘　　要：目的:探讨多层螺旋CT增强扫描及多平面重组技术在喉癌患者术前分型、分期中的诊断价值,并分析影响CT诊断的因素。方法:对41例电子喉镜检查并经术后病理证实为喉癌的患者,行术前CT扫描及多平面重组,根据图像资料进行临床分型、分期,并与术中所见及术后病理结果对照比较。结果:CT诊断肿瘤侵犯范围总的符合率为81.9%,假阴性率为9.3%,敏感性为90.7%。术前T分期的符合率分别为T1期80.0%、T2期66.7%、T3期52.6%、T4期72.7%;术前N分期的符合率分别为N1期58.3%、N2期100%。结论:螺旋CT平扫、增强扫描及多平面重组图像能够很好地显示喉癌的形态、大小、侵犯范围及淋巴结转移等,对肿瘤术前分型、分期及制定合理的治疗方案具有指导意义。Objective： To evaluate the significance of multi-slice CT with multiplanar reconstruction（MPR） and enhanced scanning in preoperative classification,staging of laryngeal carcinoma,and to analyze the factors of influence.Methods： Forty-one patients with laryngeal carcinoma diagnosed by electrical laryngoscope were studied by preoperative CT examination and MPR.Its images were used to investigate the classification and staging of tumor,the findings were compared with pathological results.Results： The overall positive predictive value of CT in assessing tumor invasion was 81.9%,false negative rate was 9.3%,the sensitivity was 90.7%.In preoperative T staging,T1,T2,T3 and T4 were 80%,66.7%,52.6%,72.7% respectively.In preoperative N staging,N1 was 58.3%,N2 was 100%.Conclusion： The CT images with MPR and enhanced scan can display shape,size,invasion and lymph node metastasis,and it is of essential value in typing,staging and establishment of reasonable treatment.
