摘要
目的:对比分析超声与MRI在喉癌诊断及术前T分期中的临床应用价值。方法:36例喉癌患者术前分别行超声及MRI检查,并与手术所见和病理结果进行对照分析。结果:36例喉癌,超声检出34例,MRI检出32例。在T分期中,超声对T1、T2、T3、T4期喉癌分期的准确度分别为90.9%、60.0%、87.5%、85.7%,MRI分别为63.6%、70.0%、75.0%、100%,两者准确度差异无统计学意义(χ2值分别为2.329、0.220、0.410、1.077,P值均>0.10)。超声和MRI对肿瘤T分期总体符合率分别为80.6%和75.0%,两者结果比较差异无统计学意义(χ2=0.321,P=0.778)。结论:超声能对喉癌的位置、大小及肿瘤浸润范围提供较为全面的信息,可作为纤维喉镜和CT、MRI等检查的有效补充。
Objective： To compare the value of ultrasonography and MR imaging in diagnosing and T-staging of laryngeal carcinoma.Methods： Ultrasonography and MRI were performed in thirty-six patients with laryngocarcinoma.Histopathologic and surgery findings were performed to validate imaging findings.Results： In 36 patients with laryngeal carcinoma,34 cases were found by ultrasonography,32 cases were detected on MRI.The accuracy of ultrasonography and MRI in the diagnosis of T1,T2,T3,T4 staging laryngocarcinoma were 90.9%,60.0%,87.5%,85.7% and 63.6%,70.0%,75.0%,100%,respectively.There were no statistical differences observed in accuracy rating between ultrasonography and MRI（χ2 were 2.329,0.220,0.410,1.077,respectively,all P0.10）.The overall accuracy rating in T-staging was 80.6% for ultrasonography,and was 75.0% for MRI.There was no significant difference between the two methods in overall T-staging accuracy rating（χ2=0.321,P=0.778）.Conclusions： Ultrasonography can provide adequate information with the location,size and infiltration of laryngeal carcinoma,it is a complementary method for laryngoscopy,CT and MR imaging assessment of laryngeal carcinoma.
