摘要
目的 探讨磁共振-弥散加权成像(MR-DWI)对喉癌T分期的诊断价值及预后的预测价值.方法 158例喉癌手术患者均于术前、放疗后6个月接受MRI检查.以病理检查结果为金标准,比较常规MRI和MR-DWI检查对喉癌的检出情况及其诊断喉癌T分期的结果与病理检查结果的一致性,以及不同预后喉癌患者MR-DWI检查的表现弥散系数(ADC)值.结果 MR-DWI检查对喉癌的检出率明显高于常规MRI检查,差异有统计学意义(P﹤0.01).MR-DWI检查诊断喉癌T分期的结果与病理检查结果的一致性Kappa值为0.869,高于常规MRI检查的0.703.放疗后6个月,未复发患者的ADC值明显高于复发患者,差异有统计学意义(P﹤0.01).结论 MR-DWI检查对喉癌的检出率较高,其诊断喉癌术前T分期的结果与病理检查结果的一致性也较高,并且能预测喉癌患者的预后.
Abstract
Objective To investigate the diagnostic value of magnetic resonance-diffusion weighted imaging(MR-DWI)for T-staging of laryngeal cancer and its prognostic predictive value.Method A total of 158 patients with larynge-al cancer underwent MRI examination before surgery and 6 months after radiotherapy.Pathological examination results were used as the gold standard,the detection of laryngeal cancer by conventional MRI and MR-DWI examination,the consistency between the results of T-stage diagnosis of laryngeal cancer by conventional MRI and MR-DWI examination and the results of pathological examination,and the apparent diffusion coefficient(ADC)values of MR-DWI examina-tion in patients with different prognosis of laryngeal cancer were compared.Result The detection rate of laryngeal can-cer by MR-DWI examination was significantly higher than that by conventional MRI examination,and the difference was statistically significant(P<0.01).The Kappa value for consistency between the results of MR-DWI examination and and the results of pathological examination in the diagnosis of T stage of laryngeal cancer was 0.869,which was higher than 0.703 of conventional MRI examination.At 6 months after radiotherapy,ADC value of patients with no recurrence was significantly higher than that of patients with recurrence,and the difference was statistically significant(P<0.01).Conclu-sion The detection rate of laryngeal cancer by MR-DWI examination is high.The consistency between the results of MR-DWI examination and and the results of pathological examination in the diagnosis of T stage of laryngeal cancer is al-so high,which can predict the prognosis of laryngeal cancer patients.
