目的探讨CT、MRI对喉癌侵及范围及治疗方案选择的价值。方法分析35例喉癌患者平扫及强化CT、M RI显示声门上区、声门下区、声带、前联合、甲状软骨、声门旁间隙、杓状软骨肿瘤原发或侵及部位及颈部淋巴结转移情况,并与喉镜及手术病理结果对照。结果 MRI平扫及强化显示声门上区、声门下区、声带、前联合、甲状软骨、声门旁间隙、杓状软骨病变及颈部淋巴结转移数多于CT,但无统计学差异,MRI平扫及强化敏感性一致,均高于CT平扫及强化,CT强化敏感性高于CT平扫;平扫及强化MRI、CT特异性、阳性预测值基本一致;MRI平扫、强化及CT强化Kappa值基本一致,均高于CT平扫;MRI平扫及强化阴性预测值一致,均高于CT平扫及强化,CT平扫及强化阴性预测值基本一致。结论 MRI对喉癌侵及范围及治疗方案选择较CT能够提供更多信息。
Objective To investigate the value of CT and MRI in evaluating the extent of laryngeal cancer invasion and treatment options. Methods Thirty-five cases of laryngeal cancer were analyzed by plain scan and enhanced CT. M RI showed the location of supraglottic area, subglottic area, vocal cord, anterior commissure, thyroid cartilage, paraglottic space and the primary site or neck of arytenoid cartilage Department of lymph node metastasis, and with laryngoscope and surgical pathology results. Results MRI scan and enhancement showed that the supraglottic area, subglottic area, vocal cord, anterior commissure, thyroid cartilage, paratubal glotticus, arytenoid cartilage lesions and cervical lymph node metastases were more than CT, but no statistical difference was found The sensitivities of plain scanning and enhanced scanning were the same as those of CT scan and CT scan, and the sensitivity of CT scan was higher than that of CT scan. The specificity of CT scan and enhanced CT scan were the same as those of CT scan. The Kappa values were basically the same, all higher than those of CT scan. The MRI plain scan and the enhanced negative predictive value were the same, which were all higher than those of CT scan and enhanced scan. The CT scan and the enhanced negative predictive value were basically the same. Conclusion MRI can provide more information on the extent of laryngeal cancer invasion and treatment options than CT.
