CT 扫描为舌和口底提供了极其详细的结构。作者将CT 诊断与临床分期,手术发现进行比较,探讨舌癌患者的CT 诊断价值。患者和方法回顾确诊为舌癌的13例患者的CT 扫描和病历,患者平均年龄29岁～76岁,包括9例男性和4例女性。10例患者实行根治术,原发灶和颈淋巴结作病理.CT 扫描轴平面层距是4mm 或5mm,多数患者(8例)行冠状扫描,静脉注入100ml 造影剂,3分钟后轴平面扫描。CT 观察的肿瘤大小和局部浸润深度与临床估计进行比较,颈淋巴结最大轴径超过1cm定为转移淋巴结。结果原发灶大小在CT 中能准确识别。2例患者 CT scans provide extremely detailed structures for the tongue and floor. The authors compared the CT diagnosis with clinical stage and surgical findings and explored the diagnostic value of CT in tongue cancer patients. Patients and Methods CT scans and medical records of 13 patients diagnosed with tongue cancer were reviewed. The average age of patients was 29 to 76 years, including 9 men and 4 women. In 10 patients undergoing radical surgery, primary tumors and cervical lymph nodes were used for pathology. The CT scan axis plane distance was 4 mm or 5 mm. Coronal scan was performed in most patients (8 patients), 100 ml contrast agent was intravenously injected, and axial scan was performed 3 minutes later. The tumor size and local infiltration depth observed by CT were compared with the clinical estimates. The maximum axial diameter of cervical lymph nodes was more than 1cm as metastatic lymph nodes. Results The size of the primary lesion can be accurately identified in CT. 2 patients
