为比较CT和MR在鼻咽癌(NPC)分期及放疗后随访的价值,作者分析了1985年～1993年间意大利Florence大学放疗科收治的53例NPC,均为有病理诊断的上皮源性癌。用第三代CT作平扫和增强扫描,用0.5和1.5TMR机作矢状面、冠状面和横断面扫描。53例均行根治性放疗。一般在放疗后至少2个月作基线扫描。随访病例中37例为此期间放疗者,16例为1985年即已开始随访。结果见到,在14例CT示口咽受侵犯者中MR发现6例有咽后淋巴结肿大,而CT和MR均示这14例有咽旁间隙受累。此外,MR发现14例有颈前肌受累。在显示骨受累方面,
To compare the value of CT and MR in the follow-up of nasopharyngeal carcinoma (NPC) stage and post-radiotherapy, the authors analyzed 53 NPC patients admitted to the Department of Radiation Oncology, University of Florence, Italy from 1985 to 1993, all of which were pathologically diagnosed epitheliogenic carcinomas. With third-generation CT scan and enhanced scan, with 0.5 and 1.5TMR for sagittal plane, coronal plane and cross-sectional scan. 53 patients underwent radical radiotherapy. Baseline scans are generally performed at least 2 months after radiotherapy. Follow-up cases in 37 cases of radiotherapy during this period, 16 cases were started in 1985 that follow-up. The results showed that in 14 cases of CT showed oropharyngeal involvement of the MR were found in 6 cases of retropharyngeal lymph nodes, and CT and MR showed that 14 cases of parapharyngeal space involvement. In addition, MR found 14 cases of anterior cervical muscle involvement. In displaying bone involvement,
