摘　　要：目的:应用磁共振动脉自旋标记成像(Arterial Spin-Labeled Perfusion MRI,ASL)定量测量鼻咽癌放疗后1年的鼻咽壁CBF值,讨探ASL技术在鼻咽癌放疗后复发的诊断价值。方法:选择100例鼻咽癌患者,均行常规鼻咽部MR和ASL序列扫描,并测量常规鼻咽部MR显示鼻咽壁增厚或病灶区域CBF值,按病理或随访结果分组,采用SPSS15.0统计学软件分析鼻咽癌复发CBF值。结果:鼻咽癌放疗后1年的复发灶与非复发灶的CBF值F<0.05。结论:ASL所得参数对于评价鼻咽癌放疗后是否复发具有重要意义。Objective:To explore Arterial Spin Labeled Perfusion MRI(ASL) was applied to quantitatively measure the nasopharyngeal wall CBF value 1 year after radiotherapy for nasopharyngeal carcinoma, so as to investigate the diagnostic value of ASL in the recurrence of nasopharyngeal carcinoma after radiotherapy. Methods:One hundred patients with nasopharyngeal carcinoma were selected, and conventional nasopharyngeal MR and ASL sequence scanning were performed, and conventional nasopharyngeal MR showed thickening of nasopharyngeal wall or CBF value in the lesion area. The CBF value of recurrent nasopharyngeal carcinoma was analyzed by SPSS15.0 statistical software according to pathological or follow-up results.Results: The CBF value of recurrent and non-recurrent lesions 1 year after radiotherapy for nasopharyngeal carcinoma was <0.05.Conclusion:The parameters obtained by ASL are of great significance in evaluating whether nasopharyngeal carcinoma has recurrence after radiotherapy.
