鼻咽癌放疗后磁共振灌注成像43例临床分析
Clinical research of PWI in nasopharyngeal carcinoma after radiotherapy
摘要
Abstract
Objective To investigate the clinical significance of the peffusion weighted magnetic resonance imaging (PWI) of follow-up after radiotherapy between recurrent nasopharyngeal carcinoma (NPC) and radio-fibrosis.Methods PWI examination was applied in 43 cases with NPC diagnosed by pathology after radiotherapy,including 9 cases of recurrence proven by pathology, and 3 of skull base erosion by MRI.The pcolor of maximal increasing slope (Slopemax) and signal intensity-time curve (SI-T) were observed.Results The pcolors of radio-fibrosis were shown in blue of ROI, and the recurrence was shown in red.The mean of Solpemax was compared between recurrent nasopharyngeal carcinoma and radio-fibrosis, and there was statistically significant difference ( P ＜ 0.05 ).Conclusion PWI is helpful for differential diagnosis of radio-fibrosis and local recurrence after radiotherapy, which is the preferred technique of follow-up after radiotherapy in NPC.关键词
