| 摘 要： | 目的:研究鼻咽癌多层螺旋CT各灌注参数的改变和良恶性肿瘤的鉴别诊断.方法:30例鼻咽癌患者行鼻咽血流的CT灌注扫描,30例鼻咽癌患者中有25例行放疗后复查,其中复查时行灌注扫描6例.应用去卷积算法模式计算相应病变区域的血流量(BF)、血容量(BV)、平均通过时间(MTT)和毛细血管通透性(PS).根据不同肿瘤的相关参数图来评价鼻咽癌血流动力学状态.结果:30例鼻咽癌患者BF、BV和PS明显高于肿瘤放疗后组织及正常鼻咽组织,而MTT值差异无统计学意义,结论:灌注参数BF、BV和PS可有效地评价鼻咽癌的血流状态,在鼻咽良恶性病变的鉴别诊断及预后的判断上有重要的临床参考价值.

| Abstract: | Objective:To study MSCT perfusion imaging of nasopharyngeal cancer and its differentiated diagnosis.Method: Thirty cases with nasopharyngeal cancer performed multi-detector CT perfusion examination.Among them,there were 6 cases of 25 post-radiotherapy patients performed perfusion imaging with CT scan.Nasopharynx perfusion parameters include blood flow(BF),blood volume(BV),mean transit time(MTT) and permeability surface(PS).Result:Compared with normal region of nasopharynx,BF,BV and PS in nasopharyngeal cancer increased significantly,while MTT has not significant difference between these two areas.Conclusion:Nasopharynx perfusion parameters(BF,BV and PS) measured with CT were significantly altered in nasopharyngeal cancer.There was important appliance value in differentiated diagnosis of nasopharyngeal malignant neoplasms and evaluation of outcome of radiotherapy of nasopharyngeal cancer. |
