摘要/Abstract

摘要： 目的：比较流动敏感交互反转恢复（FAIR）与MR磁敏感对比剂动态增强（DSCMR）技术评价颅内肿瘤血流灌注的价值。方法：对33例颅内肿瘤患者行FAIR和DSCMR脑灌注成像，分别测定FAIR值和脑血容量（CBV）值，对其进行相关分析，并比较良、恶性胶质瘤之间FAIR值与CBV值之间的差异。结果：FAIR值与CBV值之间呈正线性相关（r=0.450，P=0.009）。良性胶质瘤CBV值平均为164.31±109.20，恶性胶质瘤的CBV值平均为365.12±177.41，两者之间差异有统计学意义（Z=-2.213，P=0.027）。良性胶质瘤的FAIR值平均为37.83±46.07，恶性胶质瘤的FAIR值平均为101.90±103.83，两者之间差异有统计学意义（Z=-2.021，P=0.043）。结论：FAIR技术无需对比剂，所提供的血流灌注信息与DSCMR相符，有较大的临床应用潜力。

Abstract: Objective: To compare the effects of flowsensitive alternating inversion recovery (FAIR) and dynamic susceptibility contrast MR (DSCMR) perfusion technique in evaluating intracranial tumor vascularization. Methods: Thirtythree patients suffering from intracranial tumors were determined by using the FAIR and DSCMR perfusion techniques. The values of FAIR and CBV were recorded and analyzed by the linear correlation analysis method. The values of FAIR and CBV between benign and malignant gliomas were statistically analyzed. Results： There was a positive linear correlation between FAIR and CBV(r=0.450，P=0.009). The difference of the CBV value between benign and malignant gliomas was statistical (Z=-2.213，P=0.027). So was that of the FAIR value (Z=-2.021，P=0.043). Conclusion： FAIR does not need a contrast agent and could offer some comparable perfusion information to DSCMR technique to clinicians, so it has the potential to be clinically applied.
