摘要
目的 探讨磁共振MAGIC(magnetic resonance imaging compilation,MAGIC)成像技术在脑转移瘤中的应用价值.方法 分析30名脑转移瘤患者的影像学资料,比较增强MAGIC序列与常规增强序列图像信噪比SNR;记录两种序列图像检出脑转移瘤的数量及位置分布情况;以及分析两种图像整体质量评分、病灶细节评分和伪影评分.结果 增强MAGIC序列中T1WI、T2WI、T1WI-Flair和T2WI-Flair图像的信噪比SNR均高于常规增强序列,且差异具有统计学意义(t=32.685,t=29.158,t=22.939,t=21.608;P均＜0.001).增强MAGIC序列图像与常规增强序列图像在检出脑转移瘤的数量及位置情况方面无明显差别.增强MAGIC序列图像与常规增强序列图像在整体质量评分、病灶细节评分和伪影评分比较差异无统计学意义(t=0.213,t=0.109,t=0.659;P均＞0.05).结论 磁共振增强MAGIC序列扫描可以清楚地显示脑转移瘤病灶的位置和数量,并且具有较高的信噪比,为制定临床治疗方案和进行预后判断提供了可靠的依据.
Abstract
Objective To investigate the application value of magnetic resonance imaging compilation(MAGIC)in brain metastases.Methods The imaging data of 30 patients with brain metastases were analyzed,and the SNR of enhanced MAGIC images was compared with that of conventional enhanced images.The number and location distribution of brain metastases detected by two kinds of sequential images were recorded.The overall quality score,focal detail score and pseudo-film score of the two images were analyzed.Results The SNR of T1WI,T2WI,T1WI-FLAIR and T2WI-FLAIR images in enhanced MAGIC sequences was higher than that in conventional enhanced sequences,and the difference was statistically significant(t=32.685,t=29.158,t=22.939,t=21.608;P＜0.001).There was no significant difference in the number and location of brain metastases detected between the enhanced MAGIC images and the conventional enhanced images.There was no significant difference between the enhanced MAGIC images and the conventional enhanced images in overall quality score,focal detail score and pseudo-film score(t=0.213,t=0.109,t=0.659;All P＞0.05).Conclusion Magnetic resonance enhanced MAGIC scan can clearly display the location and number of brain metastases,and has a high signal-to-noise ratio,which provides a reliable basis for making clinical treatment plan and prognostic judgment.
