摘要目的对比分析T1WI_Star_VIBE_FS序列在头颈部肿瘤患者MR定位中不同扫描方式对图像质量、信噪比、对比噪声比等参数的影响,确定优选扫描方式。方法回顾性分析 78例头颈部MR定位患者,分别采用组织补偿法(A组 23例)、分段扫描拼接法(B组 18例)和二者结合法(C组 37例)进行增强扫描,对比上述3种扫描方式获取的图像质量、颈前部软组织信噪比(SNR)和对比噪声比(CNR)的差异。结果 C组扫描方式可获取较高的图像质量评分;3种扫描方式获取图像的SNR的平均值分别为 214.70±148.78、91.95±59.26、307.61±127.80;CNR的平均值分别为 208.74±148.27、85.79±59.50、301.58±127.48;C组在图像质量评分、SNR和CNR方面均明显优于A、B组(P<0.01)。结论推荐使用组织补偿和分段拼接扫描相结合方式作为头颈部肿瘤放疗MR定位的优选扫描方式。

Abstract：Objective To compare and analyze the image quality,signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of T1WI_Star_VIBE_FS sequence in MRI simulation of neck tumors with different scanning methods, aiming to determine the optimal scanning method. Methods A retrospective analysis of 78 patients receiving MRI contrast scan was performed. All patients were randomly divided into three groups according to three different scanning methods including bolus mode (group A,n=23), segmentation splicing mode (group B,n=18) and the combination mode (group C,n=37). The image quality, SNR and CNR of the anterior soft tissues of neck were statistically compared. Results A higher image quality score was obtained in group C. The mean SNR and CNR in three groups were calculated as 214.70±148.78,91.95±59.26,307.61±127.80, and 208.74±148.27,85.79±59.50,301.58±127.48, respectively. The image quality score,SNR and CNR in group C were significantly better compared with those in group A and B (all P<0.01). Conclusion Combination of bolus and segmentation splicing modes is a recommended approach in MRI simulation during radiotherapy of neck tumors.
