摘要:

目的 研究 3D 自由呼吸风车技术(MultiVane XD)结合化学位移技术水脂分离成像(Dixon)序列在颈部磁共振(MR)增强中的应用价值。方法 对 61 例患者采用 3D MultiVane XD Dixon 序列及常规T1WI 频率衰减反转恢复(SPAIR)增强序列进行颈部磁共振扫描。将两组增强 T1WI 序列图像质量进行评分并统计学分析。结果 在脂肪抑制与图像伪影方面,3D MultiVane XD Dixon 序列图像质量评分高于常规 T1W SPAIR 序列,两者差异具有统计学意义(P < 0.05);在软组织分辨率方面,常规 T1W SPAIR 序列图像质量评分高于 3D MultiVane XD Dixon 序列,两者差异具有统计学意义(P < 0.05)。结论 3D MultiVaneXD Dixon 序列能明显降低颈部 MR 增强吞咽呼吸、血管搏动及金属磁敏感伪影,脂肪抑制效果好,在显示颈胸交界区有绝对优势,对临床诊断颈部疾病具有重要的应用价值。

Abstract:

Objective The study aimed to investigate the application value of 3D free breathing pinwheeltechnology(Multi Vane XD)combined with chemical shift technology hydrolipid separation imaging (Dixon)sequence in cervical magnetic resonance(MR)enhancement. Methods A total of 61 patients underwent neckMRI scans using 3D MultiVane XD Dixon sequence and conventional T1WI frequency attenuated inversion recovery(SPAIR)enhanced sequence. The image quality of enhanced T1WI sequences in the two groups were scored andstatistically analyzed. Results In terms of fat suppression and image artifacts,the image quality score of 3DMultiVane XD Dixon sequence was higher than that of conventional T1W SPAIR sequence,and the difference wasstatistically significant(P < 0.05). It was higher than 3D MultiVane XD Dixon sequence and the difference wasstatistically significant(P < 0.05). Conclusion 3D MultiVane XD Dixon sequence could significantly reduceneck MR ⁃ enhanced swallowing and breathing,vascular pulsation and metal susceptibility artifacts,which has agood fat suppression effect.
